Project Management
Project Planning and Management
Mapcon will appoint Kevin Woolf as the Project Manager to the City of Auburn's
Orthophotography and Planimetric Mapping project. Our process for developing a project plan
begins with a meeting between the Mapcon Mapping Project Manager and the client, the City of
Auburn. At this meeting we confirm the requirements of the project as described in the SOW and
discuss any client-requested modifications. Any critical issues are resolved at this meeting and
addressed in the Project Plan.
We will then develop a written Project Plan for review with the City, to document the following:
• Key production phases and milestones in the project execution.
• Team member roles and responsibilities are documented
• Identification of QC/QA processes for all phases
• Description of deliverables
• Schedule for project reporting and final delivery
• Daily checks on subcontractor progress
We will use e-mail and FTP resources to maintain current lists of the work accomplished, time
spent, materials required for future work, etc.
As the work comes in it will go through our QC department. Daily reports on the analysis of the
data will be generated and sent to the production department. These reports will be used to
identify systematic errors that may come up and ensure that they are quickly addressed and
remedied with a plan to ensure they do not recur.
As production continues an ongoing monitoring process will be used to track the possible errors,
the technicians responsible, and the processes followed. This will be used to plan training
programs to upgrade skills, to adjust QC levels to ensure compliance with standards and
specifications, to plan future QC programs, and to report on past performance.

Methodology
Control Transfer
Due to our project experience in this region we are able to recover existing ground control points
from our previous projects that will reduce the survey costs to the City of Auburn. We have
included a map showing the location of our control and proposed new ground survey points.
Within the existing orthophoto coverage we will extract any City of Auburn control that is usable.
Sources of ground control include:
Pierce County Project
- Within the required project boundary we can recover control point location from our
Pierce project to control the south portion of your project (see attached map)
City of Kent
- Within your required project boundary we can recover targeted control point location form
our City of Kent imagery and stereoscopically digitally transfer this control to the new
imagery and control the northern portion. (see attached map)
City of Auburn
We will control the new photo from both the existing targeted control (80) that are
recoverable and extract supplemental control from your existing controlled orthophoto by
means of a digital stereo comparator method, fully described in our methodology section.
The principal benefit of this technique rests in the fact the new 2007 orthophoto will fit the
existing the City of Auburn ortho coverage within your required accuracy specification.
We recognize that the City has built up an extensive library of adjusted GIS control point
data and that the existing orthophoto represents a valuable source of control data for this
new project.
This data has proven to be of high quality and accuracy. That data represents a significant value
to The City of Auburn and can and should form the basis of control for the aerial photo imagery
from this project. We will use a digital stereo comparator method to select as much control as
required from the existing data sets. Under the complete control of our skilled operators,
sufficient control will be carefully transferred to the new photo using our stereo softcopy systems
in a digital stereo comparator mode. This process will ensure that we have an acceptable fit to the
existing orthophoto.
All control point data and mapping shall be referenced in the Washington State Plane
(North) American datum of 1983 (1991) in English units. Vertical datum shall be the
North American Vertical datum of NAVD88 Adjustment.
New Ground control (photo ID)
- If we require any additional ground control in the new ortho areas we have budgeted for
either establishing new targeted ground control or use of Photo ID points to ensure the
Aerial Triangulation meets the required accuracy.
ABGPS
- Airborne GPS data will be acquired during the aerial flight and post processed to support
the aerial triangulation process.

Aerial Photography
Mapcon will acquire one single compliant spring flight of 1"=400' color imagery with 60% forward
overlap and 30% sidelap under calm, clear atmospheric conditions, when ground is not obscured
by cloud (max 1 % in any photo frame), cloud shadows, haze, snow cover, or flooding. Photo will
also be restricted to times when the sun angle is 30 degrees or greater and vegetation is leaf free
or has minimal growth. Processed film will be annotated with date, scale, project name, flight line
number and exposure number, and will be processed within one week after the flight. We will
notify the City at least 24 hours prior to conducting the actual flight. As part of our Quality
Assurance process, we will submit QA reports on our inspection of the film, and scanned
imagery, as well as aircraft flight logs, current USGS Camera Calibration Report, and final Aerial
Triangulation report, which will document all critical aspects, including whether specified
parameters such as overlaps, crab, scale, and coverage, were met.
This scale of photo exceeds the NMAS horizontal accuracy standards for 1 "=100' scale mapping,
and for NMAS vertical accuracy for DTM and 2 foot contour mapping and can provide a high
quality 0.33 foot color pixel. This option meets all required technical specifications required by
the city.
