Abstract
This paper discusses the use of Landsat 5 multitemporal satellite imagery to analyze land cover changes in due to landslide in Paya Ateuk sub-district Aceh Selatan province in May 2008. Satellite images data used are 2007 and 2009. Change vector analysis (CVA) and image differencing method with component analysis greenness, brightness and wetness and components vegetation index NDVI, BI and NDWI is use in this journal. It is known that land cover changes due to landslides can be detected using image differencing method and the CVA method, CVA method can be used to stratify various types of land cover changes due to landslides. Using multispectral classification NDVI component, known that the open land area due to landslides is 1,170 m2, with landslide avalanche length is 1,823 m, at the slope of 25-40% to > 40%
