Land use (such as agriculture, pasture, or plantation) describes human use of land, while land cover (such as forest or desert) describes the biophysical characteristics of the land surface. This study seeks to utilize remotely sensed data and GIS tools to analyze the LULC in Udaipur city, Rajasthan to detect changes in the area by comparing images between 1972 to 2020. For developing a Land-use Land-cover map for the study area, two images of the Landsat series have been collected from the USGS (United States Geological Survey) earth explorer website. Each image has a resolution of 30m. A supervised classification technique was used with the help of a semi-automatic classification plug-in(Q-GIS). The study area has been classified into five broad categories - Forest, Agriculture, built-up, scrubland, and waterbody. In pre-processing of the image geometric rectification or image registration, radiometric calibration and atmospheric correction have been applied. The study reveals that there is a major decline in forest cover and agriculture area in these years while Built-up area rapidly increased. 20.85 percent vegetation reduced in Fifty years of time.
