Orthorectification involves the raw digital raster images that were created by capturing the imagery with a digital sensor. 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 digital sensor data.

Delivery formats for the orthoimagery 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.
