CITY COUNCIL AGENDA
ITEM NO. 9
TO: Mayor and Members of the City Council
FROM: Public Works Department
SUBJECT: DIGITAL ORTHOPHOTOGRAPHY SERVICES — APPROVAL OF
PROFESSIONAL SERVICES AGREEMENT WITH MERRICK & COMPANY
RECOMMENDATIONS:
Approve a Professional Services Agreement with Merrick & Company, of Aurora,
Colorado, for digital orthophotography services at a contract price of $125,117 and
authorize the Mayor and City Clerk to execute the Agreement.
2. Establish an amount of $12,511 to cover the cost of unforeseen work.
DISCUSSION:
Digital orthophotography is computerized aerial photography that has been corrected in a
manner that places all visible ground features in their true map position and also corrects
displacement due to relief or tilt. Any other graphical data owned or created by the City that is
in the same coordinate system will fit over the digital orthophotography precisely, in its true
earth - referenced position. The high resolution imagery desired by the City will allow staff to
zoom in and see very small features on the ground, and will make the imagery useful for a large
number of infrastructure planning, utility planning, operations, and management tasks within the
City.
The digital orthophotography creation process involves scanning the aerial photography at very
high resolutions, and through sophisticated image processing techniques, warping it to fit the
terrain data that was collected with analytical stereoplotters. The completed imagery is
delivered on CD -ROM disks in industry standard formats, ready for immediate use. Availability
of the digital aerials would save staff time and produce accurate, useable data for all City
Departments. Rather than going to the Public Works Dept. (which may be across town for
some) and get another person to pull out possibly numerous and cumbersome hard -copy
aerials (the subject area may fall across several large sheets), the aerials could be viewed on a
computer monitor with pertinent or all GIS layers.
There are several CD -ROM programs being sold for a much lower cost offering digital aerials with
1 -meter imagery. This means 1 -meter pixel resolution. Exhibit "A" in your package is an example
of what this resolution looks like when zooming into a smaller area at the map standard of 1 inch =
40 feet. The proposed project produces imagery with 3 -inch pixel resolution. Exhibit "B" is an
example of this resolution.
The Police Department has stated the ability to quickly access and view detailed geographical
information of the City electronically will enhance public safety by allowing personnel to be
deployed more effectively in tactical situations, neighborhood canvasses, or crime scenes.

Digital aerial photographs can also display other types of information including lot and street
layouts, hazards, elevation depictions, access points, and City boundaries. The Police
Department intends to make this technology available in every marked police vehicle deployed in
the field and available to the detectives and dispatchers in the station. In addition, Staff from Fire,
Harbor Resources, Planning, and General Services Departments has seen samples of the
digital aerials and support the project.
Eight engineering firms were invited to submit proposals to provide digital orthophotography
services and to produce aerial photography of the City of Newport Beach (including the
Newport Coast area) in a digital file format. The proposed services include providing digital
aerial photos and the "MrSid" software to compress and manage the digital files (this software
allows speedy display of images).
Six firms responded to the City's request for proposals:
• Landata Airborne Systems
• HJW (Harmmon, Jensen, Wallen & Associates, Inc.)
• Merrick & Company
• Digital Map Products
• Walker Associates
• SACOR3D
The proposals were independently reviewed to evaluate
experience on similar projects, and availability before ranking

provide the necessary scope of
completed engineering services
Ier local agencies in Southern
The scope of Merrick & Company's professional services will include:
• Ground Control Survey to mark location of "targets" throughout the area to
be photographed
• Aerial Photography (by Continental Aerial Photo, Inc. of Los Alamitos,
California) with Airborne GPS to supplement targeted field control and to meet
positional accuracy requirements
• Photo Lab Work for printing and processing of contact prints
• Analytical Aerotriangulation and Contour Generation to accurately join all
flight lines, apply corrections for lens distortion, earth curvature, atmospheric
refraction, and film shrinkage, and to examine all control points to ensure the
accuracy level of mapping selected by the City
• Film Scanning to produce digital imagery in preparation for orthorectification
• Orthorectification involves georeferencing the digital imagery to the digital
terrain models in order to remove all relief displacement from the raw images
at ground level on a pixel by pixel basis, thereby producing color photos with 3-
inch pixels
• Mosaicking to ensure that no image flaws result from seam lines passing
through tall structures and bridge locations
• Radiometric Adjustment to balance and match color tones, brightness, and
contrast of the imagery over the whole project

communication and decision - making efficient. Our team strongly
believes that communication is at the core of a successful project
relationship. This effective communication strategy has allowed Merrick
to work throughout the US from our central office in Denver.
3. Items that are recorded and stored by each team member are:
• Primary contacts (administrative, technical)
• Secondary contacts (administrative, technical)
• E -mail addresses
• Scheduled conference call times for project status
• Scheduled on -site visits at Merrick and Newport Beach
4. In addition to the communication items, Merrick prepares its production
facility for the project. The primary tasks being integrated in preparation
of beginning the project are:
• Scheduling of resources (equipment and personnel)
• Preparation of the technical procedures documentation
• Customizing in -house software tools
• Prototype the production flow with Newport Beach and Merrick
5. A project of this size requires a start-up time frame of approximately one
week. Once the information is gathered and /or tested, the team is ready
to begin the next step of the project.
Step 3 — Surveying Support for the Photo Control
1. In order to achieve the accuracy and schedule objectives of Newport
Beach, Merrick will utilize standard survey and photogrammetry
procedures to control the aerial photography. The procedure takes
advantage of the highly accurate Airborne GPS ( ABGPS) technology to
minimize the amount of control required to meet positional accuracy
requirements.
2. Additionally, a photo - identification (photo -ID) technique will be used,
requiring fewer points to be premarked prior to flying the aerial
photography. This methodology allows more flexibility in film
acquisition, opening a longer flight window and ability to wait for an
optimal day where environmental conditions are best suited for ortho
imagery. This is an important aspect of the photography mission given
the sometimes -foggy conditions that exist along the coast.
3. Merrick's GPS control will be referenced to not less than two of Orange
County's survey points that presently exists within and surrounding the
City. Based on this approach, there will be 12 photo- identification
(photo -ID) points.
4. Because the ABGPS technology provides X, Y, Z coordinates for every
exposure; the 12 photo -ID points are merely random quality inspection