We will acquire the required aerial imagery utilizing the aerial photo services of GPS Surveying
Inc. GPS Surveying based at Paine Field in Everett WA, within 50 miles of the City of Auburn
project site. GPS Surveying has extensive project experience throughout the Seattle area (see
attached maps in Appendix for photo flight plans).
We routinely design our flight plans with one photo frame overedge, so as to fully cover the
project area with photogrammetric stereo models. Modern GPS-controlled navigation systems
ensure that the aircraft closely follows the flight plan. Airborne GPS data will be acquired during
the aerial flight and post processed to support the aerial triangulation process. Our AT experts
design a flight plan to make most efficient use of the photography, and submit this plan in digital
format to the flying contractor for use in controlling the aircraft during the flight. The flight plan will
ensure that all of the project area is covered with stereo photography. Flight plans, and camera
calibration reports, will be submitted to The City of Auburn for approval prior to the aerial photo
mission. We have included our preliminary flight plans in this proposal. These flight plans will be
finalized at project start-up.
Equipment
Our aerial photo subcontractor for this project is GPS Surveys Inc. based at Paine Field in
Everett, WA. GPS Surveys has many years of experience in acquiring aerial photography
throughout the Pacific Northwest. They have been carefully screened to ensure compliance with
the latest requirements for softcopy photogrammetric processes. All aircraft used by our team are
equipped with Zeiss LMK 2000 cameras (or equivalent) equipped with a Forward Motion
Compensator (FMC) to minimize image blurring during exposure. The AWAR of this camera lens,
as per USGS calibration report (see report in Appendix), is over 100. Cameras are also equipped
with a gyro-stabilized mount that compensates for angular aircraft movements, including pitch, roll
and drift of the aircraft, usually due to turbulence. The size of this project and proximity to Paine
Field ensures that it will be a priority for photo acquisition. Bill Dawson will work closely with GPS
Surveying Inc to make use of all available flight window opportunities, so that the City of Auburn
imagery is captured at the earliest opportunity with suitable conditions.
Airborne GPS will be acquired during the flight. This on-board technology, combined with a skilled
flight crew ensures that the acquisition of project photography will be to the highest possible
standard. The AGPS system can locate the exposure station of each photograph to within 0.5
feet. As well, the current camera calibration report will be supplied for verification of authenticity.
This report is fundamental to the subsequent stage of aerial triangulation, providing the model by
which the camera captures the imagery required for mapping. Post flight reporting includes flight

logs, and the current camera calibration report, which will be supplied to the client for verification
of authenticity. This report is fundamental to the subsequent stage of aerial triangulation,
providing the model by which the camera captures the imagery required for mapping.
Scanning
Upon acceptance of the aerial film, we will then scan the negative roll as per our QA/QC
procedures. Scanning will be performed by our aerial photo contractor, GPSS located in Everett
WA. We will be scanning directly from the negative aerial film rolls, on Wehrli RM-6
photogrammetric scanner. This scanner is equipped with dust and scratch removal software.
This involves two scans for each frame, one scan in IR to define the dust or scratch anomalies,
and a standard color scan. The final product is a scan that is software enhanced to remove the
dust or scratch identified in the IR scan. This process significantly reduces the QA/QC time
required by The City of Auburn. We will utilize the aerial photo sub contractor GPSS for the film
scanning. This will increase scanning turnaround and further mitigate any introduction of film
damage due to unnecessary shipping or handling
By scanning the original negative film roll at the aerial flight contractor site, the chance that
scratches, fingerprints, or other marks will be introduced into the imagery is minimized, and
eliminates the cost of producing diapositives with its corollary effect of image quality degradation.
The scanners are calibrated to a repeatable geometric accuracy of less than 3 microns. Imagery
will be scanned at 12 microns.
Color film will be scanned to 24-bit, three-band color TIFF imagery. Under normal scanning
strategies, automatic scanning of roll feed based films is monitored by software designed to
ensure consistency between image scans. Automatic scanning takes into account the following
steps/tasks:
• Auto determination of scan parameters
• Auto adjustment of scan region according to the recognition of either film edge or fiducial
pattern/shape
• Automatic radiometric adjustment (Auto dodging for negatives)
• Automatic Interior Orientation
• Automatic image pyramid generation
All the automated steps are monitored by the scanning personnel to ensure we obtain the
maximum amount of information possible from the raw film. The operator will adjust the scanning
parameters whenever the automated ones are not meeting this objective.
