Overview of KOMPSAT-1 data applications

Since the successful launch of KOrea Multi-Purpose SATellite-1 (KOMPSAT-1) on Dec. 21, 1999, the optical sensors of Electro-Optical Camera (EOC) and Ocean Scanning Multi-spectral Imager (OSMI) aboard KOMPSAT-1 have been observing the global land and ocean, respectively. KARI distributed the KOMPSAT-1 data to government agencies, government-supported research institutes and universities for public use. And Korea Aerospace Industries (KAI) undertook the data dissemination for commercial use. To promote the development of remote sensing technology using the KOMPSAT-1 data, KARI has been collaborating with three research groups, each representing land applications, marine applications, and meteorological applications. The studies of land application group demonstrated that the EOC data are useful in the area of mapping, surveillance, land cover mapping, land use analysis, and disaster monitoring. Although much effort has been made in the calibration and validation of OSMI data, they have been successfully used to monitor yellow dust, forest fire, red tide, and typhoon. The current sensor calibration efforts in collaboration with NASA are expected to bring more outcomes related to the ocean color research. The presentation will summarize the status of KOMPSAT-1 data applications and highlight some results obtained from the above research groups.
