Summary:Presents a method for automatic digital elevation model (DEM) extraction using Korea Multi-Purpose Satellite (KOMPSAT) stereo images with the ground sample distance of 6.6 m and the swath width of 17 km by push broom scanning. After a matching procedure including estimation of the orientation and position of KOMPSAT, we calculate heights by using disparity information taken in the previous step. Experiments on 2592 by 2796 panchromatic KOMPSAT full scenes with 25 ground control points show that the planimetric and altimetric RMS errors are both below 1.5 pixels.
