This project is based on the Multi-Stage Remote Sensing GIS System established for Soil and Water Conservation Bureau in 2000, and increased Formosat-2 imagery of severe landslide areas from 2005 to 2010. To apply satellite imagery prior and after natural disasters in disaster interpretations, emergency responses have been processed in accordance with the debris flow warning published by SWCB in this year. With information collected during each emergency response, the rapid report of Formosat-2 imagery interpretation and the analysis list of Formasat-2 imagery interpretation on debris flow torrents were developed. Meanwhile, this project also assessed the practicability of using UAV for collecting GIS data after disasters, and completed the mission of taking aerial photos and variation analysis of 4 spots. Apart from these works, more data has been added to the Multi-Stage Remote Sensing GIS System while more user-friendly functions have been updated such as measurement of disaster area, four-window switch and potential landslide areas choosing list. Moreover, satellite imagery and related information of 5 international landslide disaster events were gathered as future disaster prevention reference. Eventually, this project held 2 training courses on Multi-Stage Remote Sensing GIS System and prepared course posters, lecture notes and audio files.