Quality Control of Scanning
Quality Control is again a critical step in the process of transforming the film negative into a
scanned image suitable for softcopy photogrammetric collection. The quality of scanned air photo
images has a direct impact on the clarity of stereo model when viewed in a digital mapping
environment as well as the quality of orthophoto imagery.
We have developed the following strategy for greatly reducing the occurrence of Newton rings
and other unwanted artefacts in the final orthophoto imagery.
1) The exposed film is processed and scanned by the same company, GSP Surveys. This is
done to completely avoid the possible introduction of dust and scratch due the usual film edit
stage. Since the edit will not have been completed we will base our scan lists on the detailed
flight report kept by the flying firm.

2) The film is cleaned on and HAS cleaner designed specifically for aerial film rolls. In addition,
immediately before being scanned the film and scanner will be cleaned with ionized air for
removal of any dust in the scanning room.
3) Once the scanning has been completed the film will undergo the normal edit stage. At this time
any required replacement frames will be identified and scheduled for reflight.
3) The Wehrli scanner uses a top plate held down with positive pressure. This has proven to be
substantially more effective than other scanners that rely on gravity alone hold the upper glass
plate down. This has been shown to significantly reduce the occurrence of Newton rings. In
addition Mapcon has found that the location in Salt Lake, with its very dry atmospheric conditions,
is also a great aid in reducing the occurrence of Newton Rings.
Incoming scans are subjected to rigorous inspection by the Mapcon Mapping Inc. team for the
following characteristics:
• Radiometric balance across the project area
• Histogram for each frame is examined to ensure that the scan image min. and max.
brightness values are well distributed between 0 (black) and 255 (white) to eliminate any loss
of detail due to saturation or burnout.
• Check image consistency against other images within the flight line, and on adjoining flight
lines
Time has been allocated to remove dust/scratches/Newton rings from the scanned imagery.
Once we have completed scanning, we will ship the aerial film roll(s) in plastic storage canisters
to you.
Aerial Triangulation
Using the ground control we have extracted from our City of Kent and Pierce county projects,
recovery of existing Auburn control points, supplementary horizontal control from the existing
Auburn orthophoto and the Airborne GPS data, we will perform a preliminary AT adjustment. We
will then check the fit of the preliminary AT solution to our ten new GPS targeted ground control
points before generating the final adjustment.
We will generate a preliminary AT report for review by the City before proceeding with the final AT
adjustment.
We propose to carry out a fully analytical AT solution in softcopy mode, using the scanned aerial
imagery, Intergraph's AT software packages (ISDM and ISAT), and Inpho's inBLOCK software for
the final adjustment. The phases of the AT process are described in detail below:
Mensuration
The first stage of the Aerial Triangulation process creates additional photogrammetric or ground
points (minor control) at key locations on the aerial photograph to support setting-up of
photogrammetric models for digital mapping and orthophoto image production. By establishing a
dense network of secondary (or minor) control using AT methods, we avoid having to acquire
additional, expensive control from survey points in the field.
All eight fiducial marks on each frame are measured automatically and used to reference the
individual photo frames when setting up the models for photogrammetric collection. (known as
establishing the "plate coordinates"). The camera calibration report is used to model minor
deviations specific to the camera/lens combination being used. Minor control points, consisting of
strategically positioned pass and tie points (common points on adjoining photo images) are
selected from within the central portion of each photograph. These points are coded with a unique
number in accordance with their position on the photograph and their location in the block. Minor

control points may include paint markings on paved roads, corners of structures and other clearly
discernible features that will permit precision measurement. These minor points are collected in a
stereo softcopy environment, a process known in the industry as digital mensuration. Additional
points are mensurated on shorelines of hydrographic features to ensure that lake surfaces will be
level and that watercourses maintain a correct directional flow.
There are two basic approaches to collecting minor control- purely manual and partially or fully
automated. We plan to use as much of the automated approach as possible but we expect that a
combination of the methods will be required. The decision as to the approach used is based on
the input imagery's suitability to the process. The determining factor is ensuring that the method
selected will provide the required accuracy levels based on the specifications for the project.
The semi-automated approach involves operator-guided selection and measurement of the data.
There are normally 9 to 20 pass and tie points generated by this method. The automated
approach is a purely automatic approach only requiring manual intervention once completed, to
ensure sufficient quality points are generated in the required areas. There are normally 50 to 100
pass and tie points per frame generated by this approach.
