The construction of 3D model is the core of three -dimensional urban geographic information system. In this paper, the process flow of three - dimensional modeling based on existing data is introduced, and the new method of acquiring building height based on large -scale 3D DLG is studied. According to the process flow above, large -area construction of 3D urban model is solved properly, and the 3D model has high precision to satisfy the precision requirements of 3D model totally.