points that will validate the accuracy of the ABGPS and Fully Analytical
Aerial Triangulation (FAAT).
5. The photo -ID control will be based on aerial mapping needs and the
precision will be adequate to support national Map Accuracy Standards
for I" =100' mapping with two -foot contours.
6. All control will be based on the California State Plane Coordinate
System, Zone 6, North American Datum 83 -92. This project will be tied
to the closest High Accuracy Reference Network (HARN) points.
7. Vertical control will be referenced to North American Vertical Datum 88.
8. A preliminary control plan has been included in this proposal.
Step 3a — photo - Identification GPS
1. Once the aerial photography has been successfully flown, Merrick's
photogrammetrist will be responsible to select the photo - identifiable
points that will be GPSed.
2. As the City will notice in the flight line control diagram in "K.
MISCELLANEOUS," the photo -ID points are evenly distributed throughout
the project. These points will verify the positional accuracy of the
FAAT.
Using a working set of contact prints, Merrick's photogrammetrist will
review each area needing a photo -ID point then select an exact location
that is clearly visible.
4. Next, each photo -ID point is "pin- pricked" and fully described on the
back of the contact print. The GPS crew performs this in the field. The
GPS crew will also photograph the control points on the ground as they
are set and surveyed. The FAAT technicians to further verify the precise
location of the point will use these snapshots.
5. Features that make the best photo -ID points are those that are most visible
on the photography and easily accessible by the GPS crews. These points
tend to be in low traffic areas and away from tall buildings, trees and
other obstructions. The ideal photo -ID points are typically paint stripes in
low traffic streets or parking lots.
Step 4 — Acquire New Aerial Photography
1. As stated in the City's RFP, the project wide negative scale for the color
aerial photography will be 1:7,200 (1 "--600').
Merrick will utilize Continental Aerial Photo, Inc. to perform the
photography mission. Continental is located conveniently in Los
Alamitos, California, very near to Newport Beach. This will minimize
the mobilization time for the flight crew and make it easier to be
responsive to unexpected clear skies. The Wild RC -30 camera drive unit
incorporates forward motion compensation (FMC). Additionally,
Continental's aircraft is equipped with GPS navigation and on -board
receiver to accomplish the camera positioning for the aerotriangulation.

2. The aerial photography will conform to National Map Accuracy
Standards. The following additional project specifications will also be
strictly adhered to. These include:
• Flying under optimal weather conditions Such as cloud coverage and
sun angle
• Federal Aviation Administration (FAA) and Civil Aeronautics Board
(CAB) safety regulations
• State -of- the -art film processing
3. A current USGS camera calibration report meeting specifications for
focal length (153 mm, t3.0) can be found in "K. MISCELLANEOUS." The
industry standard is that a camera calibration report not be older than
three years. Continental's camera was last calibrated in March of 1998, -
about 29 months ago. Though the City's RFP requires that the aerial
camera calibration not be more than two years old, Merrick is proposing
Continental's camera because of their convenient location near the
project area. Please note that the industry calibration standard is every
three years and that all, mapping accuracies and image qualities will not
be compromised using the proposed camera.
• Conformance to project related side overlap and forward overlap
specifications
• All flight lines will be straight and parallel
• Individual exposures must meet the tip, tilt and crab standards
4. The following photography characteristics apply:
Negative Scale: 1" = 600' (1:7,200)
Mapping Scale: I" = 100' (1:1,200)
Contour Interval: none required
(2' as alternative)
Flying Altitude: 3,600' above mean terrain
Forward Lap: 60%
Side Lap: 30%

Number of Exposures: 219
Number of Mapping Exposures: 167
Mapping Flight Lines: 13
Mapping Flight Line Miles: 63

5. The aerial photography shall be flown on, or near, the date designated by
the project manager following the contract signing, or as soon thereafter
as weather permits. Merrick anticipates that the aerial photography will
be flown in early October 2000, or as soon as Merrick receives a Notice
to Proceed.
6. Once the film is processed, inspected, and approved, each exposure shall
be clearly labeled at the edge of the negative. The labeling shall include:
date of photography, scale of photography, project name, flight line
number, and exposure number.

Of importance to the City
is Merrick's approach for
utilizing two GPS base
stations during the
photography mission.
C. PROPOSED SCOPE OF WORK
Page 5
7. A flight line plan is included in our proposal so that the City can see
exactly how Merrick intends to fly the aerial mission.
Step 5 - Airborne GPS Photo Control and Post Processing
Merrick and Continental Aerial Photo will use Airborne GPS (ABGPS) in
order to control the aerial photography. The following summarizes Merrick's
ABGPS procedures.
1. An Ashtech receiver will be used in the aircraft for the land based
reference points.
2. Of importance to the City is Merrick's approach for utilizing two GPS
base stations during the photography mission. Based on our experience,
having the extra receiver operating is important for two reasons: 1) it
provides the necessary back -up if one receiver "goes down "; and, 2) does
not "stretch" the practical limitation of GPS frequency over the City.
3. Moreover, having two base stations is the only way to assure proper geoid
modeling so that the aerial triangulation fits correctly and that the
photogrammetric map accuracies are achieved. Because of Merrick's
precise ABGPS procedure, the accuracy of the horizontal and vertical
positions of the photo centers will be ±3 cm (0.3') horizontal and ±5 cm
(0.5') vertical. These tolerances are suitable for the desired accuracy
requested by Newport Beach in this RFP.
4. The results from the kinematic data collection and/or data processing
shall be simple coordinate values for each common epoch of data
recorded by both the GPS receiver in the aircraft and a base receiver on
the ground.
5. The photos shall be represented only by an exact time corresponding to
the time that the GPS receiver recorded the electronic pulse from the
camera when the photo was taken. These times shall be labeled with
photo identifiers by referring to the trajectory plots and the pilot's flight
reports so that the line numbers match those used by the pilot and thus,
ensuring easy cross referencing. At the same time, test exposures and
events caused by blanks shall be removed from the event list.
6. The latest available geoid model shall be used to determine the separation
between the geoid and the ellipsoid.
7. Quality control will be performed by having loop closures through
multiple base stations.
8. Coordinates and elevations will be generated for the perspective center
for each photograph that will be used in the fully analytical aerial
triangulation process (FAAT).
Step 6 - Fully Analytical Aerotriangulation (FART)
I. Fully Analytical Aerotriangulation (FAAT) creates coordinates (X,Y) and
an elevation (Z) for supplemental photogrammetric points on each
photograph that are used in the stereo model orientation process (Model
Setup).

