Visual Representation of Change in Vegetation Area of Dehradun, Uttarakhand, India using Normalized Difference Vegetation Index (NDVI)

The backbone of the Indian economy is the agricultural sector. Today agricultural fields are getting converted in concrete societies and barren lands. Due to heavy pollution in the environment, crops and fields are losing their productivity. So it's become very essential to have a continuous check on the crops and the agricultural region of the country. In this research work we have used the Normalized Difference Vegetation Index (NDVI) technique to check the vegetation area in the Dehradun region of the Uttarakhand, India. We have calculated the NDVI values for the three regions of the Dehradun using multi-spectral Landsat 8 data. We have found the values of NDVI in three different areas and concluded that the region of Dehradun is fairly good for crop productivity and agricultural purpose till date.
