Abstract
High resolution satellite images (HRSI) such as QuickBird supply a lot of opportunities in mapping, GIS and many other applications. HRSI have to be geometrically and precisely processed with GCPs to get the accuracy needed for map updating. In this study, North-West part of LIBYA (in Tripoli Region) test field which has a flat topography is chosen as a test area. The test study area was covered with Orthorectified QuickBird image 60cm spatial resolution, large scale topography map produced from stereo aerial photo have been used as a reference data, ground control points (GCPs) and check points (CPs) was extracted. Geometric correction of the image will be done based on mathematic model (2D-polynomial) approach. From the results it can be say that the high resolution satellite images like QuickBird images are good source for updating large scale maps (1:5000).
