| 摘 要： | 数字三维是当今研究的热点,三维建模高程是基础。然而,我国大中比例尺地形图获取困难,且扫描并矢量化费时费力,建模相对复杂。Google Earth不仅提供了高分辨率的影像,还提供了另一项重要数据:海拔高程。本文研究了在VS平台下,提取Google Earth高程数据,利用GIS软件制作高程图的方法,并对制作的高程图进行了对比分析。

| Abstract: | Digital 3D is currently a hot research,and elevation is the foundation of three-dimensional modeling.However,it is difficult to get China’s large and medium scale topographic maps,and the map scanning and vectorization are a waste of time and money,modeling relatively complex.Google Earth not only provides high-resolution images,but also provides another important data：altitude.In this paper,methods of making elevation maps by using GIS software and extracting Google Earth elevation data on the VS platform are introduced,and the elevation maps are analyzed comparatively. |
