AB# &I lb!? TITLE- APPROVAL OF AN AGREEMENT FOR
PROFESSIONAL SURVEYING AND MAPPING SERVICES
MTG. 4/24/O 1 TO PROVIDE DIGITAL AERIAL MAPPING AND CITY ATTY. CONTOUR DATA OF THE CITY AND APPROPRIATING FUNDS
DEPT. ENG
RECOMMENDED ACTION:
Adopt City Council Resolution No. gm /- /.% approving a consultant agreement for professional
surveying and mapping services with Merrick & Company, a Colorado Corporation to provide digital
aerial mapping and two-foot contour data of the City and appropriating funds.
Adopt Carlsbad Municipal Water District Resolution No. approving a consultant I \ a &
agreement for professional surveying and mapping services with Merrick 81 Company, a Colorado
Corporation to provide digital aerial mapping and two-foot contour data of the City and appropriating funds.
ITEM EXPLANATION:
The City of Carlsbad has a tremendous need for accurate and reliable aerial maps which show
current topographic and geographic features of the City landscape. The existing aerial maps used
by the City are outdated, lack the desired resolution and are not gee-referenced to the City’s
Geographic Information System database (that is to say the maps are not tied into the City’s survey
control monuments and cannot be relied upon as accurate). The only available citywide contour
data is 13 years old and does not accurately depict the changed landscape brought about by the
extensive development activity of the past 13 years.
City staff is currently working on several goals related to improving the functionality and capabilities
of the City’s Geographic Information System. It was staffs intention to develop a future goal around
the preparation of new, highly accurate and digitally rendered aerial maps covering the whole City.
The proposed maps would contain high resolution, full color imagery of the City and be tied to the
City’s established and proposed system of citywide survey control monumentation.
The City is now presented with the opportunity to obtain these needed and desired high quality
aerial maps at a substantial savings over the costs previously anticipated by staff. The San Diego
County Water Authority (SDCWA) has contracted with the mapping firm of Merrick and Company to produce high resolution, full color, digital aerial maps including two-foot contour data of all its
facilities throughout the County. As a separate part of their proposal, SDCWA asked Merrick to
provide estimates to do the same work for SDCWA-member cities under separate contract with the
individual cities. Significant cost savings can be realized due to economies of scale and due to the
effects of overlapping mapping needs at agency boundaries. Oceanside and Encinitas are moving forward with separate contracts to purchase the data for their jurisdictions.
The proposed mapping contract will produce two products:
1. Digital aerial photography geo-referenced for use with the City’s GIS database. The natural
colored imagery will be composed of individual pixels depicting ground objects measuring 6 inches across. The aerial mapping will extend approximately 3000 feet outside the City
borders. All maps will be tied to the City’s existing and proposed survey control network.
2. Digital topographic data depicting two-foot contour levels throughout the City and extending
approximately 3000 feet outside the City boundaries.
Page 2 of Agenda Bill No. ,I?,
The aerial photography will be an invaluable tool for the NPDES program, GIS mapping operations,
planning studies, road, sewer, water and drainage alignment and design studies, police crime scene analysis and police and fire emergency operations planning. The contour data generated from this
project will support all environmental and engineering studies requiring high resolution surface data
using the 2 foot contours.
ENVIRONMENTAL REVIEW:
This is a planning study which is exempt from CEQA under Section 15262 of the California Environmental Quality Act Guidelines.
FISCAL IMPACT:
The cost for the proposed project is $156,000 ($137,034 for the contract plus $18,986 for contingencies). The project costs are to be shared equally between the General Fund, Wastewater Enterprise Fund and the CMWD Water Enterprise Fund. Staff recommends appropriation of funds in
the amount of $52,000 from each of the following accounts: City Council Contingency Account, Wastewater Enterprise Fund Balance and Water Enterprise Fund Balance. Though no detailed financial analysis was prepared, it is expected that most if not all of the project costs will be recovered over the next five to ten years through the elimination of aerial and topographic surveying work for individual Capital Improvement Program projects and studies.
EXHIBITS:
1. City of Carlsbad Resolution No. 200 lc /30 approving a consultant agreement for
professional surveying and mapping services with Merrick & Company, a Colorado
Corporation to provide digital aerial mapping and two-foot contour data of the City and
appropriating funds.

A project ‘kick-off” meeting will be held between Carlsbad, partner agencies, and
Merrick to review all technical and administrative aspects of the project. This meeting
will be a “hands-on” workshop to facilitate the exchange of quality information.
