x Acquisition QC and reflight calling
x Camera Calibration
x GPS-IMU Processing
x Image Processing and Color Finalization
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®
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 techniques 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.

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.
Use of Sanborn's Online Change Viewer, which allows for optimal side-by-side
comparison of Pre and Post-Disaster Imagery, is included in the delivery of
Sanborn’s Post-Disaster Imagery Services for a period of one hundred (100)
days from the date of delivery of any post-disaster imagery to the County.
Sanborn will deliver the 12-inch georeferenced imagery via web-based
platform, Sanborn Image QC™ and GeoTiff files.
The post-disaster imagery capture is complimentary up to 200 sq. miles and up
to 1 event per year. Please see the fee schedule for imagery capture that
exceed the 200 sq. miles or 2nd or more captures as below
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 as stated above, the cost for additional lidar
would be $139.89 per square mile for 2ppm and $277.62 per square
mile for 8ppm lidar data.
