DATABASE CONSTRUCTION AND INTEGRATED DISPLAY OF 3D CITY MODELING DATA

Abstract. With the rapid development of computer technology and geographic information system (GIS), three-dimensional (3D) data are becoming an important aspect GIS. It can provide more than traditional two-dimensional (2D) surveying mapping data. plays vital role in city building management. In this paper, 3D modeling different type collected, including til t dataata, model data, BIM underground Then database construction is completed by using distributed method, which greatly improve efficiency access display. Furthermore, these processed published as standard services. a developed to display integrated with digital elevation (DEM) remote sensing image support for management various natural resources. future, there will be further optimization system. We continue promote application serve government people. also hope into
