Preparation of various thematic data such Land use and Land cover using Landsat data.Create a land use land cover map from satellite imagery using supervised classification.Find out the areas from the classified data. The study is based on secondary data, the satellite imagery has downloaded from GLCF (Global Land Cover Facility) web site, for the study area (path 143 row 53), the downloaded imagery subset using Imagery software to clip the study area. The clipped satellite imagery has used to prepare the land use and land cover map using supervised classification. The land use and land cover map clearly shows that area of crop land is higher than others. Land with or without scrub has 605 sq km area it occupies second place in this district, Plantation has 309 Sq Km and Fallow land has 227 Sq Km, Dense forest occupies 160 Sq Km while rest of other have low than 100 Sq Kmarea.
