摘要：Geographical information such as elevations or immission, is most often represented either as vectors, e.g. isolines,or as raster, e.g. density slicing. Here, the precision of the representation is dealt with. Special attention is paid tothe accuracy of secondary forms of information such as terrain slopes as derived from OEMs. For a mathematicalanalysis, synthetic surfaces are employed. As a conclusion, new ways are shown to visualize the quality ofgeographical data