The automated approach has the advantage that its large number.of points per frame allows for a
higher redundancy, which in turn allows for more robust automated blunder detection algorithms
to be used. This can result in much shorter analysis times being required for the block adjustment
even though there is more data to evaluate. The automated correlation routines can be fooled by
situations such as shadows falling in different locations on adjacent frames due to differing flight
times resulting in different sun angles. They can also fail in areas of low tonal variation resulting in
weak areas. These situations have to be manually mensurated. Manual inspection by an
experienced photogrammetrist finds and corrects these problems.
AT adjustment
The second phase builds on the mensuration stage described above and performs a block
adjustment on the plate coordinate file using Inpho inBLOCK bundle adjustment software. The
software has sophisticated features such as automatic error detection, airborne drift correction,
self-calibration and graphical viewing tools.
Using advanced numerical algorithms, the block adjustment creates ground coordinates in X, Y,
and Z for all points. As a precursor to photogrammetric collection, these points will be used to set-
up the photographs with the identical orientation (roll, pitch, and yaw) that was present in the
aircraft at the time the aerial photography was flown. A senior AT technician evaluates preliminary
results and assigns a "weight" to each point based upon its reliability and importance to the
adjustment. Selected points read from existing sources of horizontal and vertical control will be
assigned the highest weight based on their reliability, while the mensurated minor control points
are weighted at a lower importance. Expertise gained over many hundreds of AT projects plays a
crucial role in ensuring a proper weighting and analysis of every point.
After adjusting the weights, the Inpho inBLOCK software calculates the best fit of each point and
adjusts the entire block in a series of iterations. inBLOCK outputs a comprehensive statistical
summary as part of the AT block adjustment. This statistical summary, in combination with
sophisticated graphical viewing tools, is used to analyse the results.
The ultimate goal in the AT adjustment process is to generate an average residual value that is
below the threshold of the minimum accuracy requirement. inBLOCK identifies any point that
exceeds the threshold, possibly due to errors inherent in the process. These are corrected prior to
the final adjustment.
The final product of the Aerial Triangulation process includes a set of adjusted coordinates and
exterior orientations for all of the photography, plus a set of orientations for each frame in the

adjustment. This information is used to properly orient the stereo models for data collection
(compilation) with SoftCopy stereoplotters, and for orthophoto production.
Additionally, on completion of the AT adjustment we generate a final AT Report, containing a
summary of procedures used, including block adjustment statistics and a statement on the
estimated accuracy of the block. The aircraft camera calibration report is also included.
Digital Terrain Model
Mapcon will collect a totally new DTM surface which includes DEM elevation points, planimetric
ground features and topographic breakline for purposes of orthorectification and for the
generation of 2 foot contours. The DEM will be supplemented by custom photogrammetric
breaklines (bridge, overpass and elevated roadways) to be utilized in the orthophoto process to
correctly represent any above ground features.
A DTM is composed of breaklines and mass points. Breaklines are three-dimensional linestrings
digitized along significant breaks, or changes in the topography, such as ridges, drains, retaining
walls, cliffs, highway cuts and fills, and sharp slope changes. Crowns of roads and railroads as
well as streams, lakes and other such features can also be collected as breakline features. Soft
breaklines may also be captured from the top to bottom of a hill.
Mass points represent terrain elevations for ground positions at regularly spaced horizontal
intervals on the earth's surface. Mass points can be collected from the stereo imagery under
complete control of a photogrammetric technician, or by automated methods using
autocorrelation of common terrain points in adjoining frames. Exclusion boundaries are set up to
constrain or suppress terrain modelling in regions of common elevations such as lakes.
The final TIN is used to generate the contours and as the base for the orthophoto rectification.
The TIN model represents the terrain surface as a set of contiguous, non-overlapping triangles.
The vertices of each triangle are comprised of mass points and breakline points and the triangle
surface is represented by a plane. Contours are then interpolated through the TIN and normally a
spline is applied to the output line in order to cartographically enhance the appearance of the
contours.
QC procedures are used to verify that the DTM model accurately captures the ground surface
characteristics. A comparison of the DTM masspoint elevations against the minor control points
from the Aerial Triangulation process is undertaken to confirm that no anomalies have been
introduced. A visual analysis of the DTM as a grayscale shaded-relief image ensures that the
coverage is continuous and extends slightly beyond the mapping project area. Any spikes or
other anomalies are easy to spot with this method.
