ELEVATION IDENTIFICATION IN A PART IN CENTRAL INDIA WITH GIS AND REMOTE SENSING

Study is about the granitic terrain and most populated area of Bundelkhand a part of central India. Incorporation of contour lines on 25m interval in Arc GIS and ERDAS imagine environment using IMSD 1995 guidelines by NRSA has been carried out for slope analysis and determination of seven slope elements. The area has been identified because of its acute drought prone conditions. The main sources of water in the region are based on two major river that is Betwa, Dhasan and rainfall. Jhansi district is in the southwestern part of the Uttar Pradesh covering 5024 sq. km area. The district comprises with eight blocks. Slope plays a vital role to define the landform of a geographical region. Sixteen slope elements and six slope class has been identified in the given region to establish the relation between slope and landform for further studies. While identifying slope classes on 25m contours, both manual and automatic approaches in ArcMap and ERDAS Imagine were used using standard methods applying mathematical approach. Using toposheet, IRS imagery, and SRTM DEM, several thematic layers such as contour, TIN, aspect, elevation, and slope were created. Remote Sensing and Geographical Information System (RS & GIS) technology serves as a watershed moment in thematic map development and integrated analysis for natural resource management and monitoring.
