process against defined acceptance criteria. This process will verify the positional accuracy
of the data, and ensure its aesthetic and functional quality. The County will conduct this
quality control review via Sanborn’s GeoServe online platform and review of the final
products delivered on hard drive in accordance with the specifications set out in Acceptance
Criteria in Section 8.5.8. If County determines that the final products do not meet the

x Aerial Triangulation (AT)
x Sanborn QC and approval of AT results
x Digital Elevation Model (DEM) for oblique imagery
x Upon internal acceptance, Sanborn to publish imagery on Sanborn Oblique Analyst®
8.6.2. Oblique Imagery Accuracy and Production
The oblique imagery accuracy will be a horizontal RMSE of 2-pixel and a vertical accuracy of
3-pixels. AT for oblique imagery systems employs a similar technique to the conventional
AT; for example, both include the use of ABGPS/IMU data and ground control points.
However, conventional AT software was not designed to incorporate oblique imagery for tie
point generation or to handle the large amount of data collected with the system. There are
two approaches Sanborn considers to ensure the highest accuracy possible for the nadir and
oblique imagery:
x Perform AT with the nadir image only and, using the results, compute the orientation
of the oblique imagery thus assuring a singular orientation system; or,
x Perform point matching on all nadir and oblique frames and utilize additional
parameters; e.g., trajectory and timing information into a bundle block solution. This
approach allows the identification and removal of errors associated with the
individual cameras within the system and with the GPS trajectory. This method
allows for tight quality control through all steps in the process, maximizing the
resultant accuracy of all images in the block.
With both solutions, AGPS/IMU and ground control are key elements in assessing the final
accuracy of the imagery.
Following completion of the data acquisition flight, a suite of image processing, GPS and
inertial data processing, and quality control software is used to produce a set of five
georeferenced images at each exposure station. The image database will be color balanced,
and quality control inspections with be performed to ensure integrity of the data set.
The completed oblique and nadir images will be uploaded into the Sanborn Oblique
Analyst®.

8.6.3. Viewer Capabilities
The toolbar is available at the top left corner of the Oblique Analyst®. To view and
access all 5 imagery angles, select the ‘Set Location’ and click on an area in the
large imagery display. The view will center on the location where you clicked, and all
5 views will appear in the thumbnails. You can then select and zoom, pan, navigate
and more, in any of the views. Choose ‘Set Location’ and select a new area,
building or feature to continue to view multiple images as you navigate through the
imagery.
The angle which is inherent to oblique imagery allows viewers to see not only the top
of objects but the sides as well. All 5 views (1 nadir view and 4 views angled at 45
degrees from the nadir) are viewable in the Oblique Analyst®. The user can select a
view to be the primary view and then switch back and forth with other views. An
overview map is also available in the bottom right corner of the Oblique Analyst®.
The Oblique Analyst® has a large selection of tools and options to be used while
exploring the imagery. These features include:
x The ability to pan and zoom around in the project area to explore views of
the selected location. Users can zoom in and out with the zoom
buttons or use the scroll wheel on the mouse.
x A compass feature allowing users always know the direction of the
current view. The half circle button in the middle indicates the nadir or top-
down view. The triangle button in the center indicates a top-down, north-up
navigation view which is also used to view WMS/WFS layers.
x An overview map (bottom right corner) allowing users know the exact
location within the project area.

x An addressing feature to quickly locate a specific address,
incorporating the County’s geocoding services.

URL parameters, i.e., users/other applications can start the viewer at a specified
location by using one of the following URL parameters.
Coordinates: http://<Viewer site>/<Viewer name>/?ll=lat,long
Address: http://<Viewer site>/<Viewer name>/?addr=address

8.8.2. Post Disaster Imagery and Lidar Collection
If the County has contracted with Sanborn for multiple oblique flights, Sanborn will capture and
deliver 12-inch georeferenced imagery to the County for up to 200 square miles of affected areas
as determined by Sanborn for a qualifying natural disaster event as described below:
o Wildfire: Affected Areas of the County impacted by wildfires with a minimum of 50 square
miles of contiguous burn area.
o Earthquake: Affected Areas of the County impacted by an Earthquake of 6.0 or greater,
according to the Richter Magnitude Scale (ML).
o Terrorist/Man-Made: Affected Areas of the County damaging over 200 sq. miles of area
resulting from a terrorist attack or other man-made disaster.
o Hurricane: Affected Areas of the County impacted by Saffir-Simpson Scale Rating of
Category three (3) or higher
o Tornado: Affected Areas of the County impacted by Tornadoes with Enhanced Fujita (EF)
Rating of Four (4) and above.

imagery to the County.
Sanborn will deliver the 12-inch georeferenced imagery via web-based platform, Sanborn Image

miles or 2nd or more captures.
o For contiguous areas beyond the complimentary 200 sq. miles, the cost for 12-
inch georeferenced imagery would be $48.64 per sq. mile.
o The post-disaster complimentary service does not include lidar collection. For
contiguous areas at least 200 sq. miles or more for a qualifying natural disaster