2. The FAAT process simultaneously corrects image displacement caused
by earth curvature, atmospheric refraction, camera lens distortion, and
aircraft (flight) inconsistencies.
Step 6a - Fully Analytical Aerotriangulation (FART) Preparation
I . The pre- marked photo control points, new pass and tie points will be
located, marked and numbered on the new aerial triangulation contact
prints. Each type of control point will have a unique symbol and point
number for easy identification in the remaining processes.
2. Pass and ties points are pre - selected stereoscopically by Merrick and the
location are marked on the contact print with a semi- permanent pen.
Each type of point has a unique symbol and point number for easy
identification in the remaining processes. Each stereo model has six pass
points and two tie points to the adjacent flight line. As each flight line is
completed, the targeted ground control, pass, and tie points are marked
and numbered on a strip diagram.
3. A stereo model diagram will be prepared for task tracking so the project
status can be continuously updated and monitored by the production
manager.
Step 6b - Control Point Transfer (Pugging)
1. A Wild Pug4 point transfer device equipped with a 60- micron drill bit
will be used to pug the analytical points.
2. The new pass and tie point locations will be placed in clear /flat areas with
good contrast. Hills, trees, and light surfaces will be avoided if possible.
3. The cross - pugging progress will be marked and monitored on the aerial
triangulation stereo model diagram.
Step 6c - Point Measurement on Zeiss P1 Analytical Stereoplofter
1. Once all pass and tie points are pugged, the analytic technician places the
photographs on stage plates in the Zeiss PI analytical stereoplotter.
Merrick owns five Zeiss PI analytical stereoplotters.
2. Photogrammetric technicians then read eight fiducials on each photograph.
This process checks film for shrinkage, expansion, distortion, and flatness
of the film.
3. Subsequently, operators clear all parallax from the stereo model and
locate/measure all pass points, tie points, and control locations.
4. Merrick assures that the mean error of all measured points does not exceed
three microns. (A Zeiss PI analytical stereoplotter is capable of measuring
a photograph ±I micron.)
5. After all photographs have been measured, Merrick creates a computer file
with photo coordinates for each photograph.

Step 6d - Process Aerotriangulation Data
I . After all the measurements are taken, the photo coordinates for each strip,
or flight line are loaded into the FAAT software (Albany.)
2. Each strip is computed separately with the proper degree of polynomials,
which is determined by the control configuration within the strip.
3. If any inconsistencies in the photogrammetric or field control data exist,
Merrick will correct and rerun until data is acceptable.
4. Tie Point Analysis (TPA) will be performed on all flight strips. TPA shows
relationship between flight lines (tie point to tie point) and spots any errors
that exist. All errors will be corrected at this stage.
5. Execute preliminary block adjustments that incorporate field control
throughout all points unlike the TPA that only deals with "photo
coordinates"
6. Execute space resection that computes all the orientation parameters.
7. Execute Pre - Albany. This program sorts all images and reorders orientation
parameters into the minimum bandwidth order.
8. Execute Albany to perform the final bundle adjustment for the entire
project area (block). This program gives final root mean square (RMS)
misclosures at all horizontal and vertical control points. In addition, final
coordinates are derived for all analytical points (pass points and tie points).
9. Once Merrick's certified photogrammetrist accepts the solution, a report is
then prepared.
10. A comprehensive FAAT report of the results of the FAAT exercise will be
submitted to the City project manager. This report will include, at a
minimum, the following:
• Root Mean Squared (RMS) error and residuals of the final block
adjustment
• Root Mean Squared (RMS) error and residuals of the quality control
block adjustment
• Diagram of stereo model layout with photo centers
• Diagram of stereo model layout with control, tie and pass points
11. This report will be inspected and signed by Merrick's project manager,
Certified Photogrammetrist, and FAAT Analyst.
Step 7 - Develop the Ortho Imagery and DEM Prototype Project
I . Merrick and the City will select the prototype area once the GPS,
photography, and FAAT have been completed. The City will have an
opportunity to review the prototype databases. Following the prototype
review and approval by the City, the remaining project area will be
automated.
2. To prove the photogrammetric conversion methodology, a prototype
deliverables will be created. That is, a model or test will be created and
analyzed to insure our procedures and assumptions are valid. Merrick
believes we understand the complexity of this project and therefore do

prototype.
3. The prototype will be a representative sub -set of the entire project. Once
the City has approved the prototype, it will be used as a standard to
control image quality, contrast, density and accuracy for all future
deliverables.
The primary objectives of the prototype are:
• Validate that the ortho image and DEM data products being generated
will meet Newport Beach expectations.
• The prototype model will be used by the City to demonstrate and
communicate the purpose of the project to management and
administrators.
• Test the physical GIS database structure. The primary aspects of the
design will focus on defining and documenting important database
structure items such as:
• Tile naming conventions
• Boundary coverage
• DEM format
• Digital ortho radiometry
• The digital ortho imagery specifications will be scrutinized during the
prototype step in order to be sure that the image data conforms to the
predefined specifications of Newport Beach.
• Tonal Quality is a subjective attribute of digital ortho imagery
that is strictly dependent on a personal preference. Additionally,
the hardware and software being used by the City will influence
the visual aesthetics of the imagery. Merrick will use the
prototype project to determine the best tonal qualities based on
all of the above factors. This will be especially important over
water and other consistent tonal areas.
• Develop the communication protocol and response time expectation for
rectifying source document anomalies. Establish and strengthen the
working relationships between Merrick and Newport Beach.
• Develop /modify in -house and project quality control process which
minimize the time that is spent on inspection of each deliverable
product.
4. At the completion of the prototype conversion, a final implementation
plan and schedule will be submitted. This plan will incorporate the
knowledge and experience obtained during the development of the
prototype effort. The City would then provide Merrick authorization to
proceed on the project -wide automation.
Step 8 - Perform Model Orientation
1. After the database design has been finalized and the prototype completed,
Merrick will be ready to begin the stereo compilation for all of the project
area. This next step performs internal relative and absolute positioning of

each photo. To accomplish this, a least- squared analysis of each model
will be executed to obtain orientation residuals.
2. Merrick inspects all residuals to ensure conformance to accuracy
standards. Once approved, the stereoplotter operator will use these
values to compile into the precise coordinate system established for this
project.
3. Generate the Model Orientation Report to document the setup results for
each stereo model. Merrick's photogrammetric supervisors will approve
the setup and orientation of each model.
Step 9 - Load Adjacent Model Data
This step merges digital data collected from adjacent photographs to
verify that information on the edge of each photograph matches on each
image, resulting in a "seamless DEM database."
Step 10 - Photogrammetrically Collect Digital Elevation Model (DEM)
I. A DEM will be collected to produce the digital ortho imagery. A DEM is
a coarse representation of the terrain that is used in the digital ortho
rectification processes. The imagery created using the following DEM
methods will meet National Map Accuracy Standards for a I" =100'
digital orthophoto.
2. The three - dimensional (3 -D) digital elevation model (DEM) is formed by
collecting only major breaklines and mass points throughout each stereo
model. Breaklines are spots taken along abrupt changes in the terrain
such as major road crown, drainages, and ridgelines. Mass points are
spot observations taken at somewhat even intervals.
3. It is very important to mention that Merrick does not cut corners on the
DEM collection process. That is, there are many ways to reduce the time
required to collect a DEM. Unfortunately, by cutting corners, the cost to
produce the DEM becomes very low. Merrick encourages the City to
carefully scrutinize the process being used to generate the DEM for this
project. This is an important aspect because it will impact the City's
ability to overlay other data sets on to the imagery.
4. Merrick's DEM will have approximately 2,000 - 4,000 points per tile.
Actual point density depends on the type of area being modeled (rural,
urban, etc.) and degree of relief change.
5. Merrick creates the DEM in the following standardized steps.
• Collect 3 -D discontinuity lines along all major terrain breaks such as
road crowns, drainages, etc.
• Scan and create elevation profiles in parallel rows on each model at two
rows per inch at map scale.
• Verify accuracy and completeness of terrain model using Merrick's
software to routines inspect that scan lines conform to the
predetermined National Map Accuracy Standards (row spacing,
completeness, extent, point density, etc.).

