摘要：This paper presents a methodology for planimetric adjustment of elevation data to the SRTM Digital Elevation Model (SRTM- DEM), by correlation. It can be applied to geo-reference any geographic dataset with an elevation component, such as rasterised maps with contours or DEMs. The accuracy around 5 meters was achieved by this geo-referencing method assessed using elevation data from Portugal derived by photogrammetric techniques. The method was then used to geo-reference old topographic maps of former Portuguese colonies, which were in local geodetic datums not well related to WGS-84. The consistency of planimetric datum shifts determined was consistent with the scales of the maps analysed. The method allowed for the use of these old maps without any extra field work
