Normalized Difference Vegetation Index (NDVI) Applications in part of South - Eastern Dry Agro-climatic Zones of Karnataka Using Remote Sensing and GIS

The Normalized Difference Vegetation Index (NDVI) is a simple graphical indicator that can be used to analyze Remote sensing measurements and to understand the vegetation of Chintamani Taluk area, this area covering under the South –Eastern part of Dry agroclimatic zones of study area. Compared between total Chintamani area and within the forest area analyzed. Basically the NDVI is a numerical indicator range from ?1 to +1 that uses the visible and near-infrared bands of the electromagnetic spectrum. In the part of study area grouped into different NDVI ranges -1 to +1. Chintamani taluk and Chintamani Forest area from LISS III data. Tanks area ranges between -1 and -0.05, Agricultural land between -0.05 and -0.16, Open land (Scrub Land) between -0.16 and -0.22 and Vegetation cover -0.22 and 1. Built up areas and impermeable surfaces which comes under very poor vegetation category had values less than 0.01009. Water areas have the lowest NDVI values.
