Abstract
An algorithm to enhance and complete digital hypsography data was developed at the Center for Mapping, The Ohio State University. The method is defined in terms of topographic and cartographic treatment processing modules. The "thematic rules' in these modules aim to reconstruct the terrain and comply with the cartographic treatments and standards that were used in compiling the original source mapping data. The topography processing module was based on reconstruction of contour lines between pairs of breaklines. The unique approach in this module was to detect unexplained discontinuities of the terrain represented by the digitized contours. The algorithm was tested successfully on U.S.G.S. 1:24 000-scale 7.5′ quadrangles. The newly developed software seems to be a promising basis for a fast, automated process to enhance and complete these large digital hypsography data files. -from Author
