Abstract :
This study reports on the surface reconstruction from high resolution satellite imagery with the terrain-dependent RFM (rational function model). The study area covers 17 km×14 km with two pairs of stereo images. The overlapped area is taken from SPOT panchromatic and KOMPSAT (Korea Multi-Purpose Satellite) stereo images. The ground resolution of each image is 10 m and 6.6 m, respectively. We improved the accuracy of RFM using correlation analysis for both images. We then successfully created surface DEM (digital elevation model) for the overlapped areas of both images.
