Change Detection of Vegetation Cover by NDVI Technique on Catchment Area of the Panchet Hill Dam, India

2016 International Journal of Research in Geography  
Exhaustion of green cover has been started from the very beginning of the human civilization over space. Declining trend of natural forest owing to development projects emerges as problematic issue on environment. Dam construction by impeding of natural flow of river is a fact of depletion of green plants. It affects the vegetation on both upper and lower catchment area. This disturbance can be analyzed by different methods of Vegetation Index (VI) on the basis of Remote Sensing (RS) and

It is a numerical indicator that uses the visible and near-infrared bands of the electromagnetic spectrum. The NDVI index is also important to measure the periodical change of vegetation coverage and is related to Photosynthetically Active Radiation (PAR). The Panchet Hill dam situated in the margin of the states of West Bengal and Jharkhand was constructed in 1959 by impeding of the Damodar River which affects the surrounding vegetation in the catchment area. Main objective of this paper is to identify the change of vegetation pattern and abolition of green coverage of the area through NDVI technique.