C. PROPOSED SCOPE OF WORK

Step 11 - Digital Orthophotography Image Processing
The following is an overview of the process by which Merrick creates digital
orthophoto images. There are five main steps involved in creating a digital
ortho. These include:
• Creation and acceptance of the ortho Digital Elevation Model (DEM)
• Creation and acceptance of the planimetric databases
• Negative rasterization (scanning)
• Fully differential orthometric rectification
• Radiometric correction and image processing
• Data quality inspection and delivery
The major components of each step are outlined below.
Step 11a — Negative Rasterization (Scanning)
I. When scanning the film or diapositives, red, green, and blue histograms
or look -up tables (LUTs) are customized to establish the optimum "bell
shaped curve." This will assure the digital ortho imagery will have a
well - balanced array of tonal values.
2. Merrick will use the original (first generation) negatives to create a higher
quality image.
3. When handling the film, Merrick's scanning analyst uses extreme care
and white gloves. This procedure reduces the possibility of scratching.
4. Merrick always recommends maintaining the input scan small than the
final output resolution. We have found this to yield a higher quality
product for the client without increasing the cost.
5. The following table illustrates the relationship between photo scale, input
scan size and output pixel resolution.
Prolect Scale Photo Scale Input Scan Input Pixel Final Pixel
1" =100' 1" =600' 7 microns 0.17' 0.25'
Step 1 l — Digital Ortho Rectification
Establishing or defining the ground surface and scanned negative relationship
via digital orientation are the next step of the process. The ground surface is
defined by the validated DTM that Merrick has collected photo grammetrically.
During this process, digital images are geo- referenced to that surface using
Zeiss Phodis Digital Orientations, which generates an interior (from the
camera calibration report) and exterior orientation (from the FAAT) of the
scanned image. These orientations relate the scanned image to the camera and
subsequently the camera to the ground.
Merrick uses a suite of Zeiss digital image rectification and processing
packages to rigorously calculate and generate precision ortho data from the
original scanned negatives. Merrick will use a Cubic Convolution resampling
method, with the ability to edge- enhance or smooth an image as needed to
arrive at the best geometric and radiometric output possible in the commercial
market today.

Page 71
Step t t c- Correcting Bridge and Overpass Lean
1. In order to reduce the aesthetic impact of the radial displacement of tall
buildings and overpasses in some portions of the project, Merrick will
rectify additional exposures over some portions of the area. To
accomplish this, each exposure will be analyzed to determine the very
best frame to minimize feature displacement over these areas.
2. Based on scanned aerial photographs, the digital imagery used as the
source for resampling to a differentially rectified ortho accurately reflects
what the scanner saw in the photography while scanning the exposure.
As a central perspective image, the camera looks straight down at the
ground only at the point directly beneath the camera at the moment of
exposure. Everything else is seen in a wide -angle view, with buildings
and other above ground features leaning over to an ever - increasing degree
the farther away they are from the center of the photograph.
Merrick also uses these techniques to correct the lean of bridges and
overpasses. In the illustrations below, the first image is the ortho before
correcting the lean of an overpass. The second image demonstrates Merrick's
ability to: 1) modify the DEM; 2) rectify a portion of an adjacent exposure;
and 3) mosaic the overpass taken from a different perspective into the final
image.
Bridges and overpasses before image
Step t td — Tone Balancing
Using Silicon Graphic workstations and Stellacore OrthoVista software
for image processing and modification systems, the radiometric
characteristics of each image are automatically compared and adjusted to
a standard project histogram. This results in each ortho possessing
similar tonal quality throughout the entire project area. Each ortho image
will consist of a balanced array of color values. The following is a
sample of Merrick's in -house procedure to ensure the best tonal match
using the OrthoVista software:

After automatic tone balancing
Step 11e— Final Digital Ortho Quality Inspection
I. Prior to delivering the orthophoto products, rigorous inspection of each
image is performed by displaying each image and the surrounding images
on screen. Mismatches, DEM "breaks," and similar occurrences are
grounds for rejecting an image. This approach will generate a superior
overall image data set across the entire project area.
2. Each of the above steps in the imaging process is self- checking.
Therefore, each step of the production process has internal validation
measures that must be approved prior to proceeding to the next step.
Step 11f — Final Digital Ortho Formatting
Following the acceptance of the imagery, the final ortho images are then
formatted according to the final 3000' x 2000' tile grid.
Based on the grid layout proposed by the City, Merrick assumes that full tiles
will be delivered for those on the border of the City. Imagery falling outside
actual project area will be rectified with an Ortho DEM. This modeling
technique will only control the imagery for ortho- rectification procedures.
For this project, all imagery will be output as true color, TIFF format files
with a World File. This format is 100% readable by Arclnfo and AutoCAD.
Step 12 - Submit Ortho and DEM Databases to Newport Beach
I. Ship all maps and data.products to Newport Beach for verification and
inspection.
2. Merrick will work with Newport Beach to define quality control
procedures that optimize the City's staff and equipment resources.
Step 13 - Verify Deliverables by Newport Beach
1. Perform quality control on sample maps and data products.
2. Provide Merrick with review comments.

