摘要：Nowadays because of high potential of satellite images, maps production procedure and their updating increasingly go towards using satellite photogrammetry. With regard to Iran's restrictions to access to suitable satellite images for production and revision of medium and large scale topographic maps, installation of IRS-P5 receiver in country provides a suitable opportunity for 1:25000 scale maps production and acceleration of their revision procedure. As far as, one of the basic problems using satellite images in maps production and their revision is their lower information content as compared with aerial images, in addition to evaluation of geometric accuracy of these images, in this paper we evaluate the information content of the IRS-P5 stereo images for production and revision of 1:25000 scale maps. The result of these evaluations show that the IRS-P5 stereo images, from the point of geometric accuracy, have the capability of 1:25000 scale maps revision, also, from the point of information content, have the capability of revision for some objects such as building blocks, roads, and vegetation cover. Revision of other objects in 1:25000 scale maps that are problematic in their identifying and extracting is completing using other mapping methods
