Abstract
Remote sensing and GIS technologies are very much useful for finding the Land Use/Cover maps. This is the paper which deals with the Land Use/Cover Change (LUCC) especially to urbanization in Chennai metropolitan area, India for past two decades till present. Chennai is the fourth largest metropolitan city in India with area of 1189 km2 with 4.68 million of population, which is developing rapidly into urban in past few decades. There is heavy need of urban planning for future in Chennai. This research will be a support for urban planning of the future. The Land satellite data for three decades (1989, 2000 and 2012) and Digital Elevation Model (DEM) for present were collected with 30 meter resolution. Preprocessing of all images was completed. Image classification for mapping LUCC was performed by supervised classification through the maximum likelihood classification for four classes: Water, Rough land, Crop land and Urban. An accuracy assessment has been checked to find the accuracy of the Classification and the overall accuracy is about 87%. Transition probability matrices were calculated for all three time points and compared with each other (1989 with 2000, 2000 with 2012). The result shows that the increase in Urban and decrease in Rough land. Slope map has been created from DEM. Analyses of neighborhood effects were done to find the probability of land changes due to existing urban cells, which is calculated for each cells surrounded by its three neighborhood cells. Analyses of slope effects for urbanization was done by comparing the slope and the possibilities of change from Rough land and Crop land to Urban. A simple model structure for simulation was created using VBA and GIS. The model applies the neighborhood effects which are similar to Cellular Automata but in this model it is modified by slope effects. Using the simulation urban map was predicted for future trends. These predicted urban maps will provide critical input to resource management and planning support applications, and have substantial social and economic benefit for metropolitan planning and development.
