Based on high-resolution TerraSAR-X (TSX) stereo pairs, an investigation was launched addressing the retrieval of 3D point information from such data sets. The objectives were to determine 3D accuracies on the one hand, and to conclude on the best suitable image acquisition scenarios on the other hand. Related investigations using TerraSAR-X Spotlight as well as Stripmap multi-image data sets have shown that attractive 3D point quality can be achieved from such data sets. Thus, this approach of 3D point extraction could be reasonably utilized to establish control point data bases, particularly in poorly mapped areas.
