| Abstract: | Acquiring building height is a major issue in the construction of city 3D model.The paper puts forward a method of acquiring building heights using large scale city 3D DLG data,which is capable of acquiring building heights in batches and solves the problem of acquiring the height of building of different roof structure.Building heights acquired in this way is high in precision and can meet the requirement of precise modeling of buildings. |

| Keywords: | 3D DLG building height bulk calculate precise modeling |
