遥感影像在矿区地形图更新中的应用

he question is that renewal topographical map necessity and urgency for coal mine area. In the article, the remote sensing data source is SPOT-5 image of Chenzhuang Area of Huaibei in 2005. After the series of processing to the image, such as image enhancement, geometric correction, registration, merging, clipping, was regarded as base map, which is superimposed and interpreted with the 1:5000 topographic maps in 2003 after coordinate, projection transforming and vector stratifying. By updating the main ground object such as settlement place, road and water system, we get the 1:5000 topographic maps in 2005. The renewed result shows that the precision of the processed remote sensing images is able to meet the need of 1:5000 topographic maps updating.
