Spatial and Temporal Variations of the Obtained Database of Environment Pollutant using GIS and Remote Sensing - a case study of Metropolitan City of India

摘要

The present paper is focused on the analysis of the spatial and temporal distribution of outdoor noise in Mumbai City, India. The database is built by primary field survey. A total number of 200 samples were surveyed, out of which 70 samples are selected for the preparation of isodecibel maps in the present paper. For the latest landuse and vegetation of Mumbai, satellite imageries are used and for air quality, isoline maps of MMRDA prepared on Arc Info are used. The maps are prepared by using GIS techniques like Map info, Autocadd and Arc view. Several overlays of vegetation, relief, population density, landuse, traffic corridors and air quality is attempted in this paper along with analysis and concluding notes.