The TIN can also be used to generate a regularly-spaced grid of elevation points, sometimes
known as a Digital Elevation Model (DEM), which has 3D modelling uses.
DTM data can be delivered in numerous formats, including AutoCAD dwg, DXF, Microstation
Agn, and ESRI Shapefiles.
Our QC will verify that the DEM model accurately captures the ground surface characteristics. A
comparison of the TIN against the minor control points from the aerial triangulation process is
undertaken to confirm that no anomalies have been introduced. A visual analysis.of the TIN as a
grayscale image ensures that the coverage is continuous and extends slightly beyond the
orthophoto project area. This ensures that orthorectification will be complete and accurate to the
limits of the project boundary.

Two-foot Contours
We will extract all appropriate planimetric surface features, recode them to breaklines, and merge
this data with the DEM collection to create a TIN surface. The TIN model represents the terrain
surface as a set of contiguous, non-overlapping triangles. The vertices of each triangle are
comprised of mass points and breakline points and the triangle surface is represented by a plane.
This TIN surface is also utilized for the ortho rectification process. From the TIN, we will
automatically interpolate two foot contours with operator controlled annotation at 10 ft intervals on
the index contour lines. Annotation shall not obscure significant terrain features. Depression
contours will also be shown as our test of the methodology described above yielded an
acceptable quality contour surface. All line work will be snapped, nodded and edge matched and
all complex lines will be dropped. Our contour pricing proposal includes a basic level of
smoothing and annotation. If additional smoothing or cartographic editing is required by the City,
this can be executed for an additional fee. The City will approve of the smoothing algorithm and
process in advance of the contour generation.
Contour data will be delivered on DVD-ROM discs in ESRI shapefile format.
Orthophoto Production
The quality and utility of an orthophoto data set is largely dependant on proper project planning.
Our Project Manager consults with the client to define a Project Plan, which documents the
client's requirements and sets out clear, identifiable steps that will lead to the final deliverables.
We establish a QC plan to ensure that the required steps are followed and supported by auditable
documents. All source materials required for the project will be assembled prior to project start up
and assessed as to suitability for purpose.
Our orthophoto production process incorporates every frame of photography into the final
orthophoto image base. In this way, artefacts resulting from optical and radiometric distortion,
including such issues as building lean, as well as tonal contrast between contiguous features on
adjacent frames, can be avoided or mitigated by having the full selection of imagery available for
use. Color balancing and spatial accuracy of orthophotos will established during the pilot phase
and will presented to the City for approval. We have provided for 0.33 foot pixel seamless color
orthophotos as defined on the enclosed 1=400' scale flight plan flight plan, All data will be tiled to
the City of Auburn desired grid.
As mentioned in our section on DEM collection above, we will collect breaklines at bridge decks
and along raised roadways in order to ensure that these above ground features are orthorectified
in their true position in the final orthophoto imagery. Without this additional attention to the DTM,
above ground features would be subject to "layover" and would be incorrectly positioned in the
final imagery.
Orthophotos are rectified with Intergraph's Ortho Pro, using the "cubic convolution" algorithm,
which is superior to "bilinear" or "nearest neighbour" techniques. Rectification of large batches of
frames is preferred for consistency of image processing. The rectified images are radiometrically
adjusted on a frame-by-frame basis to ensure consistency of tone and contrast, although
preliminary adjustment at the scanning phase will greatly reduce the need for significant
adjustment at the orthophoto stage. Shadowed areas are inspected on the rectified imagery and if
required, an auto-dodge process is applied to the rectified imagery to improve image clarity within
these areas.
Software is used to generate a "best path" mosaic line solution, and the orthophoto technician
can manually override the software solution to ensure that buildings and other man-made
features are not sheared by the mosaic line. Mosaic lines ideally run along the edge of fields or

watercourses to minimize any visual impact. Feathering of the mosaic lines also helps to
minimize any discontinuity by subtly blending one image into another.
The technician checks for image distortion or smearing of elevated features such as bridge decks
and makes local adjustments to the imagery as required. Any final radiometric adjustments are
made as a result of detailed image inspection by an orthophoto technician. In the final orthophoto
imagery mosaic lines are practically invisible and sheets can be tiled together without the
distraction of visible sheet edges. The entire mosaic is then cut into the desired tile layout. All
media output is validated to ensure data integrity in the final product.
Orthophoto QC procedures
Geometric Accuracy Checks
One of the primary goals of this project is to produce updated orthophotos that will geometrically
match the locations of the existing image data base. This is necessary in order to ensure that all
of the existing coverages that have been carefully aligned to the existing imagery will line up
within the specified tolerance on the new imagery set.
