SPOT5卫星影像在1∶1万地形图修测中的应用

摘要

SPOT5 satellite remote sensingimages were procesed by image enhancement,image regis-tration,image fusion and image ortho rectification.Then the processed images were vectorquantized field mapped and indoor arranged,By comparison,the SPOT5 images and graphic maps were updated with less workload,low price,and easy operation.But some features in the image map were not easy to deter-mine.So the SPOT5 satellite image has certain application value in the 1∶1 milliontopographic map revision.%研究对 SPOT5卫星遥感影像进行影像增强、影像配准、影像融合和影像正射纠正一系列图像处理，对处理好的影像进行矢量化，通过在外业实地调绘及内业图形整理，进行比较。得出 SPOT5影像更新地形图价格低、工作量少且易于操作，因此，SPOT5卫星影像在1∶1万地形图修测中有一定的应用价值，但是有些地物在影像图上不易判别。
