摘要
实现遥感信息机助制图是加速遥感应用的重要技术手段。以TM图像的初级分类图为依据,根据分类图像的特点,结合专题地图的制图原则,介绍了用分层滤波法进行图像的综合取舍,并与GIS相结合,实现快速自动成图的过程和方法。对于提高图像专题分析的技术水平,快速及时地提供资料,以及促进遥感与地理信息系统的结合进行了探索。
The realization of automatic mapping of remote sensed information is an important technical means which speed up the remote sensing application.The essay that depended on the character of TM classified image and the principles of thematic mapping has presended the porcedure as well as the method of computer aided cartographic on how to generalize image by means of the layer division filter and combine GIS.This is an instructive research which will improve the technical level of thematic analysis,provide quick and timely data and accelerate the combination of remote sensing with GIS.
