dc.descriptionAbstract: The U.S. Anny Engineer Topographic Laboratories and the National Bureau of Standards investigated the computational feasibility of developing a contour-to-grid algorithm by: (l) sampling a large set of digitized cartographic contour data with a tolerance band technique, (2) its subsequent triangulation with a Voronoi (Delaunay, Thiessen) method and (3) the construction of an interpolating smooth synthetic surface from which grids can be generated at any given interval. This report presents a discussion on the results obtained.-
