CONSTRUCTING A GLOBAL DIGITAL DATA BASE USING A WORLD HYPSOMETRIC MAP AT 1:15,000,000 SCALE: PRELIMINARY RESULTS

Abstract

The authors describe the results of an experiment in compiling a data base for a global digital terrain model from information contained on a 1:15,000,000-scale hypsometric map. Particular emphasis is placed on strategies for digitizing terrain data from the original map. A key feature affecting the results of such modeling is the delineation of continental boundaries—whether at the ocean shoreline or the edge of the continental shelf.
