Data Source


Title: 2015 City of Philadelphia AccuPlus Orthomosaic
This dataset consists of ortho imagery produced from nadir images captured by Pictometry International covering the City of Philadelphia, PA, approximately 196 sq miles total. Automatic aerial triangulation (AAT) was performed. The triangulated frames were rectified to a LiDAR derived DEM. Mosaicing was performed using an automatic seaming algorithm and manually edited to eliminate seams through elevated features where possible. The dataset includes 1024 GeoTIFF files, 1 ECW, and 1 MrSID file. The data was collected at a 3in Ground Sample Distance (GSD) over between April 12 and May 8th, 2015. At the time of capture ground condiitons were leaf-off, snow free, and water was at normal levels.

GPS/INS Processing: During the flight, GPS and INS data was logged on board the aircraft. Simultaneously, GPS data was logged by a stationary reference station network on the ground. After completion of the flight, this data was post-processed using Applanix POSPac v7.1 to generate a smoothed best estimate trajectory (SBET).