Two -Foot Contour Optional Procedure
C. PROPOSED SCOPE OF WORK
Page 14
The following narrative assumes that Merrick has successfully accomplished
the aerial photography, ABGPS, FAAT, and project design. If the DTM and
contour were selected by Newport Beach, it would replace the information
provided about creating a DEM. The DTM would be used for both rectifying
the digital ortho imagery and interpolating the two -foot contours.
Step 1 - Photogrammetrically Collect Digital Terrain Model (DTM)
1. If this alternative is selected, a DTM will be created using a
photogrammetric stereoplotter. The DTM is used to produce the digital
contour database at two -foot intervals.
2. The contours interpolated using the following DTM methods will meet
National Map Accuracy Standards (NMAS). Merrick's DTM data
collection is the most advanced and accurate procedure to model the
surface of the terrain.
3. Collecting breaklines and mass points throughout each stereo model
creates the three - dimensional (3 -D) digital terrain model (DTM).
Breaklines are spots taken along abrupt changes in the terrain such as
road edges, drainages and ridgelines. Mass points are spot observations
taken at somewhat even intervals.
Merrick recommends that the spacing be related to final map scale and
contour interval. When the distance between scan rows (grid density) is a
function of the final map scale, it maintains the position integrity of the
derived contour database. The following table illustrates the contour
interval and DTM by map scale.
Map Scale Contour Interval Mass Point Spacing Breaklines
1 " =100' 2' -100' All
Merrick's DTM will have approximately 8,000 - 14,000 points per tile
using the average approximate grid width. Actual point density depends
on the type of area being modeled (rural, urban, etc.), level of planimetric
feature capture, and degree of relief change. DTMs are created using the
above grid spacing to guarantee that the topographic data conforms to
National Map Accuracy Standards. Merrick's DTM and contouring
procedures have been verified by field survey and are frequently used to
generate plan & profile'sheets, road/sewer design, drainage studies and
volumetric computations.
3. Merrick creates the DTM in four standardized steps:
• Collect 3 -D discontinuity lines along all terrain breaks, such as road
edge, curb step -ups (2' contour only); knobs; major road crown;
drainages, ridges, etc.
• Scan and create elevation profiles (grids) on each model.
• Stereo digitize spot' elevations of all high -low points, such as toe and
crests, saddles, buttes and street intersections.

order to accurately model
the terrain.

DTM in a post - process.
C. PROPOSED SCOPE OF WORK
Page 15
Create obscurity lines (closed areas) where terrain data may be
obscured by dense vegetation or shadow.
4. Breaklines are the most important part of a digital terrain model.
Merrick's DTM collection "rules" are very rigid in order to accurately
model the terrain. The following summarizes some specific criteria used
by Merrick to compile breaklines:
• Terrain "breaks" greater than Y. the contour interval typically require
breaklines.
• Planimetric features (hydrography and road edge) that are also
breaklines are typically duplicated as both a feature and a breakline.
• Minimums of three breaklines are needed to define a ditch or drain
and four breaklines are required to define a graded berm or railroad
grade.
• Breaklines are collected as paired sets. They delineate planar
surfaces which, when combined together, give the basic shape of the
ground being modeled. In modern contour interpolation programs,
the basic character of the ground is determined from breakline
collection.
• When collecting breaklines care is taken so that they do not conflict
with each other and the mass point data.
• In very steep terrain, cliff areas need at least a breakline at the top and
bottom of the feature. Skipping scan point collection on near vertical
cliff faces will generate better - looking contours.
• Checks are done to make sure that the cliff is not an "overhang." If
the lower breakline crosses under the upper breakline, the contours
generated will be incorrect.
• Checks are made into adjacent tie stereo models to guarantee that
breaklines are continuous.
5. Verify accuracy and completeness of terrain model using Merrick's
proprietary software to inspect that scan lines conform to the
predetermined accuracy standards (row spacing, completeness, extent,
point density, etc.).
Step 1a - Compiling Spot Elevations
Merrick's spot elevations are compiled on the stereoplotter and not
interpolated from the DTM in a post - process. The spot elevations are
also used as an independent verification of the positional accuracy of the
contour data.
2. As the City is aware, National Map Accuracy standard of ±' /a of the
contour interval is the standard for this feature.
3. Spot elevations are collected based on the unique characteristics of the
terrain. At a minimum, spot elevations are collected for the cultural
features at every street intersection, railroad crossing, bend in a road, in
roads over a culvert, cul -de -sac centers, bridges, and culvert ends.

Mass Points and Breaklines
Triangulated Irregular Network
Topographic & Planimetric Data
C. PROPOSED SCOPE OF WORK
Page 16
For the physical features, spot elevations are collected at water elevation,
on high (peaks, buttes); and, low (saddles, depressions) areas. Spots are
also collected, between contour lines when they are more that 1" apart
(100' at final map scale).
Step 2 - Create Topographic Databases
I. Following the photogrammetric compilation of the DTM, Merrick utilizes
SiteWorks to process the DTM and interpolate the final 5' contours (I' or
2' interval if selected by any of the participating Cities). SiteWorks is an
engineering software package that work within Intergraph's MicroStation.
2. The points in the DTM are related and connected to each other by
creating a Triangulated Irregular Network, also known as a TIN.
Drawing 3 -D triangles whose corners are the DTM points creates the
TIN.
When the points in the. DTM are collected "on the ground" and in a
sufficient density, the legs of the triangles that connect the points should
accurately represent the surface of the terrain. These triangles that are
created to make the TIN are "drawn" within the contour interpolation
(CEP) software according to certain rules.
The principle rule is that breaklines act as a "hinge" for any triangulation
that would pass through them. That is, any triangulation that tries to get
past a breakline by going over or under it is forced to go up or down to
that breakline and then. continue on from there. This prevents the TIN
from "submarining" through ridges or "bridging" over drains.
3. The next step is to process the DTM and create the contour levels using
Merrick's contour interpolation software (CEP). After processing,
attributes for elevation and line type are automatically populated for each
line.
The DTM will be interpolated to create a topographic map having the
pre- defined contour interval. Contour data will be interpolated across
sheet (tile) edges to form a continuous line. Use predetermined tile and
sub -tile layout to "clip" continuous data into individual tiles.
4. Creating an aesthetic cartographic contour map is the next step in the
process. At the editing workstation, contours are smoothed, enhanced,
and verified. During the prototype, Merrick will work with the City to
determine the cartographic quality of the contour database.
5. Next, a final inspection of the vertical accuracy is performed by
comparing spot elevations to interpolated contours. This essential,
independent, validation proves the accuracy of the contours.
6. Merrick utilizes in -house GIS software tools to programmatically create
topologically correct coverages, validate edgematching, annotate index
contour lines, and attribute contours. Merrick understands the
cartographic, topologic, and engineering database implications when
creating and editing digital data. That is, data products are more complex
than conventional maps, therefore, advanced computer expertise, such as

