Abstract: Geography information systems (GIS) displays and deals with the geography data with images. And the importance of digital image processing in CMS become evident. This paper discusses the basie concept of GIS and digital image processing and the mathematical model of coordinate change in GIS. Especially,digital image compresses in GIS and digital image division in GIS and so on. This paper points out the future development and presents challenge of digital image processing in GIS.