Before the “kick-off” meeting, Carlsbad will be provided a list of items that will be
discussed and finalized at the meeting. The specific topics to be addressed include:
Review the proposed flight and ground control scheme and modify as necessary to meet
project requirements
Develop a conceptual ArcInfo database design, inclusive of any metadata attributes that
will be assigned to the DTM, contour, and ortho imagery databases
Discuss/review tiling requirements (2000 x 3000’)
Review positional accuracy requirements
Define the location of the prototype areas
Determine acceptance criteria for all deliverable products @TM, Contour and digital
imagery)
Identify points of contact and develop communication protocol
Develop status report requirements
Demonstrate the use of Contractor’s secure Internet web site and how it will be used to
help review and monitor project progress and status
Review invoicing procedures
A goal of this meeting is to assist Carlsbad to understand the scope of work, Merrick will
present data from a similar ArcInfo project.
Following the “kick-off’ meeting a detailed memorandum will be forwarded to Carlsbad
project manager to clarify and document the decision/discussion items of the “kick-off’
meeting. Once the memorandum is finalized, it will be posted on the secured Internet
project site.
rev. 4/24/00

Project Setup
1. In order to prepare the initial start up documentation, all of the action items identified during
the “kick-off’ meeting will be resolved.
2. Merrick’s project manager will develop internal, project specific documentation as a
reference for the production staff. This Project Summary outlines the scope of work, project
specifications, deliverables, project schedule, technical procedures, and the quality assurance
plan.
3. During this step, we will prepare the production facilities for the project. The primary tasks
being integrated in preparation of beginning the project are:
n Scheduling of resources (equipment and personnel)
n Customizing in-house software tools, as necessary
n Flow charting the unique production process
n Developing project specific QC checklists for each department
4. A project of this magnitude requires a start-up period of approximately two weeks. Once the
information is gathered and/or tested, the team is ready to begin the next step of the project.
5. Once all of the project startup meetings are completed, Merrick’s project manager will hold
an internal “kick-off’ meeting to disseminate all of the required project information to the
technical leaders that will be working on this project. As an option, Carlsbad can attend this
meeting. Having a representative from Carlsbad office present for this meeting is an
effective way to be sure that the client’s goals and objectives are presented.
Surveying Support for the Photo Control
1. 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.
3. Merrick’s GPS control will be referenced to not less than two survey points. Based on
this approach, there will be 19 photo-identification (photo-ID) points in and around the
Carlsbad area..
rev. 4t24tOO
-20 -
4. Because the ABGPS technology provides X, Y, Z coordinates for every exposure; the 19
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 l”=lOO’ 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.
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. 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.
3. Next, each photo-ID point is “pin-pricked” and fully described on the back of the contact
print. 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.
Acquire New Aerial Photography
1. The project wide negative scale for the color aerial photography will be 1:7,920 (1”=660’).
Merrick will utilize Continental Aerial Photo, Inc. (CAP) to perform the photography
mission. CAP’s 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:
l Flying under optimal weather conditions such as cloud coverage and sun angle
l Federal Aviation Administration (FAA) and Civil Aeronautics Board (CAB) safety
regulations
l State-of-the-art film processing
3. A current USGS camera calibration report meeting specifications for focal length (153 mm,
k3.0) will be provided to Carlsbad.
l All flight lines will be straight and parallel
l Individual exposures must meet the tip, tilt and crab standards
rev. 4/24/00

4. The following photography characteristics apply:
Negative Scale: 1” = 660’ (1:7,920)
Mapping Scale: 1 ” = 100’ (1:1,200)
Contour Interval: 2’
Flying Altitude: 3,960’ above mean terrain
Forward Lap: 60%
Side Lap: 30%
Area per model: 225 acres
Number of Exposures: 270
Mapping Flight Lines: 14
Mapping Flight Line Miles: 115
Mapping Flight Line Direction: North/South
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.
6. The aerial photography will extend a minimum of one half mile out from the City’s terrestrial
boundaries.
7. 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.
Airborne GPS Photo Control and Post Processing
Menick 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. 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 Met-rick’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
Carlsbad.
3. 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.
4. 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.

rev. 4/24/00
5. The latest available geoid model shall be used to determine the separation between the
geoid and the ellipsoid.
6. Quality control will be performed by having loop closures through multiple base stations.
7. 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).
Fully Analytical Aerotriangulation (F’AAT)
1.
2.