In order to achieve this goal there are some fundamental production requirements we will follow.
• Generate ground control point locations from the existing imagery to act as primary
control for the new aerial triangulation that are common to and consistent with the
existing data
• Use a DEM that is of equivalent accuracy to the one used to produce the existing
data
• Carry out orthophoto rectifications according to documented procedures
• Check that all the above have occurred and the resulting new orthophoto imagery
matches the locations of the old imagery
We have described the methodology for the first three points previously. In order to be able to
verify that the resulting product meets the specification we propose to carry out the following
procedures.
1. Check Points
Once the orthophotos have been completed we will use in house written software in
conjunction with our VROne Mapping Software to read the location of Check Points
(CP). In order to be not only statistically significant, but also to be certain of the
confidence the City can take in the result we plan to read a very large number of
points. We are proposing to read two points per section which will result in a total of
1420 check points.
We will predetermine the location of the points based on dividing the section in two
halves, east and west. One point will fall in the center of each half. If the City would
prefer we are quite willing to have the City predetermine the locations for the CP's. In
this case the City would provide us with a Shape file showing the required positions
to the CP's.
These CP's will be read in areas where the ground is not obscured by vegetation,
buildings, parked cars, etc. All CP's will be located at ground level. This is necessary
to ensure that there is no displacement caused by the height of ground on a feature
such as a building rooftop.
A discrete clearly identifiable surface feature will be selected. Examples of such
features will include but not be limited to:

• Painted lines on roads and parking lots
• Intersections of sidewalks and driveways
• Manholes and catch basins
• Fence corners in rural areas (these are potentially less reliable features
and will only be used in the absence of clear features
2. Measurement Procedure
The new and existing imagery will be displayed simultaneously in adjacent window.
The windows will display the geographic region at the same scale. The operator will
be automatically prompted to read the location of the point in each image set. If the
operator determines that the predetermined location is unsuitable as per the criteria
in item one above then they will be allowed to move to a location within a 300 foot
circle of the predetermined position.
The software will record a point at the measured location in each data set in a
separate Shape file. In addition the points in the New Shape file will have the
following attributes assigned:
Delta _X - This will be the difference in X in ground units between the old and
new
Delta_Y - This will be the difference in Y in ground units between the old and
new
Delta_XY - This will be the difference in XY in ground units between the old and
new
3. Analysis and Reporting
On completion of the above Quality Checks the operator will flag any CP's that have
differences greater than the specification. The Orthophoto Supervisor will then be
tasked to investigate the cause. If it is possible to correct it the orthophoto will be re-
rectified. If the cause is determined to be an error in the existing orthophoto we will
report this to the City and seek guidance on how to proceed.
Any orthophotos that are recreated will have the measurements of the CP's redone
and a new Shape file generated.
Once all the internal Quality Control analysis is complete a report will be produced
that will summarize the results both in a written form as well as in a plot of the errors.
This will identify if there potentially are any systematic problems.
Radiometric Balancing Checks
The Radiometric Balance of the image refers to the degree to which the resultant imagery
appears to be realistic in color, smooth in gradation, and consistent across the entire
project. It is a requirement that the finished orthophotos appear as seamless and
continuous as possible.
As the overall City will be covered by hundreds of photographs there are radiometric
variations created in the imagery that are a result of:
• Illumination conditions
• The time of day the image is captured
• The time of year the image is captured
• Atmospheric conditions
Mapcon Mapping Inc. Company Confidential 13
Orthophotography & Planimetric Feature Collection,
City of Auburn, WA
M A iF3 C O N
M A P P I N G I N C.
• The level of haze present in the atmosphere (there is always haze)
• The level of humidity in the atmosphere
• The presence of clouds
• Lens
• The focal length of the lens
• The type of lens
• Radiometric filters used
• Anti-vignetting filter use
• Film or Digital Sensor type
• Manufacturer
• Film/sensor type
• Emulsion number
• Storage and handling
• Processing
• Flight Line
• Adherence to the predefined photo centre locations
• Maintenance of appropriate overlaps between frames
• Scanning (if film based)
• Manufacturer
• Scanner setup
• Scanner illumination
• Scanner filtration
• Scanner sensor
The sum of all the above can be referred to as the optical system. Each one is affected
by the conditions/choices made higher up in the list. We have selected aerial
photography acquisition and scanning firms (Mapcon) that have state of the art
technology and a solid reputation for maximising the quality of the photography.
