Criteria Analysis using GIS to Priorities the Slums

Due to rapid urbanization most of the people are migrating towards the urban. Urban regions in the developing country are facing enormous challenges. The well planned and managed urban region will provide better environment with good infrastructure and improved quality of life for their people. One of most important issues of the cities, especially in developing countries is the human settlement. Most of the rapidly growing cities keep on sprawling. Due to new migrants and also increasing poverty forced the urban poor to settle in unauthorized area of cities. This leads towards creation of new slums or expanding the existing slums. To make our cities sustainable and also to provide good environment for the urban poor, the slums need to be revamped. This paper is dealing with the slums which had been identified at zone four of Erode City, Tamil Nadu State, India. Erode city is one of the rapidly growing cities in Tamil Nadu. Totally 28 slums had been identified and mapped using GIS in the fourth zone. The tenability status of each slum and information about the basic facilities like drainage, road, water supply, condition of structures had been collected through the site visit. The collected attribute information had been mapped using GIS. Based on the importance of the criteria the weightages given had been assigned. The weightage criterion analysis provides the Prioritization Index (PI) for each slum. This guideline will be useful for the government to facelift the slums which need urgency.
