Geoinformatics for the physiographic and land use/land cover mapping of Siwani area, Bhiwani district (Haryana)

Abstract

Geoinformatics is a modern technology playing very important role in the study and monitoring of the natural resources in any part of the world. This technology can be used for generating valuable information about the land use/ land cover (LULC) changes, physiography, forest cover, vegetation type and landforms of any particular area. The study area falls in the toposheet no. H43V9 and three maps were formed such as base map, LULC map and physiographic map. Information collected from these maps will help in land use planning at micro level. The main aim of this paper is to determine and quantify the effect of different aspects responsible for deteriorating the agri-economic importance of land. The paper also establishes the relationship between landforms and land-use. The relation is not one-to-one but rather one landform may be under several land use types and vice versa. The results revealed that the area under landforms of Siwani block was found 676.36 km2, dominated by plain area (582.13 km2) followed by sandy dunal area (42.35km2) and 475.91km2 under land use/land cover with maximum of its area under fallow land (304.06km2) and (82.37km2) area under cropland. The maps prepared will furnish first-hand information to authorities and devisers about the land use land cover and landforms of the study area.
