A Plan for Comparing the Triangulated Irregular Networks (TIN) and Uniform Rectangular Grid (URG) Methods of Digital Terrain Modeling.

摘要

Digital terrain modeling (DTM) is concerned with the digital storage, analysis, and display of surface configuration data (x,y,z) for topographic mapping. The field of DTM is relatively new and growing. Many methods of DTM have been studied and applied to real problems, but two are of concern here: the uniform rectangular grid (URG) and the triangulated irregular network (TIN) methods. This technical note presents preliminary evaluation methodology that will be used to compare the TIN and URG methods in the specific context of Marine Corps ground combat operations.
