Abstract

This paper introduces a Technique for extraction of Vegetation using normalized difference of Vegetation index (NDVI) using MATLAB, which is efficient and fast. NDVI has found a wide application in vegetative studies as it has been used to estimate crop yields, pasture performance and rangeland carrying capacities among others. It is often directly related to other ground parameters such as percent of ground cover, photosynthetic activity of the plant, surface water, leaf area index and the amount of biomass. This paper also includes change detection vegetation for different Years.
