Title: Cass_NW.sid Geospatial_Data_Presentation_Form: remote-sensing image Other_Citation_Details: Sanborn Map Company, Inc. 1925 Jamboree Drive, Suite 100 Colorado Springs, Colorado 80920 Online_Linkage: \\CC-GIS\Data\CassData\Images\Color1ft\MrSid\Cass_NW.sid Description: Abstract: This dataset consists of a color MrSid digital ortho image of North Western Cass County. The file was generated by compressing mosaicked 24-bit color TIFF files (based on the section tile grid) Purpose: Developed for use as part of a seamless mosaic for Cass County, ND. Supplemental_Information: The images were flown within a time period of April 22-28th, 2004 by Sanborn Map Company, Inc. of Colorado Springs, Colorado. The photo scale is 1" = 1500, the map scale is 1"= 200ft. The original format was color TIFFs based on the section grid.

The ground control data was supplemented with APGS data and any existing control that was collected during the photographic mission. The APGS was post-processed to provide high accuracy positions of the aerial camera at each instant of exposure. All control data was input as observations during the aerial triangulation solution. A new DEM was collected using softcopy workstations from the 1"=1500"scale scanned photography. The resulting DEM was used to support the production of the Orthophoto imagery. The Orthophotos were produced by scanning the aerial film negatives, incorporating the exterior orientation of the AT solution, and rectifying it to the DEM.
