Geospatial Database Development for Urban Planning Using Satellite Data under Gis Environment

Indian cities are experiencing an accelerated pace of growth since independence and are now emerging as centres of domestic and international investments in an era of economic reforms, liberalisation and globalization. This has created opportunities for technologists and planning professionals to guide and develop the process of planned development and management utilizing modern technologies. The availability of high resolution data from remote sensing satellites has revolutionized the process of thematic mapping and geospatial database creation, specially, in the context of urban and regional planning. Further, Geographic Information System (GIS) has emerged as a powerful tool in integrating and analyzing the various thematic layers along with attribute information to create and visualize various planning scenarios for decision making. The increasing demands in urban planning and management sectors call for integrated application of remote sensing and GIS for sustainable development of urban areas. The present work deals with the development of geospatial database for urban planning of Allahabad city of Uttar Pradesh State in India through the use of satellite data and other collateral data under GIS environment. IRS-1D LISS-III digital data has been used for the extraction and analysis of the land utilization pattern of Allahabad city. The various thematic layers generated include land use pattern, road network, water supply, solid waste disposal, soil map, ground water potential map, etc. and these have been integrated with socio-economic and demographic data of the city to model the urban growth of the city.
