“DEM Based Topographic Survey of Vaijapur Taluka Using RS and GIS”

Vaijapur is one of taluka comes in Auranagabad district in Marathawada region also suffering from the same problem of irrigation and agricultural productivity. Study area is located in Vaijapur taluka, Aurangabad district in Maharashtra, India. State and situated at the latitude of 19°40’ to 20°15’ north and longitude of 74°35’ to 75°00’ east covering an area of approximately 1510.5 sq. km and fall in Survey of India Toposheet No. 46 L/16 and having population 311371 as per 2011 Census. Vaijapur is located 514 m (1,666 ft) above sea level on the western margin of the Deccan plateau. The objective of the work is to study and to prepare various map like land use land cover, types of soil, contour, aspect, hill shade etc. using GIS and give the suggestions of sustainable development of agriculture in Vaijapur. The software use for the work is ArcGIS 10.3 which is developed by ESRI. The average annual rainfall in that region is approximately 634 mm by this rainfall amount of water collected within the taluka boundary was 974490 million litres From the study of land use land cover map it was found that the ratio of barren land to agricultural land is unity and area contributed by water bodies is negligibly small (0.102% of total area). Barren land is 798.82 km², agricultural/vegetation is 730.50 km², water bodies is 1.580 km² and residential 6.131 km². About eight types of soil are found in Vaijapur taluka and type second and seventh have dominant area extent. From study of geology it is showed that only two types of rocks are found in the area. First is basalt and second is alluvial but basalt rock formation is major. Basalt area is 1525.948921 km², alluvial area is 4.100 km².
