To generate a land use/land cover map for the year 2013 of the region, a
supervised image classification method was adopted using the maximum like-

signature file which contains the identified five classes of land cover. The five
classes that were selected are: built-up area (high density); built-up area;
cultivated land; Forest; and water body (Figure 7b).