that found at Merrick, are essential to Newport Beach for a successful
project.
7. Merrick's processing software develops 3 -D vector contour files, patterns
lines and automatically inserts attributes based on the database design
standards.
Step 3 - Creating Arcinfo Topography Databases
1. Merrick will convert the newly compiled topographic databases (.DGN)
into ARC coverages using ARCIGDS software tools. Similarly, software
called CATS4 is used to convert the DGN files into AutoCAD files.
Merrick and ESRI have used these data translation tools successfully over
the past five years. The software uses a series of translation tables to
"map" features into the appropriate coverages.
2. Merrick's existing AMLs and ARC tools will be customized to meet the
specific QC /QA requirements of Newport Beach. If desired by the City,
Merrick can make selected AML tools available to expedite their QC.
3. Following the on -line completeness verification, Merrick will then make
corrections, if needed.
4. A quality inspection plot is created of the topographic databases. These
plots are then edited by the photogrammetric supervisor and the project
manager for conformance to the project standards. Additionally, the
following items will be inspected:
• Edgematching of contour line that span tiles.
• Cartographic consistency, line smoothness and zero length line
segments.
• Conformance to pre- determined node and vertice standards.
• Polygonal features must close perfectly (obscured areas).
• Verify that label and line attributes are consistent (elevation and line
type).
5. Merrick's detailed QA/QC manual is available to Newport Beach to
review at the project "kick -off' meeting.
Step 4 - Final Quality Inspection of the Topographic Data
1. Thorough quality inspection procedures will be incorporated during each
phase of the conversion project thereby minimizing the amount of quality
inspection required at this stage.
2. Verify that ArcInfo contour database conforms to the specifications:
• Coverage tolerances and name.
• Definition of user defined attributes.
• Annotation specifications.
3. Review the databases and plots to see that they conform to the project
specifications prior to shipping to the City.

Quality Control /Quality Assurance
C. PROPOSED SCOPE OF WORK
Page 18
The following summarizes Merrick QA/QC procedures to be used on
Newport Beach digital mapping project. Merrick utilizes quality
control /quality assurances (QA/QC) throughout all phases of a
photogrammetric mapping project. The following section summarizes the
quality checks to be performed.
Compliance With ANSVASQC 0- 900211994 (ISO -9002)
Merrick's Corporate Quality System Manual amplifies our quality objectives
and defines the essential elements of the Merrick Quality System including
specific responsibilities for implementation.
In order to ensure uniform understanding of these elements, each core team is
required to document its Quality System in a Project Quality Plan (PQP).
Implementing procedures and instructions for the control of processes within
its operations shall also be documented.
These implementing procedures may include Quality Assurance Procedures
(QAP), Project Administrative Procedures (PAP), Project Design Procedures
(PDP), and Project Construction Procedures (PCP), which are under the
control of the Core Team Leader.
The Quality System, as implemented, is based upon the guidelines as defined
in the International Standard ISO 9001, Model of Quality Assurance in
design/development, production, installation, and servicing. The structure of
the Merrick Quality System consists of:
• ISO 9002 Guidelines
• Quality System Manual - Corporate
• PQP, Procedures, and Standards
IS09002 Corporate Endorsement
The management of Merrick endorses the policies in this manual and certifies
that this manual correctly describes the quality system in use within Merrick.
The signatures affirm that management of organizations participating in the
quality system will review the status and adequacy of the part of the system
they are executing.
Merrick QA/QC Procedures
Merrick utilizes strict quality control /quality assurances (QA/QC) throughout
all phases of a photogrammetric mapping project. The client can review these
procedures at any time throughout the mapping process. The following

Many manual verification
procedures will be

guarantee that the data
and cartographic
products conform to
project standards.
Manual Quality Checks To Be Performed
C. PROPOSED SCOPE OF WORK
Page 19
Many manual verification procedures will be implemented to guarantee that
the data and cartographic products conform to project standards. The
following checks will be manually performed:
• Inspection of production reports
• Inspection of QC maps
• Inspection of QC reports
• Visual check of content (existence of required features)
• Cartographic placement of all text and symbols
• Cartographic inspection that all topographic and planimetric features
match along the edge of adjacent map sheets
• Graphic comparison of data to the source document (aerial
photograph)
• Complete deliverables report, transmittal, and data certification
Automated Quality Checks To Be Performed
Wherever feasible, automated procedures (many developed using in -house
programming) expedite the verification and acceptance of the cartographic
map products and databases. As described above, Merrick uses a wide
variety of automated tools (C, MicroStation - LISP, AML, Intergraph User
Commands, etc.) to create efficient editing and validation programs.
The following QC items are commonly implemented during a conversion
project:
• Automated inventory /validation of all levels
• Automated plot generation
• Validation of the SPCS zone and double precision
• Interactive inspection of data, maps, and production reports
• Validation of tape format
• Conformance to file naming convention
• Validation of line attributes
• Validation of network topology of linear features
• Validation of correct annotation characteristics
To ensure the integrity and completeness of data and cartographic products,
Merrick will perform a quality inspection that includes a combination of
plotting of data and manual examination and automated verification checks.
GPS QA/QC
A minimum of three receivers, observing simultaneously, will be used in a
"leap frog" approach to the GPS observations. All antenna heights will be
measured in both meters and feet to guarantee and verify an accurate receiver
setup. Reviewing processed raw data and running loop closure checks will
check survey data collected from the field by receivers daily.

Loop closure tests of GPS observations will be performed to validate the
integrity of the data. Closures on the GPS network show the resulting
precision ratio in parts per million (PPM). Results are shown for each day of
observations and for the entire project. Coordinates are referenced to latitude
and longitude, while height is an ellipsoid value. The total distance traveled
along the traverse is displayed together with the accuracy in parts per million
(PPM). Also, the misclosures by the difference in X, Y, and Z Cartesian
coordinates (dx, dy, dz) are shown. Loop closures are done before any
adjustment and before any constrainment of the GPS network. The latitude
and longitude coordinates and ellipsoid heights from loop closures are not to
be used as final coordinates.
An error ellipse is used to show each point's expected horizontal coordinate
standard error. The scale of the plots is shown by the bar ticks running
through the ellipses and by the tag at the bottom of the page of the display
indicating the bar scale tick value. The scale is the same for all pages of the
displayed ellipses. The point name is shown at the lower left of each ellipse
and the angle (measured counterclockwise from the positive east bar scale)
made by the major ellipse axis is shown at the lower right. The sigma scalar
shows the ellipses in the 95% confidence region.
Analytical Aerotriangulation QA/QC
All targeted and photo - identifiable field control points are located and
annotated on a set of contact prints, and checked by the surveyor, or client, to
ensure that no points are misidentified and all points have been located.
The analytical technician will pug each pass point in digital stereo to
guarantee all points are easily discernible and in open areas of average
contrast and relatively flat terrain.
The analytical technician will review the pugged scanned imagery to verify
not less than one tie point per stereo model is common to the adjacent flight
line, and that each stereo model contains not less than six pass points.
During pugged diapositive measurement on Zeiss PI analytical stereoplotters,
independent model solutions are computed, and refined photo coordinates are
checked to ensure that no point exceeds 10 microns of error. Hardcopies of
the refined photo coordinates are produced and checked by the analytical
technician for sequencing and transposition errors.
During the mensuration process, the analytical technician will check for
presence of gross errors, and take preventive measures during the
intermediate adjustment procedures. Ground control checkpoints are
frequently used to verify the ground control survey and aerotriangulation.
After the accuracy has beer' verified, the checkpoints will then be included in
the final aerotriangulation and in all subsequent stereo model setups.
Stereo Digitizing (Digital Data Compilation on the DEM) QA/QC
Prior to initiation of stereo'compilation, both the project manager and
Assistant project manager review the project specifications and procedures in
detail with the photogrammetric team.

