STUDY ON EMERGING PROBLEMS RELATED TO SPATIAL VARIATIONS IN URBAN LIVING CONDITIONS

This study illustrates the use of remote sensing and geographic information system (GIS) techniques (i.e. geospatial techniques) for mapping and evaluating the emerging problems which is related to spatial variation in urban living condition in Hyderabad district, Telangana State. The expansion of Urban has brought serious losses of different types of land like water bodies, agriculture land, vegetation land etc. For a variety of urban environmental issues like increased air pollution, runoff and subsequent flooding, increased local temperature, deterioration of water quality, etc Urban sprawl is responsible. In this work we have taken Rangareddy District, Ghatkesar Mandal as case to study the spatial variation and land cover change that took place in a span of 05 years from 2005 to 2015. Remote sensing methodology is adopted to study the geographical land use changes occurred during the study period. Satellite data- Resource Sat with LISS-IV and cartosat -1 with 2.5 m stereo images were taken into consideration for preparing hybrid products. Image pre-processing, is done first later supervised classification has been performed to classify the images in to different land use categories. The accuracy of the Classification is also estimated through field surveys. This paper also highlights the changes in other land cover categories during which causes emerging problems the period under analysis. This study may provide reliable inputs for urban planners who are planning to provide basic amenities such as transportation, water, sanitation, electricity, etc.