To ensure that the imagery is up to standards we will carry out quality checks in each of
the above areas. However it must be noted that there will necessarily be areas where the
imagery is less optimal for reasons beyond the control of the photo and scanning firms. In
these situations we will take corrective actions on the resulting imagery to minimise these
effects.
A standard mosaiced image from the pilot project will be used as a reference throughout
production to guide the production staff in acceptable color, tone balance, and
consistency. The mosaiced images will be reviewed at both large (1:600) and small
(1:24,000) scales to verify that the overall tone is consistent throughout the project. The
viewing at smaller scales is also important to verify that the level of image dodging was
sufficient to ensure there is no "patchwork quilt" effect.
Image Artefact Checks
Image artefacts are defined as anything in the optical processing that physically obscures
the imagery as presented to the camera at time of exposure:
• Film processing residue
• Scratches in the raw film prior to scanning
• Dust or hair on the film at the time of scanning
• Newton Rings caused by the scanner
• Pixel dropouts during scanning
Mapcon Mapping Inc. Company Confidential 14
Orthophotography & Planimetric Feature Collection,
City of Auburn, WA
M A P C O N
M A P P I N G 1 N C.
We are planning to use the newest scanner on the market which implements a scratch
and dust removing algorithm that will ensure the resulting imagery is free of such
artefacts. This scanner has also been shown in repeated practice to not create Newton
Rings. This is the only reasonable approach to Newton Rings for once they are in the
scan they are extremely time consuming to remove and at best are typically just reduced
in intensity.
We will do a check of five per cent of the raw scans as they are received BEFORE the AT
starts to ensure the scans are up to standard. If all the checked images pass the scans
will be accepted. If ANY fail then the entire batch of scans will be rejected and rescanned.
We will do also do a one hundred per cent check of the orthophotos to ensure the final
product meets specification. This will entail viewing the ortho image at a scale of 1:1,200
a tile at a time. A QC log will be kept for every tile and submitted with the tile.
Mosaic Checks
The mosaic between frames is an area where as a result of the imaging process there
WILL be differences in perspective, geometry, and radiometry. The goal of the production
process is to keep these within specification. The goal of the mosaic check is to identify
areas where there are residual problems that exceed specification and return the tile for
corrective action.
Checking the seam line location in terms of perspective is carried out to ensure that the
degree of radial displacement is kept to an acceptable level. It also checks for problems
with seam lines passing through buildings inappropriately and causing it to appear as if
two buildings lean in and touch each other. These checks are carried out by operators as
they pan through all the image tiles. As we define the seam lines their location is stored in
a vector format that will be provided to the City as Shapefiles.
Similarly it is relatively easy to verify the geometric accuracy along the seam line. By
panning across the image with the seam lines superimposed the operator can quickly
places where there is a mismatch that exceeds specifications. These will be returned to
production to correct prior to submission.
Planimetric Data collection
We are offering photogrammetric 3D collection of all the required planimetric features as per the
feature list as described below. This data will be digitized directly from the new aerial triangulated
imagery according to The City of Auburn accuracy and data structure specifications. As a value
added feature we will attach a roofline elevation as an attribute at no additional cost to the City.
Our photogrammetric staff is trained to collect information according to client specifications. At the
outset of the project, our Project Manager will meet with the photogrammetric supervisors to
review the client requirements as set out in the project plan. All project staff are made aware of
the project requirements and are assisted in this task by a specifications database unique to each
project.

Data Editing
Requirements for data structuring, including line noding, polygon formation and definition of
polygon centroids are defined as part of the project plan. These specifications take into account
the client's GIS requirements for topology and are designed to ensure that the final delivered data
integrates into the existing GIS structure. Any additional feature attributes (unique coding of
feature characteristics etc.) requested by the client are documented in the project plan.
Metadata requirements also need to be addressed in order to provide full documentation on data
progeny, accuracy of source information and unique data characteristics. Metadata is collected at
the feature level as well as the file and project levels. Each level in the hierarchy has unique
metadata requirements and issues that together provide complete understanding of the project
data. Data collected will be editing in MicroStation and edge matched to the existing data where
possible.
The project plan also defines the procedures that will be used to QC the final data. This will
ensure that all data is subjected to rigorous and consistent review prior to being released to the
client.
