三维数字地形图测绘技术研究

三维数字地形图是将传统的平面二维数字地形图,增加一个高程的维度,使得平面的地理信息,以三维的空间坐标的形式展现,极大地丰富了地形图所展现的地理信息内容,让人们能够更加直观地去理解地形地貌,对智慧城市、工程设计等发展具有积极的推动作用.

Research on mapping technology of 3D digital topographic map

3D digital topographic map is to add a dimension of elevation to the traditional two-dimensional digital topographic map,so that the geographic information of the plane can be presented in the form of three-dimensional spatial coordinates.It greatly enriches the geographic information content displayed by the topographic map and enables people to understand the terrain and landform more intuitively.It will play a positive role in promoting the development of smart city and engineering design.
