Analysis of Geolocation Accuracy of KOMPSAT-3 Imagery

open access: yesKorean Journal of Remote Sensing, 2014
This paper reports the geolocation accuracy of KOMPSAT-3 imagery. KOMPSAT-3 was launched successfully on May 18, 2012 and has been released last March. In this paper, we have checked the geolocation accuracy of initial sensor model, precise sensor model and stereo-and multi-image model using four KOMPSAT-3 images covering the same area.
