摘要
分析了SPOT和TM卫星影像的特点,提出综合利用SPOT和TM卫星影像的方法。对这两种影像进行融合,提取融合后的影像数据,使之与GIS数据库相叠加,达到时GIS矢量数据库更新的目的。以土地利用数据库为例进行实践,取得了较好的效果。
This paper first analyzes the characteristics of SPOT and TM satellites, and brings forward the method of using SPOT and TM satellites images synthetically. First fuses these two kinds of images, then distills the image data from these images and splices them with GIS database aiming to updates the GIS vector database. At the end a practice on land database which gained good effects.
