Use of Remote Sensing and GIS Techniques for Land Use and Land Cover Mapping of Tuticorin Coast, Tamilnadu
Journal Title: Universal Journal of Environmental Research and Technology - Year 2012, Vol 2, Issue 4
Abstract
The study area (8° 43' - 8° 51’ N latitude and 78° 5' - 78° 10' E longitude) falls in the east coastal belt, west of Tuticorin, Tamil Nadu, India. Land use and Land cover is an important parameter for developmental planning. In the present study an attempt has been made to generate the land use and land cover map from Satellite (IRS) 1C, linear image self-scanning (LISS) III of geocoded with UTM projection, sheroid and datum WGS-84, Zone North 44 generated from the total bands 4 on a 1:50,000 scales, was used unsupervised classification and topographical maps, and enhanced for better interpretation. A process of integrating remote sensing techniques and field data to accurately map landuse and land cover of the study area catchment is described. Major problem with the study area can be identifies as are (i) Rapid Growth of Population and (ii) Unplanned growth of the city both horizontally in all direction and vertically also. Field observation shows the current status and issues of coastal environmental problems. Finally, a maximum likelihood classifier was applied to classify the satellite images. Six major landuse classes were identified and mapped for the study area. These are: Cultivated land, Salt pans, Barren land, Shrubs and Water bodies. The study observed that cultivated land is dominant in Tuticorin and its surroundings followed by salt pans. The study recommends the use of satellite imageries for future environmental monitoring studies.
