METHOD FOR REPRESENTING TERRAIN, METHOD FOR CREATING TERRAIN PRIMITIVES, AND APPARATUS USING THE METHODS

摘要

A method for representing a terrain, a method for creating terrain primitives, and an apparatus using the methods are disclosed. The terrain representation method includes: reading digital elevation model (DEM) data of a terrain; extracting feature points of the terrain from the DEM data of the terrain; creating a plurality of terrain primitives according to the feature points of the terrain; storing terrain representation model data based on the plurality of terrain primitives; and converting the terrain primitive based terrain representation model data into DEM data, and visualizing the DEM data.