Fully Analytical Aerotriangulation (FAAT) creates coordinates (X,Y) and an elevation (2)
for supplemental photogrammetric points on each photograph that are used in the stereo
model orientation process (Model Setup). The FAAT process simultaneously corrects image
displacement caused by earth curvature, atmospheric refraction, camera lens distortion, and
aircraft (flight) inconsistencies. The FAAT process includes the following steps:
= Analytical Point Preparation on contact prints
n Control Point Transfer (Pugging)
n Point Measurement on Zeiss Pl Analytical Stereoplotter
= Process Aerotriangulation and Review Residuals
= Prepare Aerotriangulation Report
A comprehensive FAAT report of the results of the FAAT adjustment will be submitted to
Carlsbad’s project manager. This report will include at a minimum the following:
n A narrative summarizing the aerotriangulation process, results and any steps taken to
resolve misfit control points, if any
n Root Mean Squared (RMS) error and residuals of all control points in the final block
adjustment (with and without check points)
n List of all final coordinates and associated point numbers
= Diagram of stereo model layout with photo centers and control points
This report will be inspected and signed by Merrick’s project manager, Certified
Photogrammetrist, and FAAT analyst.
Develop the Project GIS Database Definitions
1 Merrick, Carlsbad and SDCWA shall create an ARCinfo database design that meets the
requirements of all the participants.. The physical design is intended to create an ArcInfo
and coverage structure that complements the photogrammetry methodology while
considering only the basic application requirements of the users. That is, this design is not
intended to be applications oriented.
2. Upon completion of the prototype project (see below), Menick will follow up with a
rev. 4/24/00
-23 -
prototype evaluation meeting. During this meeting, Merrick will revise the database design
and feature compilation based on the results of the prototype conversion effort.
Develop Prototype DTM, Planimetric, Topographic, and Ortho Image Databases

described in detail later in this section.
Once a small portion of the photography, survey, and FAAT are completed, Merrick will
undertake a prototype project. The objective of the prototype is to prove the photogrammetric
conversion methodology, validate the database design, and finalize discrepancy escalation
procedures.
The prototype will be a representative sub-set of the entire project. It is important to obtain a
large enough sample of the project to insure most database situations and anomalies are
reviewed. The prototype area will be defined at the project “kick-off’ meeting.
Merrick proposes that the size of the area be four tiles. The proposed area is large enough to
review unique project characteristics and economically complete revisions, if required.
In the prototype phase, a model or test will be created and analyzed to guarantee our
procedures and assumptions are valid.
The primary objectives of the prototype are as follows:
n Validate that the digital orthophotography, topographic and planimetric data products
being generated will meet the Carlsbad Project Team’s expectations.
n Analyze unique “local” characteristics of all the photogrammetric features.
n Produce a working model of the, DTM, 2’ topography, and ortho databases in a “GIS
clean” format. This model can be used by Carlsbad’s Project Team to demonstrate and
communicate the purpose of the project to management and administrators.
n Test the physical GIS compatible database structure. The primary aspects of the design
will focus on defining and documenting important database structure items such as:
l File naming conventions
0 Coverage naming
l Annotation layer definition
l Line and symbol coding
l Attribute definition
l Tile formatting
n Review the compilation criteria for each feature being collected.
n Modify as necessary the communication protocol and response time expectation for
resolving project issues.
n Develop new or modify existing in-house project quality control process which minimize
rev. 4/24/00
-24 -
the time that is spent on inspection of each deliverable product.
n Modify and/or customize existing AML, MDL, and LISP routines and in-house programs
to conform to the unique characteristics of this project. The data will be formatted so it is
compatible with the GIS, CADD, and engineering design systems that the project team
members are using.
n Strengthen the working relationship between Merrick and the Carlsbad Project Team.
Review the Prototype Ortho Imagery, DTM, and Topographic Database
1. The Carlsbad Project Team will have an opportunity to review the prototype and verify
data collection completeness, topology, attribution, and overall image quality. To
conform to the schedule, a prototype review period of two weeks is needed for Carlsbad
review.
2. Upon completion of the Carlsbad review, a post-prototype review meeting will occur to
resolve any outstanding issues.
Photogramme trically Collect the DTM
1. A DTM will be collected by Merrick de Mexico (MdM) to produce the digital contour
databases. The contours interpolated using the following DTM collection methods will
meet ASPRS Map Accuracy Standards.
2. The 3-D DTM is formed by collecting breaklines and mass points throughout each stereo
model. Breaklines are collected along abrupt changes in the terrain such as road edges,
drainages, and ridgelines. Mass points are essentially individual spot elevations. They
are observed at pre-defined grid locations, and other strategic locations as required, to
support the accurate generation of contours.
