| Abstract: | It is very important to establish the three-dimensional spatial information based on the Virtual Reality System,which could display dynamic interactive environments,analyze and deal with a variety of geographic data.In this paper,taking Qinghe forestry bureau as an example,the data of study region DEM and RS was collected,on this base and with the mosaic of DEM,the image of study was geometric corrected and enhanced.At last,the Three-dimensional Virtual Reality System of Qinghe forestry bureau was built. |
