| Abstract | ||
| Remotely sensing images show the features on the earth surface which are geometrically distorted due the main errors related to the satellite positioning on its orbit or scanning process. In this work, using Global Positioning System (GPS) for geometric correction of satellite imagery to establish 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 resolution Land sat. The two –dimensional accuracies are low for Land sat image such as x and y coordinates error 0.9951 m, and 1.2036 respectively and total error is1.5617 m, While for Quick Bird image the two –dimensional accuracies are high where the errors are 0.3374 m and 0.2115 m respectively, and the total error is 0.3982 m. In the present study shows the ability to give high accuracy of georeferenced coordinate system of the Quick Bird image, while the Landsat image produces low accuracy. | ||
