EarthData International collected ADS-40/ISTAR-derived orthophotos at a 50 centimeter pixel resolution to produce natural color and color infrared ortho photo tiles. The period of aerial collection was 14 DEC 2004 to 15 DEC 2004 with a reflight of several lines conducted on 1 FEB 2006. During the time of image acquisition two dual frequency GPS receivers were utilized. One receiver was operated on board the aircraft with the dual frequency antenna located directly over the camera. The second receiver was used as a base station.These receivers were in constant operation during the imagery mission and GPS phase data was collected at an epoch rate of 1 second. The airborne GPS data and IMU were used in combination with ground surveyed points to control the imagery. The imagery fully encompasses the project boundary. The DTM deliverable for this project was manually compiled using stereo pairs generated from the orthophoto flight. The DEM masspoint grid used to rectify the orthophotography was derived from the compiled DTM. All data produced for this project was referenced horizontally to NAD83, and vertically to Mean Sea Level(MSL), NAVD 88 in UTM meters.
