The Study on Building of Virtual Reality System in Large Surface Coal Mine

International audienceThe building of virtual reality system for the opencast mine is a complicated and systemic project. The building process of virtual system includes data collection, GIS geodabase, model designing and raster textures making. GIS data is from field survey, maps, and remote sensing images. The import phase is the building of kinds of models in different environment. This paper introduced several methods for the modeling different entity, such as dumps, pits, building in Industrial sites, and reclaimed vegetation. The dump models includes real and designed entity in GIS. The building models are built by GIS data and 3DMAX.The vegetation models is builtup in other special software. Based on the ArcGlobe, the kinds of models are integrated into the virtual reality system. ArcGlobe allows efficient display and query of raster data and GIS data, and it is integrated to function with the ArcGIS geodatabase while providing support for analysis in the geoprocessing environment
