摘要
以抚顺市为例,提取该市地形图中的高程点和等高线信息构建DEM,与相应区域的SPOT 5融合影像和森林资源调查小班数据进行叠加,制作三维影像,并实现简单的查询、定位、统计等功能.
Taking Fushun City as an example, the paper extracts the elevation and contour line of the city＇s topographic diagram to construct DEM, and overlaps SPOT 5 images with forest resource inventory data which includes the region to realize 3-Dimensional images. As a result, it achieves multi-functions such as available inquiring, orientation and statistics and so on.
