In this research, fusion of SAR image (high resolution image -0.2 m) with Landsat image (low resolution image-30.0m) is done to enhance resolution of multispectral image for better identification of High Aswan Dam region that specific important part from Egypt. Preprocessing of both SAR and Landsat images is critical to get the best Enhancement. For SAR image, the information utilized for terra-SAR-x, getting backscatter image is our issue. Calibration done first then de-speckling to evacuate dot happened in accumulation SAR information, this system done by different methods of filtering, after that an appraisal done to get the best image from all strategies done, then utilize the image for doing combination with Landsat image in the wake of doing subset for our region of hobby. The outcomes demonstrated that utilizing mean with (7*7) portions issuing us great results instead of different systems. Fusion of Landsat image by SAR data was done using principal component method. A geologic interpretation is applied to the processed image.
