| Abstract | Precise ground coordinates in the restitution from raster data is a key point for their integration in geographic information systems. This paper presents methods and results of the restitution of
planimetric and altimetric features from digital stereo data (SPOT-PLA and airborne SAR) in stereoscopic mode. The method uses a photogrammetric approach. The stereo restitution is done with a digital video plotter using low-cost hardware (PC), and
comparisons of the results with the digital topographic map are done in the ARC/INFO environment. Results from spot stereo pair in the Rocky Mountains (Canada) show a planimetric accuracy of 12 m with 90% confidence for well-identifiable features,
and an altimetric accuracy for a DEM of 30 m with 90% confidence. First results from a stereo SAR pair show residuals of 5 m in planimetry and 20 m in altimetry when the stereo model is formed. The restitution has not been completely finished and
evaluated. |
