The program can automatically calculate the grid nodes’ ground elevations to a certain extension that could be applied to change ground-lines for finite element model.
NET开发环境,利用AutoCAD ActiveX技术,对AutoCAD2008进行二次开发,开发出快速建立初始地应力场反演计算三维有限元模型的面向对象程序,通过该程序可以根据需要自动读取一定范围内的网格节点地面高程,能够为有限元模型变地面线处理直接利用,避免了常规人工读取CAD地面高程的繁琐性和误差较大的问题,极大地提高了工作效率和准确性,快速便捷。
The Vegetation Classification Using FVC and DEM in South Xinjiang of China;
首先按数字地面高程将整个研究区分为三个子研究区:(1)低海拔平原荒漠、丘陵区,海拔高度≤2000m,主要植被为绿洲、平原荒漠类植被;(2)亚高山、中低山地地区,海拔高度在2000～3900m,主要植被为森林、亚高山草原、山地草原、山地荒漠草原、山地荒漠;(3)高山区,海拔高度>3900m,主要植被高山垫状植被、高寒荒漠。
The internal work of calculation after measurement of elevation at terrestrial characteristic points in municipal engineering works is usually done by the computer, with the results marked on CAD drawings, which is of low efficiency and high rate of errors.
市政工程中地面特征点高程测量后的内业工作都用计算器计算,再标注到CAD电子图上,效率低,易出差错。

For cartographical purposes heights are necessarily recorded above the geoid (sea-level).
就制图的目的来说，所以需记录的高程是高出大地水准面（海平面）的高程。
Elevation differences small compared with the earth's redius, this is proportional to the height above sea level.
高程差与地球半径相比显得很小，它与海洋面以上的高度成正比。
