Vegetal cover change detection based on Remote sensing and GIS study of Salem Revenue division, Salem district, Tamil Nadu, India

Author:S.Tamilenthi and R.Baskaran

Abstract:
The present study focuses on the role of remote sensing and geographic information system (GIS) in assessment of changes in vegetation cover, between 1973 and 2010, in the Salem revenue division, Salem district of Tamilnadu, India. The trend of vegetal cover changes over the time span of 37 years, was precisely analysed using Satellite images. The study revealed that the vegetal cover was 1325.99 and 1199.04 sqkm in 1973 and 2010 respectively. It was noticed that vegetal cover has decreased in 2010, because of the urban expansion led deforestation. It also revealed that the vegetal cover loss is due to expansion of cultivation and human interference. It is envisaged that the study would prove the usefulness of Remote Sensing and GIS in forest restoration planning.
