Deforestation is one of the main purposes for global warming and contributor of greenhouse effect. In recent years, Remote Sensing and Geographical Information System have the prospective to deliver precise information regarding terrestrial use and forest surface changes. The current analysis assesses the usefulness of high resolution satellite data and GIS techniques for analyzing the change of terrestrial use and forest surface change of Kotagiri Taluk of Nilgiris district for 2013-2016. The Landsat imageries of 2013 and 2016 were analyzed using software. A total of twelve land use regions were identified. The comprehensive study has revealed that the region under forest has increased from 973.34 km2 and 996.45 km2 and settlement from 44.29 km2 to 50.28 km2. The analysis shows that there was major alteration in the pattern of terrestrial use and deforestation of trees for urbanization. There has been a vast change in the strategy of forest surface and terrestrial usage throughout the region of Kotagiri which eventually results in loss of natural ecosystem.
