Summary:This paper presents a framework for building bottom boundary rectification based on DEM data for removing the gap between the building model reconstructed by interactive modeling and the terrain surface data. First, the regular grid DEM data is converted into mesh data. Then, the positional relationship between building triangle faces and DEM mesh data is calculated through Z-coordinate and intersection analysis. The new textured triangle faces of the building model are created by the intersection points and building bottom boundary vertices. The experiment result shows that there is no gaps between the rectified building models and the terrain data and proves the effectiveness of the proposed framework.
