    • Abstract
  • A Virtual Geographical Environment is the expression and simulation of a geographical environment.It not only includes the simulation of the terrain surface information,but includes natural phenomena geospatial and processing simulation.3D terrain visualization is an indispensable part of Virtual Geographic Environment.Due to the nature of two-dimensional features it is difficult,to realistically simulate real three-dimensional volumes based on the traditional "Face model" typically used to build a virtual geographic environment.In this paper,we fully explore the basic concepts of voxels and features,based on the analysis of several common voxel models.We focus on the voxels in a virtual three-dimensional topography of the geographical environment for the simulation of natural phenomena,geographical expression of the process,spatial analysis based on geographic environment and applications.The virtual geographic environment based on "volume model" is dicusssed.
