Pollution Prevention study using Remote Sensing and GIS: A model study from visakhapatnam district, Andhra Pradesh

摘要

The present Studies Involves to develop a base line data and existing environmental conditions to the GIS database to holistically assess and manage environmental and non-environmental resources used by Industrial investors and other land and water users. The implementation of the Geographical Information System (GIS) will bring positive benefits through the generation of information and creation of digital databases with information on Air, Water Quality, Health and Hygiene and streamlines the decision making process. IRSP6, LISS-IV geo coded Remote sensing Satellite data and top sheets from Survey of India (SOI) are acquired for primary analysis. The present study has been carried out in nine (9) mandals namely Nakkapalli ,Elamanchilli,S. Rayavaram, Achchutapuram, Rambilli, Anakapalle, Munagapaka, Kasimkota, Paravada of Visakhapatnam District, covering an area of 1355 Sq.km. The study area is located between north latitudes 17 19 and 17 46and east longitudes 8235 and 8310 and is covered in the survey of India topographical map numbers 56H65 K/10,11,13,14,15M 65 O/1 and 2. Using Visual Interpretation technique different thematic maps are prepared like land use/land cover, base map, village information, drainage maps These thematic maps were scanned and digitized using AutoCAD and converted into GIS. Topology is created by linking the spatial data file and attribute data file. GIS overlay analysis derived maps like surface water Table, surface water use, surface water quality, was carried out to find out the above parameters pollution lodes in the study area, Finally integrating of the all the above maps sensitive zone maps has developed. This kind of studies is very useful for Pollution Prevention in industrial areas and also useful for the planners decision makers for management and monitoring of industrial areas.
