| 摘 要： | 应用Google Earth中提取的DEM,SRTM,以及ASTER-GDEM 3种公开免费使用的DEM数据,将这3种数据进行格式转换、坐标转换等预处理后,在MapGIS中对某一给定范围及处理高程的区域进行了挖填方估算,对原始DEM和设计DEM均实现了可视化显示。本文为各种工程项目设计阶段的工程量快速概算提供了指导意义。

| Abstract: | After application of Google Earth extracted DEM , SRTM and ASTER-GDEM three DEM data publicly free to use , these three data format conversion , coordinate conversion pretreatment in MapGIS in a given range of elevation and handling square cut and fill areas were estimated for the original DEM and DEM are designed to achieve a visual display .In this paper , for a variety of engi-neering design phase of the project provides guidance quick estimates . |