3. Merrick recommends that the grid spacing of mass points be related to final map scale
and contour interval. The following table illustrates the contour interval and DTM by map
scale:
Actual grid spacing and point density depends on the type of area being modeled (rural,
urban, etc.) and degree of relief change. Men-i&s DTM and contouring procedures have
been verified by field survey and are frequently used to generate plan & profile sheets,
road/sewer designs, drainage studies, and volumetric computations.
rev. 4/24/00
-25 -
4. Merrick creates the DTM in four standardized steps.
n Collect 3-D discontinuity lines along all terrain breaks, such as road edge, curb step-ups;
knobs; major road crown; drainages, ridges, etc.
H Elevation profiles are created in parallel rows on each stereo model at pre-defined grid
intervals based on the scale of photography.
n Stereo digitize spot elevations of all high-low points, such as toe and crests, saddles,
buttes, street intersections, and all other operator defined locations as required to meet
final contour accuracy specifications.
n Create obscurity lines (closed areas) where terrain data may be obscured by dense
vegetation or shadow
5. 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 114 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 to economize later processing.
A minimum of three breaklines is 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 modem contour
interpolation programs, the basic character of the ground is determined from breakline
collection.
The top and bottom of retaining walls and major crowned of roads are collected as “hard”
breaklines. Breaklines are not collected on roads wider than three lanes.
Crests of hills and bottoms of valleys should be covered by breaklines unless they are
very gently rounded. These are typically referred to as “soft” breaklines. In heavily treed
areas where little scan data can be collected, a few basic estimated breaklines will help
“hold down” the terrain model.
When collecting breaklines, care is taken so that they do not cross or conflict with other
breaklines or 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 more
accurate and aesthetically pleasing 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.
6 The accuracy and completeness of terrain model is verified using Merrick’s proprietary
rev. 4/24/00
-26 -
software to inspect that scan lines conform to the prescribed accuracy standards (row spacing,
completeness, extent, point density, etc.).
7. The final DTM data will be delivered in an ASCII format that is used specifically as input
into ARCJNFO. The raw DTM data will also be delivered in an ASCII format file to
facilitate the use of a common set of terrain data by engineering companies that do not have a
GIS system.
Create Topographic Databases

7.
The topographic data is built and edited in the MicroStation environment for initial editing.
A series of manual and automated QC steps are completed to ensure the content and integrity
of the compiled data. The data is subsequently translated to ArcInfo for additional editing
and attribution.
Merrick utilizes SiteWorks software to process the photogrammetric DTM and interpolate
the final contours. SiteWorks is an engineering software package that works within
Intergraph’s MicroStation environment.
The grid points from the DTM data set are related and connected to each other by creating a
Triangulated Irregular Network (TIN). Connecting the compiled or interpolated vertices of 3-D
triangles creates the TIN.
When the grid points and breaklines are collected in a sufficient density, the legs of the
triangles that connect the points will accurately represent the surface of the terrain. The
triangles that are created to make the TIN are “drawn” within the contour interpolation (CIP)
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” under ridges or “bridging” over drains.
The next step is to process the DTM data and create the contours. After processing, attributes
for elevation and line type are automatically populated for each line. Contour lines will be
interpolated across sheet (tile) edges to form a continuous line. The sectionalized tile layout
will be used to clip continuous data into individual tiles.
Creating an aesthetic cartographic contour map is the next step in the process. At the editing
workstation, contours are smoothed and enhanced, but within the tolerances of the accuracy
specifications.
-27 -
rev. 4/24/00
8. A final inspection of the vertical accuracy is then performed by comparing the spot elevations
to the interpolated contours. This essential, quasi-independent validation proves the accuracy
of the contours relative to the adjustment of the aerial photography.
9. Merrick utilizes in-house GIS software tools to programmatically create topologically correct
coverages, validate edgematching, annotates 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 is essential to Carlsbad for a successful
project.
10. All final processed graphic data will conform to the following standard GIS topology “rules”:
Edgematching: All digitized features will be both visual and coordinate edge matched
with features from existing data, adjacent tiles, sheet edges, and at model breaks or other
artificial boundaries within a tile. No edgematch tolerance willbe allowed. Attributes
for adjoining features will also be identical.
Common Boundaries: All graphic features that share a common boundary, regardless of
digital map layer, will have the exact same digital representation of that feature in all
common layers.
Point Duplication: No duplication of points will occur within a data string.
Connectivity: Where graphic elements visually meet, they will also digitally meet. All
confluences of line and polygon data will be exact mathematically; that is, no
“overshoots,” “undershoots,” “ offsets” or invalid “pseudo nodes will exist. Lines that
connect polygons will intersect polygons precisely; that is, every end point will be an
intersection point of the respective polygon.
