Morphometric Analysis of Chamundi Hills, Mysuru, India Using Geographical Information System

The article attempts to determine and understand the morphometric form of Chamundi Hills which are in the south-eastern part of Mysuru city. The study was based on the Mysore City Guide map (part of Toposheet No. 57 D/11) published by the Survey of India in 1976 and it was prepared within the geospatial software ArcGIS 10.3. The study was made with the grid method followed by interpolation method in determining relative relief, dissection index, and ruggedness index. Slope analysis was one of the extensions of relief morphometry which was developed and designed using Arc GIS. The slope analysis tools covered slope in degree, slope in percent, slope aspect and slope curvature. The study revealed that the Chamundi Hills had a hexagonal shape with steep slopes and were highly dissected in the northern and in the western sides. The study indicated that the hills were in the mature stage as per the geographical cycle of erosion. Maturity in the cycle of erosion, steep slope, high dissection, high slope in degree and in percent and high concavity might hinder the developmental programme, with exception on the eastern and on the southern parts of the Chamundi Hills.
