摘要
以勉宁高速公路为例,在1:2000的公路沿线地形平面图的基础上,利用AutoCAD和R2V软件对其进行预处理,然后在ArcGIS中建立高精度的DEM,通过DEM和公路沿线平面图的叠加,生成公路沿线单个三维地形,建立Oracle数据库存储二维和三维地形数据,并对其中三维数据进行了缓冲区、面积和体积计算等三维应用分析。
The essay via AutoCAD and R2V software for pre - processing based on 1 : 2000 ground plot on the Mian Xian-Ning Shan Express Way, establishing higher precision DEM in ArcGIS via superimposing plot to form three dimensional terrain to construct Oracle data bank restoring two and three dimensional terrain data and made applicable analysis on buffer regions, area and volume computation via three dimension data.