A number of critical QC steps are undertaken to verify that the final map data complies fully with
the standards and specifications as set out in the project plan. These include:
• Check for coverage
• Check for structuring errors (i.e. ensure streams flowing downhill, lakes are planar)
• Confirm correct directionality of polygons
• Proper noding according to feature hierarchy
• Overshoots, undershoots, data spikes
• Sliver polygons
• Common boundary coincidence between two features based on mathematical coordinates
• Check of attributes and correct centroid placement
• Check for completeness of contents

Lynnwood, WA 98037
(425) 742-8205
Greg Sykes is a Registered Professional Surveyor in the State of Washington (Licence # 21680)
GPS Surveying, Inc., of Lynnwood, Washington, uses aircraft equipped with precision airborne
real-time kinematic DGPS systems, a Zeiss LMK 2000 camera, equipped with Forward Motion
Compensation (FMC) and a 6" lens. This system can control the path of the aircraft and timing of
exposures, exposure camera stations are normally within 100 feet of the planned photo center.
This means that the actual flight plan should not vary visibly from the original flight plan. After the
flight, the recorded exposure stations will be checked to ensure that this is the case. A report of
the final GPS positions will also be submitted.
Turbocharged Cessna TU206F
This aircraft is equipped with extended range fuel tanks that can span an 8 hour photo flight, if
necessary, allowing us to fly during an entire "flying window" without having to land, refuel and fly
back to the site. This is an extremely useful advantage when flying photography for orthophotos.
This allows us to maximize the number of photos taken during a given "flying window" providing a
better match of exposure, sun angle, same lighting and atmospheric conditions between frames.
Zeiss LMK 2000 mapping camera
This camera is equipped with forward motion compensation and is mounted on a gyro-stabilized
mount. This provides a very stable platform for photography, even in turbulent air. The mount
keeps the camera level for both pitch and roll, which provides a more uniform overlap and no side
motion if the plane rolls in turbulent air. The camera has a recent calibration from USGS in the
year 2000 and was calibrated with 2 film magazines. The camera can be triggered by a computer
at a given distance between frames, setting the interval to trigger at a given overlap, or at
predetermined individual photo centers by coordinate.
Trimble GPS Receivers (4)
Accurate positioning of the aircraft is essential for AGPS applications. We record data at a %s
second recording rate, using Trimble 4000 SSI dual frequency GPS receivers. Each receiver has
an expanded memory to be able to record 6 or more satellite data over long periods of time,
which will accommodate a flight throughout the "flying window".
Trimble GP Survey software
Trimble's "GP Survey" is the most widely used GPS baseline processing software. This software
is also used for processing the AGPS data.
Geolab GPS adjustment software
This software allows us to incorporate GPS vectors from the ground control with the AGPS data
to strengthen and insure the best possible fit for the aero-triangulation. The least-squares
adjustment allows us to detect any discrepancies within our control and also to the horizontal and
vertical constraints of the networkSubcontractors

Appendix 4 - Maintenance
The City has requested that we include a maintenance plan for the City's orthophoto and
planimetric data set. Mapcon Mapping recognizes that the City of Auburn is making a
significant investment in data infrastructure through the execution of this contract. As a
result, there is a need to protect this investment through establishment of an ongoing
data maintenance program that will ensure that future data updates are carried out with
maximum efficiency and provide best value to the City.
Our experience with other City and County clients is that due to the scattered nature of
change, a refresh cycle of two years for the entire orthophoto data has become the
common standard.
The topographic data (DTM and contours) will require minimal updates in areas where
DTM change would cause orthophoto errors. It would not require a full systematic
update until at least the second cycle of orthophoto or every 4 years.
To a lesser extent the planimetric data set would also require update for areas of
change. Depending on the City's GIS needs, this could be updated on request rather
than a full systematic update. Planimetric changes would already be evident in the
updated orthophoto imagery and the City may not require updated vector collection.
The estimated budget for an orthophoto update every 2 years would be approximately
$60,000. This would include minor DTM updates for orthophoto purposes only and
would not include the generation of new contours or updated planimetric features.
The estimated effort and subsequent budgets for systematic DTM and planimetric
update would depend on the amount of change in the 4 year cycle . Our past
experience is that a systematic update and upgrade of a DTM data or planimetric data
set would require approximately 25 -30% of the effort of the original collection.
This effort is due to the scattered nature of change and the fact that the entire data set
has to be inspected to ensure the specification for update are met. If an ongoing
process for monitoring change can be established whereby the City tracks all change
areas and supplies this information to the update contractor, this would eliminate the
need for a systematic photogrammetric upgrade thereby reducing the cost to the City.
