Urban Sprawl and its Impact on Urban Environment

This Paper an attempt has been made to examine the urban sprawl of Gorakhpur City through the land sat Images .Remote sensing and GIS to analyze the urban sprawl mapping and detect changes of urban sprawl of Gorakhpur city through different year.Satellite data are found to be useful in mapping and quantifying the extent of urban area in different time periods.New urban region development growing largely towards north, north-west and south-west direction along the main transport route of the city.New urban development occurs mainly on vegetation and agricultural land.This study provides a methodology for better estimation of urban growth and population using various land sat images with time.Geographical information system(GIS) and satellite images have been used in this study to provide spatial inputs and test the statistical model describing growth.This is useful for the urban planning in Developing Countries where land use data is not available regularly.GIS and Rescan help a lot in monitoring urban sprawl compared to Conventional technique
