Abstract

In 1993 an airborne Gps-assisted photogrammetry project was carried out in the Victoria Land region (Antarctica) with the performance of 12 aerial photography missions. Successful application of Gps photogrammetry allows for reduction of the number of ground control points (Gcp). The benefits of airborne Gps in the production of high-accuracy spatially referenced data deserves particular attention when operating in difficult environments, such as polar regions for glacier monitoring or mapping purposes. Gps determined positions of photo centers and control points can be used during the aerotriangulation procedure preliminary to the photogrammetric plotting. A comparison between the digital and analytical aerotriangulation approach is made in the paper. Furthermore an images auto-correlation algorithm was tried out for the automatic production of the ice shelf Digital Terrain Model (Dtm) and relative ortophoto production.
