The present work has been undertaken to prepare the multi-date vegetation density maps in terms of Normalised vegetation index (NDVI) and to monitor the changes in and around the areas close to transition, buffer and core boundaries of Similipal Biosphere Reserve (SBR) using digital remote sensing and GIS techniques.Time series Landsat images covering a period of 30 years are used for change detection studies.
