Abstract: High resolution satellite images is still used in large scale mapping due to the need to produce fastproducts. High resolution stereoscopic satellite images present good enough 3d products that include thebenefits of large-scale coverage and low-cost products. A stereopair of IKONOS satellite is used in thisresearch that covers a part of North Sudan country. The study handles the 3d mapping accuracy of usingstereoscopic satellite images. The study gives a spotlight on the accuracy in X, Y, Z and the space vectorR. Another view of this study the N, E and elevation is indicated. The research environment is mainlyENVI software due to its capabilities of topographic processing module. Some distributed set of groundpoints (control and tie) was determined on the images and then observed using GPS surveying. Severalexperiments have been performed to evaluate the resulted mapping product.Keywords: Stereoscopic; High Resolution; Satellite Images; Spatial Accuracy.
