Abstract
The presence of the photogrammetry method with diverse features have solved complex problems in different areas of research, such as stereophoto taken from airplanes to draw the terrain contour. Although this method has advantages compared to the traditional methods, it has a limitation on geology research. Thereíbre, in this paper, the author introduces an experimental result using algorithm of photogrammetry method based on stereophoto for rebuilding an object surface as well as simulating it’s slope suríace, slope section in three space. These results were obtained by prcýects of analysing slope stability along high way in South Korea.
