Analysis of Spatio-temporal Changes of Urban Land Use Using Remote Sensing and GIS: A Case Study of Bhubaneswar City, Odisha

Remote sensing and GIS technology are very useful in mapping of natural resources and urban studies. Urbanization being a dynamic force, its impact is seen in both spatial and temporal variation of urban land use. Most of the urban areas are increased due to urbanization and thereby creating urban sprawl. Bhubaneswar is the capital of the state of Odisha, between 20˚ 12' N and 20˚ 23' N latitudes and 85˚ 44' E and 85˚ 54' E longitudes. Land use /land cover maps were prepared by using satellite data of IRS-1D PAN (2000), Cartosat-1 (2005) and IRS-P6 LISS-IV (2010) and ground checks during field survey. The changes in urban land use pattern over a period of time were studied using multidate and multisensor (2000-2010) remote sensing data. The main aim of this study is to analyze the spatio-temporal changes of land use in the city as well as mapping urban sprawl. Based on the urban land use /land cover analysis, spatial growth of urban centers and the population have been projected for the different periods
