Sand covered area in Parangtritis sand dunes has decreased significantly due to massive land-use changes. This research aims to map this sand covered area changes using NDVI, NDSI, and clay index. We use Landsat MSS, TM, ETM+, and OLI & TIRS sensors on red, NIR, and SWIR 1 & 2 bands. The NDVI, NDSI, and clay index are presented in a composite to distinguish sand and non-sand objects, then are classified using supervised technique with ROI from the sand and non-sand land cover. With the annual degradation above 7.71 hectares, it will be all covered by other land uses in eight years.
