EarthData International collected ADS-40/ISTAR-derived orthophotography over Hillsborough, Pinellas, Manatee and Sarasota Counties Florida with a 1 foot pixel resolution. The period of collection was between 9 January and 20 January 2007 for the base area with the agricultural area bring flown between 17 February and 19 February 2007. The collection was performed EarthData Aviation, using a Leica ADS-40 camera system, including an inertial measuring unit (IMU) and a dual frequency GPS receiver. This project required eight lifts of flight lines to be collected, for a total of 80 flight lines. The orthophotos were rectified using the existing lidar DEM from Pinellas County and a collected DEM from Hillsborough County and was processed using ISTAR. Ground survey services in support of the project were provided by a Florida-registered professional land surveyor under the employment of Terrasurv Inc. of PA. The GeoTIFF format was compressed to MrSid format for distribution or is stored in ArcSDE for District use.
