Land Use and Land Cover Change Detection Using Geospatial Technology

Land use and land cover has a leading role in the part of urbanization. As the rapid urbanization led to various activities in a region and these changes generally takes place in the agricultural land. The satellite imageries LANDSAT TM (1990 and 2010) data are used. The scales are 1: 50, 000. From 1990 to 2010 covering a period of 20 years, the aerial distribution of the land use and land cover changes has been observed. The changes were identified, in which the decrease of Agricultural land, open Scrub and Water bodies and increase of Built-up land, Fallow land and current Fallow land. The land use and land cover maps are prepared by using GIS software to evaluate the changes and it showed strong variation. Image pre-processing and supervised technique analysis will be performed to classify the images into different land use categories. Thus, the information of urban growth, land use and land cover change are very useful to local government, urban and town planners, in order to have a planned city with reduction of congestion, pollution and to achieve a sustainable development of the city.
