Abstract
3D modeling of urban building is becoming more and more popular. In this paper, Large-scale GIS data are used, which include digital line graphs (DLG), digital elevation model (DEM) and digital orthophoto map (DOM) to reconstruct urban buildings. Based on DLG, the building models are created, and then placed on a relief analog which is generated in the light of DEM. Building´s textures obtained from fieldwork is pasted to every side of those buildings. Our purpose is to bring forth a scene that is more close to the real world and vividly visualize building´s landscape.