C. PROPOSED SCOPE OF WORK
Page 21
The project manager and/or the client generate a stereo model setup report for
each stereo model for review. However, each photogrammetric technician is
responsible for ensuring the model setup meets or exceeds project
specifications.
Upon completion of the stereo model, the digital data is processed at the
compilation station to verify the elevation model completeness. This
software verifies scan row spacing, point duplication, point density, and ridge
and drain separations.
Additionally, a final model setup report is generated and verified to ensure
that model orientation remained constant during compilation. This step
compares the coordinates defined during the FAAT with those read by the
photogrammetrist.
Another QC step is to review the area that the DEM data was collected. That
is, it is important to be sure that the entire project area is being covered, in
addition to a 2" buffer at the final mapping scale.
As a final check, the photogrammetrist views the DEM in an isometric view
to look for "spikes" in the elevation data that would create incorrect digital
ortho imagery.
Digital Orthophoto Image CA/CC
A rigorous quality assurance program is implemented in all aspects of the
digital orthophoto production. This includes a quality check automatically
incorporated in each processing step. These checks ensure that the resulting
product meets or exceeds all accuracy and quality specifications.
Merrick utilizes the variable resolution of its Zeiss SCAI film scanner to
ensure that no loss of geometric accuracy occurs because of image scanning.
In addition to radiometric histogram evaluation and modification, the image
quality is carefully monitored. Because the visual quality of an image is a
subjective item, clients are encouraged to be involved in decisions that affect
the image's visual qualities.
Ultimately, orthophotos are as accurate as the rectification surface (DTM) on
which they are based. When Merrick photogrammetrically produces the
DTM, rigorous quality assurance procedures provide confidence that the
DTM and consequently the orthophoto meet or exceed specifications.
Several tests and checks are employed to verify that the ortho image is
correctly registered to the DTM to ±2 image pixels, well in excess of National
Mapping Accuracy Standards for the I"=100' scale of mapping.
In addition to the 3 -D checks on photo control points, Merrick observes image
boundaries and ortho sheet boundaries to determine that the images match.
When translated to ground units, agreement across boundaries must be within
the DTM accuracy specifications to be acceptable. When multiple photo
exposures are mosaic to form single sheet orthophotos, the image seams must
also agree within the DTM accuracy specifications.
Overall, image quality is reviewed to ensure that the imagery is of consistent
tone and contrast across the project area, and to specifically look for any
breaks or processing failures within the image. Any such breaks will be cause

for rejection and recreation of the affected sheets after determining the nature
of the problem.
Final image quality and geometric fit is reviewed prior to translation from our
native Intergraph environment to the client - specific file format. Once
translation has occurred, the translated images are displayed to ensure no
errors have occurred in translation. The images are the written to the
specified media for delivery to the client, and are backed up with all related
project data to assure data recovery for future operations.
Image Scanning
The Zeiss SCAI film scanner currently in place at Merrick will be used to
capture a fully populated color image for subsequent orthorectification.
Radiometric and Geometric quality is enhanced by the fact that the original
negative is used for input, with no image degradation occurring through
subsequent darkroom processes.
Image Rectification
Using the previously discussed Intergraph suite of orthorectification and
image processing software, all input data including the interior and exterior
orientations, Digital Elevation Model, scanned input image, coordinate files
and camera calibration data will provide the basis for pixel -by -pixel
orthorectification to the specified output resolution and format. We have the
option of using three different resampling techniques, including Nearest
Neighbor, Bilinear, and Cubic Convolution with Parameters.
Image Radiometry
All imagery will be populated with 8 -bit values covering a range from 0 to
255 for each color band (red, green, blue.) During masspoint/breakline
collection, we prefer to collect data out to the edges of map sheets to ensure
that there are no gaps in coverage, allowing generation of complete map
sheets with no zero -value pixels due to incomplete DTM coverage.
Image Mosaics
Use of the Zeiss OrthoVista processing software allows the mosaicking of
several different images to create the desired output map sheet coverage.
Tone and contrast are adjusted automatically between input images during
this process, with the images then feathered across a zone to eliminate seam
lines within the project area. Further processing, if required, is carried out
with both Intergraph Imager and AutoDodge packages to maximize image
quality across the entire project area.
As we scan the original flight negatives for maximum image quality on input,
it is not necessary to create a special set of ortho diapositives for scanning
purposes. We can, of course, use ortho diapositives as the scanning source if
so desired, but our experience has shown exceptional results in both
radiometry and geometry by scanning the film negatives as an original data
source.

Experience with many different projects has shown a consistent digital

on the input data, and is stated only for features at ground surface. Due to the
physics of the central perspective aerial photograph, buildings will exhibit
leans or displacements progressively from the center of the photograph, as
will bridges, overpasses and other features above ground level that have not
been modeled with the DTM data.
Registration and Scale Check
Each image is displayed onscreen both individually and in conjunction with
the surrounding map sheet images to ensure completeness of coverage, edge
matching, and tone matching. As part of that check, all panels or photo -id
control points are compared to the measured coordinates during survey to
ensure meeting stated accuracy standards.
Planimetrics are overlaid with the image data as well to check specifically for
correct fit, placement, and completeness of the data prior to final formatting
and delivery. Any discrepancies are noted and appropriate steps taken to
correct any errors in placement or fit.
Image Quality Check
As discussed previously, all scanned image data is rigorously reviewed during
the entire orthorectification process to guarantee maximum image quality on
output. This includes a final image review of all final format project images
to specifically check for edge matching and tonal consistency across the
entire project area, and to guarantee that no errors have been introduced at
any point along the production workflow.
Final Check
Planimetric and control point overlays are conducted as a matter of course
following output of the rectified image to specifically check for fit,
completeness and positioning errors. These checks are completed on the
initial output ortho, the formatted map sheet image after mosaicking, if any,
and on the final output format delivery files prior to delivery to eliminate any
chances for errors.
Personal Project Management Approach
It is Merrick's responsibility to satisfy the photogrammetry, mapping, and
ortho requirements of Newport Beach. Merrick will accomplish this
objective in many ways. In addition to implementing a proven technical
approach, Merrick's team will prepare all project deliverables so they
conform to National Mapping Accuracy Standards.
Merrick also uses a personal project management approach to communicate
project scope, issues, and status. The following summarizes the

