Geospatial technologies offer an efficient and timely approach for mapping because of their wide area coverage, giving information about inaccessible area and timely repetitive coverage of the same area. In this study, on- screen visual interpretation was made to classify the land use/land cover particularly for the Janjhavathi river basin which lies in between the latitudes of 18045?? to 18061?? 30? North and the longitudes of 830 to 83029?? East. The identified land use / land cover features are agriculture, barren land, built-up area, dense forest, open forest, scrub forest, scrub land, gullied land, waste land, wet land and water bodies. Maximum area (37% of the total geographical area of the river watershed) is covered by open forest followed by gullied land and agricultural crop land (16%), deciduous forest (11 %), scrub forest (5%), agriculture fallow land (4%) and vegetation land (2%) while water bodies cover only 1 % of the Total Geographical Area (TGA). Further, an attempt has been made to analyze land use / land cover of Janjhavathi river basin keeping in mind the objective of developing the infrastructure with the available resources for the upliftment of the socio-economic conditions of the areas.
