摘要

Recent land use/land cover estimates from Resourcesat-2 (2012) image and data about spatial distribution of land use/cover types obtained from outdated cartography. Land use/land cover pattern in the parts of Cuddalore district coastal areas. A supervised classification was carried out on the three reflective bands for the image individually with the aid of ground truth data collected during field trips of the classification results. Based on NRSA (1996) land use / land cover classification results are agriculture land, built-up land, forest, water bodies, waste land and others (Level I categories). However, after accuracy assessment six classes have been further classified into18 classes of Level II categories are classified. Crop land and fallow land (Agricultural land) was the most dominant class covering 34.97% and 25.43% followed by Villages (Rural) and Towns/cities (Urban) at 7.16% and 5.46% while Aquaculture Pond covered only 1.07% of the total area.
