变压吸附技术的应用及其发展简述

首先阐述了制作三维地形模型的重要意义,然后对现有1∶500地形图的高程要素进行了分析,提出了利用1∶500地形图制作三维地形模型数据的生产方法。本文着重对如何利用1∶500地形图中的重要地形要素,借助VC＋＋6.0语言将1∶500地形图中的二维地形要素面转换为三维面,并将数据导入3ds Max中快速制作出三维地形模型。通过对三维地形模型高程精度的检测表明：本文利用1∶500地形图制作三维地形模型的方法是可行的。

The Application and Development of PSA Technology

first expounded make 3D terrain model of important significance,then to existing 1∶500 DLG key element analysis,put forward the creative use of 1∶500 topographic map making 3D terrain model data production methods.This paper focuses on how to use the important 1∶500 topographic map landform elements,with VC ++ 6.0 language will 1∶500 topographic map of 2D terrain factors for 3D face face conversion,and 3ds Max data import quickly produce 3D terrain model.Through 3D terrain model elevation to the accuracy of the test indicated: this paper,by using 1∶500 topographic map making 3D terrain model method is feasible.
