A Study on the GCP Disposition of KOMPSAT-1

There are invisible wars going on to preoccupy required satellite information for national defense, industry and living in the out space. Therefore, Korea has developed and successfully launched KOMPSAT (Korea Multi-Purpose SATellite), Korea's first multi-pur pose applications satellite, on December 21, 1999. In the course of geometric corrections with KOMPSAT-1 images, an accuracy of GCP collections is analyzed by the coordinated of digital map respective and an accuracy according to the GCP disposition was analyzed as well. For disposition of GCP, it turned out that even distribution on the whole screen contributes to promote accuracy. These are expected to used as basic data in putting the KOMPSAT-1 geometric correction into practical use.
