| Abstract: | This paper presents the principle of topographic map compilation and relevant coordinate transformation with remote sensing and computer. Coordinate of image is obtained from aerial photograph , corrected with computer, changed into coordinate of surfece features , then into CAD data.Topographic map is output. The advantage of this system is high - speed, high - precision, low cost. |
