Correction of georeferencing and detection of errors in DEMs

A surface matching algorithm has been applied for the accurate registration of digital elevation models into the same coordinate system and thus for the correction of errors in the georeferencing of the DEMs. The difference images after surface matching reveal distortions in the DEMs which were difficult to detect from a single DEM or from two inaccurately georeferenced DEMs. The method has been tested with DEMs produced from various spaceborne, airborne, and terrestrial data. The potential use of the method is to improve current techniques for DEM production.