Efficient and accurate communications between the Newport Beach project
team and Merrick will greatly contribute to the success of this project.
Merrick is not limited by our proximity. Therefore, project meetings at either
site can be arranged within a short notice.
Communication with the Newport Beach project team will be through the
Merrick technical/contract manager and/or project manager. Merrick's
technical /contract manager is Brian Raber, CMS and the project manager is
Richard Hanson, CP. Doyle Abrahamson, Merrick's in -house California
PLS, will support the project team from a technical management position.
Merrick and the Newport Beach project team are required to designate one
contact person for each of the following classes of issues: Mapping,
Technical, Schedule, Contract. The same person may be assigned to more
than one class. The designated person will initiate all communications
regarding a class of issues and all responses will be directed to that person. A
back -up person should also be designated for each class.
Merrick's Communication Protocol will be the procedure to document the
results of discussion and the decision made because of the communication
between Project Team members. In summary, all communication (fax,
telephone, transmittal, personal visit, etc.) is documented and stored in
Merrick's "Project Log." Additionally, telephone conversations that are
deemed to have significant value will be summarized and submitted to the
each key team member to guarantee an understanding of the conversation.
Status Reporting
The Project Status Report is used to communicate the status of each
conversion task. These Project Status Reports will be submitted based on a
bi- weekly schedule and will reflect project status as of the end of work on the
preceding day. Initially, the report will be faxed to the Newport Beach
project team. Status will be reported as the estimated percentage of
completion for each task identified in the report.
Meetings (at Newport Beach)
"Kick -Off" Meeting(s)
Merrick believes client interaction early in the process is very important and
necessary for a successful project implementation.
A meeting at the Newport Beach project team's offices shall take place
immediately after the contract is awarded. Merrick and the Newport Beach
project team will review all aspects of the scope of work in order to finalize
the contract for services. The purpose of this meeting is to guarantee that all
members of the Newport Beach project team and Merrick are in agreement
regarding all project - specific tasks.

Cost Estimating and Controlling Project Costs
Merrick uses a technical "Bottom -Up" approach to pricing all of our projects.
That is, our pricing represents the culmination of many technical assumptions
conceived by the technical team that will be responsible for satisfying the
requirements once Merrick is awarded the project.
The following summarizes the major technical assumptions that have a direct
influence on price.
Predefined project parameters:
• Square miles
• Number of exposures
• Number of model setups
• Quality of existing data to up -dated
• Complexity of the database design
• Specific planimetric features being collected
• Criteria of planimetric features
• Feature density
Undefined project parameters:

By knowing the above project characteristics, Merrick's experienced project
managers maintain the project budget and schedule that is committed to in the
contract.
Project Client Satisfaction Surveys
We "partner" with the City's technical and management staff to be sure that
the project is be implemented to the predetermined specifications. Moreover,
it is Merrick's project manager's ultimately responsibility to make sure that
Newport Beach is completely satisfied with the database being generated for
this project.
To assist Merrick's management and technical staff, a Client Satisfaction
Survey is accomplished at least three times during the "project life cycle."
The first Survey is given following the delivery of the Prototype databases.
The second is usually given following the acceptance of the first/second
major delivery milestone. The final Survey is given following the acceptance
of all the products at the Project Close -out meeting. An independent. person
at Merrick gives these surveys so that the City can provide "candid" feedback
to the project team.
Technical Alternatives
Alternative 1 — Citywide Compressed Imagery
Merrick recommends that the City consider producing a set of compressed
digital ortho imagery in a MrSID format delivered on a CD -ROM set or DLT
magnetic tape. Merrick will provide the MrSID log file so that the City could
see what the exact compression ratio is.
If this alternative is, selected, Merrick will compress the image dataset
utilizing MrSID compression technology by LizardTech, Inc. Merrick is a
business partner with LizardTech and has the ability to compress datasets in-
house and combine the dataset with Merrick's CAT -I extension. CAT -I is a
way for non - technical users to view digital ortho and vector data. A
description of Merrick CAT -I ArcView extension is included below.
As a value -added product, Merrick is providing Newport Beach, at no cost, a
solution for non - technical users to view and analyze the digital ortho
databases being created. This ArcView application developed by Merrick is
being provided at no additional expense to the City's primary participants.
CAT -I is explained in further detail below.
Alternative 2 - CAT -1 ArcView Extension for Viewing Digital ortho
Imagery
Merrick's Cataloged Image Management CAT -I is used to manage a Digital
Orthophotography Image Pyramid to display resampled images at differing
ground pixel resolutions to provide for rapid image display over a wide range
of scale. The application provides the user the ability to automatically load
only those images required for the current view's extent with the appropriate
pixel resolution for the display scale.

C. PROPOSED SCOPE OF WORK
Page 27
Merrick is an ESRI Authorized Application Development Business Partner.
CAT -I is built as an ArcView Extension to manage a Digital
Orthophotography Image Pyramid of resampled images or MrSID compressed
imagery. For this project, Merrick is providing the compressed imagery and
not the pyramid. As an ArcView Extension, CAT -I is not a proprietary,
standalone orthophoto viewing system. It provides you with all of the
functionality that you get with ArcView's standard graphical user interface
(GUI) plus additional functionality provided through open architecture
Avenue scripting.
CAT -I provides a custom GUI with the capability to add, create, and manage
multiple image catalogs with differing ground pixel resolutions or MrSID
database. This results in an Image Pyramid or compressed image database
that can than be accessed rapidly and efficiently. CAT -I allows the user to
pan and zoom in a view while automatically loading and displaying only
those images needed to support the current scale and extent of the view, This
reduces display time and provides for the capability to display larger areas
with less memory requirements. This is possible by minimizing the number
of images that are required to be loaded into memory and selects the smallest
image file size appropriate for the viewing scale.
CAT -I keeps the user informed of the ground pixel resolution that is currently
being displayed by updating the view's table of contents. CAT -I is also
capable of adding vector coverages (i.e., planimetric information) to overlay
the orthophotography. This can be accomplished by adding individual themes
to the Ortho View or by importing existing projects into a CAT -I enabled
project.
