Informative accuracy investigation and updating map using remote sensing technique and GIS
In this work, using GPS which has best accuracy that can be established set of GCPs, also two satellite images can be used, first with high resolution QuickBird, and second has low resolution Landsat image and topographic maps with 1:100,000 and 1:250,000 scales.The implementing of these factors (GPS, two satellite images, different scales for topo
