Abstract :

Changes in land use Land cover is a dynamic process, which vary with space and time and it become a central component in current strategies in managing natural resources and monitoring environmental changes. Digital change detection is the process that helps in determining the changes associated with land use and land cover properties with reference to geo registered multi temporal remote sensing data. The objective of this paper is to analyse the land use land cover changes in Guwahati city of Assam Using multi temporal remote sensing data LANDSAT TM 1991, and LANDSAT ETM 2009. The city has witnessed a very high rate of growth of population during this period, which leads to various problems like growth of slums, urban sprawls, deforestation, environmental degradation etc. The detection of Land use change ¬of Guwahati city for the last two decades was analysed by supervised classification, where 8 land-use classes have been selected and analysed using Eradas Imagine software. The result show changes in the agricultural land and forested area in fringe areas of the city and open land within the city and a great expansion of settlement.
