Abstract
Digital height models (DHM's) from contour lines have particular significance due to the wide availability of contour sheets for topographic maps. The automatic conversion of contour lines to a rectangular raster of height values presents specific problems since artificial morphological structures are generated in the process of interpolation. Using 15 test terrain forms, we present and evaluate an algorithm designed to minimize this problem and we find overall interpolation results to compare well with manual interpolation, with differences amounting to 5 - 10% of the contourline interval. -ITC Bibliography
