Mapping mangrove degradation in Pahang river estuary, Pekan Pahang by using remote sensing

This study examined the mangrove degradation in Pahang River Estuary, Pekan sub-district, Pahang between 1990 and 2017 using supervised classification. Landsat 8 OLI and Landsat 5 TM images of Pahang River Estuary have been analyzed using supervised classification and field survey. Based on the accu...
