Orthorectification involves the raw digital raster images that were created by scanning the aerial negatives or capturing the digital imagery. Operations are performed on high performance Digital Photogrammetric Workstations running the KLT Associates photogrammetric software suite. The unrectified raster images are georeferenced to the digital terrain models (DTMs) using the GPS control, digital aerotriangulation and aerial camera data.

Delivery formats for the orthophoto mosaics include but are not limited to TIFF, GeoTiff, MrSID, JPEG, and ECW. World files are supplied as part of ortho tile/mosaic or embedded in the raster data file.
