Abstract
The worst landslide causing massive destruction occurred in 1988 after being triggered by heavy rainstorms and many more have occurred since. Many researchers have focused their attention to the issue and urgently tried to find ways to prevent the lost of lives and properties if such phenomenon repeats itself. The objective of this study was to monitor the recovery of landslide areas after 20 years (1988-2008). The eight time-series data of LANDSAT imagery dated 1990, 1993, 1994, 1996, 1999, 2002, 2006, and 2007 were used. The Geographic Information System (GIS) and remote sensing (RS) technology were selected as the analytical tools. The changes of the NDVI and Greenness between the satellite images, representing the change of vegetation or land cover, were analyzed. Visual interpretation showed the improvement of the landslide areas. In addition, the quantitative analysis of land cover was calculated. © 2010 Copernicus GmbH. All rights reserved.
