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