Abstract :

An attempt has been made to analyse the landuse and landcover change detection in Thottiyam block of Tiruchirappalli district using remote sensing and GIS techniques. The total area of the study is 278.02 sq.km. It lies between the long 78o 10’ E to 78^o 25’ E and Lat. 10^o 50’ to 11^o 10’ N. This area has a multivarious land use. The satellite imageries LANDSAT 5TM (1990), LANDSAT 7ETM (2000) AND LISS 111 (2010) data’s are used and the scale is 1:50,000. It is located in the central part of Tamil Nadu. Landuse and Landcover change detection maps were generated and classified into agriculture land, built–up land, fallow land, natural vegetation, river sand, water bodies, and scrub without scrub land for the year 1990, 2000 and 2010 based on NRSA classification. Each landuse and landcover has been from change to have positively and negatively for the three decades, especially agriculture land, sandy area, natural vegetation and fallow land, which is about 19.62, 6.56, 13.16 and 14.91 percentages respectively. These images were taken for compå the classifications. The Landsat 5TM and 7ETM images were taken from GLCF. For more accurate perception and understanding the LISS 111 image.
