A Precision Geo-referenced Digital Airborne Camera System

A Precision Geo-referenced Digital Airborne Camera System (PG-DACS) is fully integrated with the latest 16-bit 4times5 cm format CCD camera, a precision GPS/IMU setup, a customized high performance industrial PC, and a dedicated PG- DACS operation autonomous software package. PG-DACS is a self-sustained portable airborne imaging system that can be quickly deployed aboard various fixed and rotary wing aerial vehicles. PG-DACS is developed for today's fast change detection needs with the leading performance in providing high spatial and temporal resolution, photogrammetric-grade aerial image products. Direct-georeference-capable, sub-inch resolution spotting airphotos, and two to six inch resolution continuous aerial stereo pairs for radiometrically corrected mapping-grade orthomosaics that cover long corridor and various sized cities and counties are parts of PG-DACS products.
