Integrated landscape assessment and evolve perspective landuse planning for development suitability of Madurai metropolitan region 

Objectives: To create a GIS data base & to identify the trends in the spatial variation of the landuse over a period of 28 years (1969 - 1997). To assess and identify various classes of lands in terms of agricultural productivity and groundwater resources. Finally, to evolve appropriate landuse planning for the study area so as to aid the development Planners / Decision makers.
