利用ASTERGlobalDEM和GoogleEarth卫星遥感影像辅助电力工程选址选线

介绍了ASTER Global DEM数据和Google Earth影像特点,以及阐述通过定制与检查DEM数据、卫星影像下载与纠正、数据基准转换与投影变换、等高线生成与影像叠加四个环节来制作遥感影像地图的方法.结合工程实践经验,说明该方法适合于难以获取基础地理信息的区域,能辅助电力工程的选址选线.

Using ASTER Global DEM and Google Earth Images to Assist Electric Power Engineering Project Site and Route Selection

This paper described the features of ASTER Global DEM data and Google Earth Image,as well as the main four steps of the satellite image map production method,including DEM data customization and inspection,satellite image download and geometric correction,datum transformation and projection,contour generation and image overlay.Combined with practical experience on projects,it indicated that the method was suitable for the area from where it was hard to obtain the basic geography information,and it can be us...
