ENVIRONMENTAL CHANGE ANALYSIS IN NIAS ISLAND USING REMOTE SENSING TECHNIQUE

This research was aimed at identifying the environmetal change by using Landsat 5 TM satellite imagery and Landsat 8 OLI with NDVI and LST parameters in Nias island. It was conducted by using overlay method by utilizing the ArcGIS 10.0 software and ENVI 4.7, at the administrative boundary map in the local area which is supported by 40 control points (GCP) of direct observation in the research area. The results showed a decrease in the normalized difference vegetation index (NDVI) and the increase in the average of land surface temperature (LST), so that it can be concluded that there was environmental changes in Nias Island.
