摘要：Nowadays, due to improvements in satellite technology, remote sensing data is used for mapping at different scales. In Iran, there is a necessity to utilize satellite imagery as a complementary data source to aerial photographs. One of the main reasons for this, aside from the usual advantages of this technology, is the ability to map and revise border areas having aerial access limitations due to security reasons. This is especially true for Iran's 1:25000 scale base maps. In this paper the revision process of 1:25000 scale topographic maps will be discussed and explained. Generally, the satellite images can be applied either in the change detection phase or in applying the changes to the maps. In this research, SPOT 5 HRG images have been used for revision of 1:25000 scale base maps. Successful exploitation of the accuracy potential of SPOT 5 HRG depends on well defined and distributed GCPs and using of precise orthorectification process. Therefore Toutin's spot model has been used to orthorectify SPOT 5 HRG image. Based on obtained results, SPOT 5 HRG images, while having required planimetric accuracy at scale of 1:25000 (about 7.5m), provides the required information contents for such maps
