Remotely sensing images show the features on the earth surface which are geometricallydistorted due the main errors related to the satellite positioning on its orbit or scanning process. Inthis work, using Global Positioning System (GPS) for geometric correction of satellite imagery toestablish the relation between the image coordinate system and the GPS readout coordinate system.Measurements are presented for two satellite images high resolution Quick Bird and low resolutionLand sat. The two –dimensional accuracies are low for Land sat image such as x and y coordinateserror 0.9951 m, and 1.2036 respectively and total error is1.5617 m, While for Quick Bird image thetwo –dimensional accuracies are high where the errors are 0.3374 m and 0.2115 m respectively, andthe total error is 0.3982 m. In the present study shows the ability to give high accuracy ofgeoreferenced coordinate system of the Quick Bird image, while the Landsat image produces lowaccuracy.