Line Oualitv: A high quality cartographic appearance will be achieved. Transitions from
straight line to curvilinear line segments will be smooth and without angular inflections at
the point of intersection. The digital representation will not contain extraneous data at a
non-visible level. There will be no jags or hooks or zero length segments. Curvilinear
graphic features will be smooth with a minimum number of points. When appropriate,
line-smoothing programs will be used to minimize the angular inflection in curvilinear
lines. Any lines that are straight, or should be straight, will be digitized using only two
points that represent the beginning and ending points of the line.
Segmentation: The digital representation of digital elements will reflect the visual
network structure of the data type. An element will not be broken or segmented unless
that segmentation reflects a visual or attribute code characteristic or unless the break is
forced by database limitations.
Area and Polvgon Closure and Centroids: For area features being digitized, the last
coordinate pair will be exactly (mathematically) equal to the first coordinate pair.
Centroids will be placed in all polygon area features.
Point Criteria: All point features will be digitized as single x, y coordinate pairs at the
rev. 4/24/00

visual center of that graphic feature.
Final Quality Inspection of the Topographic Data
1. Thorough quality inspection procedures will be incorporated during each phase of the
conversion process, thereby minimizing the amount of quality inspection required at this
stage.
2. Merrick will verify that the GIS compatible database conforms to the following
specifications:
n Coverage tolerances and name (dangle nodes, pseudo nodes, projection, arc direction)
n Item definition and user defined attributes (field length, data ranges, completeness)
n Annotation subclasses (i.e. $symbol, $level, $size, $offsetx, $offsety, $justify, and $fit)
Digital Orthophotography Image Processing
The following is an overview of the process by which Merrick creates digital orthophoto images.
There are six main steps involved in creating a digital ortho. These include the following:
n Creation of the DTM
n Negative rasterization (scanning)
n Fully differential orthometric rectification
n Radiometric correction and image processing
n Data quality inspection and delivery
n File compression
Each step of the production process has internal validation measures, which must be approved
before proceeding to the next step.
The major components of each step are outlined below:
Film Scanning
a. The original film negatives are converted to raster color images using the Zeiss SCAI
film scanner. Scanning the original (first generation) negative creates a higher quality
image than when scanning a diapositive.
b. When handling the original aerial film, Merrick’s scanning analysts use extreme care
and wear protective gloves. This procedure reduces the possibility of scratching.
c. When scanning the film, 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 color.
rev. 4/24/00
-29 -
Digital Ortho Rectification
1. Once Merrick’s photogrammetrists verify the DTM, the point data is resarnpled to an
even multiple of the project pixel resolution for more efficient processing. Merrick uses
Zeiss OP utilities to complete this phase of processing.
2. Establishing or defining the ground surface and scanned negative relationship via digital
orientation are the next steps in the process. During this process, digital images are geo-
referenced to the DTM surface through 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.
3. Merrick uses a suite of Zeiss digital image rectification and processing software packages
to rigorously calculate and generate precision ortho data from the original scanned
negatives. Merrick will use a Cubic Convolution re-sampling 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.
4. The relationship between each photo and the camera, as well as between the camera and
ground is used to precisely model and modify digital image geometry. This allows
correcting for image distortions introduced by camera tip and tilt, terrain relief
displacement, film deformation, lens aberrations, earth curvature, and atmospheric
refraction.
5. Using high-powered workstations and Stellacore OrthoVista software for image
processing, the radiometric characteristics of each image are automatically compared and
adjusted to a standard project histogram. This results in each ortho being processed with
similar tonal quality throughout the entire project area.
6. Before delivering the orthophoto products, rigorous inspection of each image is
performed by displaying each image and the surrounding images on screen. Mismatches,
DTM “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.
Digital Mosaic for Seamless Imagery
1. Merrick will use an advanced digital mosaic approach to create seamless ortho imagery over
the entire project area.
rev. 4/24/00
-30 -
Final Digital Ortho Formatting
1. The ortho images will be formatted according to the predefined tile layout. Merrick will
propose the final tile
(2,000’ x 3,000’) scheme and number if tiles once the pilot is delivered.
2. It is understood by Merrick and Carlsbad that full 2,000’ x 3,000’ tiles will be delivered.
3. For this project, we anticipate that all imagery will be output as Continuous Tone, TIFF,
Class G format files with a World File. This format is readable by ArcInfo and other GIS
packages.
4. Following image acceptance, Merrick will compress the data using MrSID compression
techniques developed by LizardTech. Merrick will work closely with Carlsbad to
establish the most appropriate compression ratio(s). Typically, color compresses 50: 1.
