A study was conducted for Identification and Management of Special Economic Zone (SEZ) in Sriperumbudur Taluk of Tamil Nadu, India using GPS & GIS Analysis. In this study the thematic maps of Landuse / Landcover map, Road network maps (LISS IV) and Soil map has been prepared by using ArcGIS 9.2 software. The landuse / landcover map of 2003 & 2007 were analyzed and delineated the industrial area & built-up area. In the year 2003, the aerial extent for the SEZ in the study area is 1.2sq.km and it will be extended upto 1.4 sq.km in the year of 2007. The change detection is mostly acquired in Agriculture land & water bodies. The extended area was converted in to shape file format and imported into ExpertGPS software and validated by using Google Earth. During the validation 90% of data exactly merged with Google Earth features. The built-up area of expected Multi-storey building development in that region has been analyzed through GIS software. For increasing Multi-storey building the proportionate development of SEZ was delineated with considering population strength, Water Requirement and Sewage estimation at different FSI conditions. The future population can be estimated at different methods of Arithmetic method, Geometric method, Incremental Increase method & linear method from 2011- 2029 with different periods like (2001-2011 and 2011-2029) and compared with previous decade (1991-2011). The growth rate of population was found out 25.8% previously, 29.2% as presently and future it will be expected to change up to 34%. For considering population estimation, other requirements like water and sanitary are also predicted and prepared the thematic map for different FSI. The maximum permissible limits of population at different FSI for SEZ are 84247, 138769 & 196596 respectively. The water demands for three FSI values (1.5, 2.5 & 3.5) were found to be 8888305, 18733815 & 26540460 lpd respectively and the sewage capacity was found out from 7582230 lpd (1.5 FSI) to 17693640 lpd (3.5 FSI). This study has been undertaken in order to understand the impacts of SEZ likely to be created in the physical and social infrastructure in the study area and also to be suggested the remedial measures required to be undertaken to meet the requirement for future population.
