Assessment on Land Use Changes in Coimbatore North Taluk using Image Processing and Geospatial Techniques

The landuse and land cover is important for many planning and management activities and is considered an essential element for modeling and understanding the earth as a system. The base map of Coimbatore North Taluk has been created using Survey of India toposheet for the year 1988. The current landuse map was prepared by using ASTER Satellite imagery in open source software environment. The landuse changes were predicted by using image processing and GIS analysis. The results indicate that severe land cover changes have occurred in agricultural (-19%), urban (234%), waterbodies (-0.7%) and forestry (-4.5%) areas in the region between 1988 and 2011. It was seen that the landuse changes were mostly occurred in urban areas.
