摘要
基于VirtuoZo NT3.6采用批量建模,根据已有地图制作特征文件,在立体模式下进行人机交互式作业制作DEM,再生成DOM。有效利用已有资料,减少了建模的繁琐操作,提高工作效率;特征文件的引入与立体模式下人机交互作业,从而提高精度。
This paper is mainly about the way to make DEM based on VirtuoZo NT3.6 with batch modeling,in accordance with established signature file of map production in the three-dimensional model of human-computer interactive operation carried out under the production of DEM,and then to generate the DOM;effective use of existing data to reduce the tedious modeling operations and improve work efficiency;use of the signature file into human-computer interaction and three-dimensional mode operation,thereby increasing precision.
