Like other developed countries, Taiwan is facing dynamic changes in land use due to rapid economic growth and frequent natural disasters such as earthquakes and typhoons. In the aftermath of a disaster, there is an urgent need for timely remote-sensing data to monitor and assess damage. Thus, in 1991, the National Space Organization (NSPO) was founded by the National Science Council (NSC) as a governmental agency to execute the national space program (NSPO 2005). Currently, two satellites are operated by NSPO to collect remote-sensing data. The first NSPO satellite, FORMOSAT-1, was successfully launched in 1999 to carry out three scientific research missions, including ocean colour imaging, experiments on ionospheric plasma and electrodynamics, and Ka-band (20–30 GHz) communications experiments. The second satellite, FORMOSAT-2, takes land images to meet Taiwanese civilian needs by providing black and white images with a resolution of 2 m and colour images of 8-m resolution (table 1). Also, an imager on board FORMOSAT-2 observes upper atmospheric lightning (the first time from a satellite).

N2 - The Sumatra earthquake struck South Asia on 26 December 2004 and triggered monstrous waves that turned into a tsunami hitting the ocean regions and caused the most severe natural disaster of recent decades. The devastating earthquake and tsunami changed the landscape of coastal areas in many countries around the whole Indian Ocean region. To provide real-time information for rescue and rehabilitation plans, satellite images were applied to monitor and evaluate the damage over several devastated spots. The FORMOSAT-2 satellite, which was launched on 21 May 2004 and operated by the National Space Organization, Taiwan, is uniquely designed to take timely and low-cost black and white images daily with a resolution of 2 m and colour images of 8-m resolution. FORMOSAT-2 is expected to have many useful applications, such as natural-disaster evaluation, land-usage analysis, environmental monitoring, and coastal search and rescue. FORMOSAT-2 successfully acquired several post-tsunami images of the hazardous areas, both Puhket, Thailand and Banda Aceh, Indonesia on 28 December. A series of FORMOSAT-2 satellite images were processed by geometric and radiometric correction, haze reduction, image enhancement, feature extraction, image classification, and image fusion to assess the damage over those devastated areas. FORMOSAT-2 satellite images with a high-temporal resolution and high-spatial resolution were proved to be an efficient and useful information source for decision-makers to make rescue and recovery plans, especially for some isolated islands hard to reach in time.
