Triangulation spatiale de bloc d'images SPOT

Abstract : Besides its image quality, the main advantage of Sport system is its geometric accuracy. The aim of this study is the evaluation of what block adjustment can bring to Spot images geometric processing, in order to process together all the images of a space mapping project. The actual advantage of this kind of computation is shown here. Before, a model of the image-ground relationship must be given. The proposed model is simple, robust and close to the physical image acquisition. With very few control points, the resulting accuracy is less than 10 meters in planimetry, and 6 meters in altimetry. These figures fit most standards of 1:50000 scale topographic maps. Without any ground control point, the accuracy is 15 meters on 200 km x 200 km area.
