This paper presents a fully digital photogrammetric method for the restitution of various types of stereo imagery (visible and SAR; spaceborne and airborne) using the same digital stereo workstation, the DVP. Based on personal computer, the DVP system enables the on-line three dimensional reconstruction of a stereo-model, the capture in real time of data from the raw images and the graphic overlay of vector data. The mathematical equations, which drive the DVP, are based on the collinearity and co-planarity conditions and integrate the platform, sensor, Earth and cartographic projection models into a single model. Data is extracted using the DVP system and compared to digital topographic data. Three different challenging study sites and data sets have been selected to test the limits of the method and the DVP system. Planimetric accuracies of 6.5 m, 30.0 m and 17.0 m, and altimetric accuracies of 12.6 m, 38.0 m and 23.9 m have been achieved with SPOT-P, airborne SAR and ERS-SAR stereo-pairs, respectively. Better results should be achievable with less challenging study sites and data sets.
