Abstract :

Detailed Relief information up to village level is prepared in the present investigation for Kolli hill, Tamil Nadu, India. The Kolli hill is a part of Central Tamil Nadu region and is taken up for the present investigation. The large scale data derivation is extracted using the contour data. The complete contours were traced from the Survey of India Totopsheet. The maps were registered in ArcGIS and the height values were given as an input in GIS. The attribute data information is added to prepare the relief information of the hill. The village boundary information is extracted from the Taluk map of the study area. The boundaries were digitized and overlaid to assess the relief variation in the study area. The results show that the relief is varied from 1200 – 900 m in the entire Perakarai Nadu, northern and southeastern parts of the study area. Similarly, the relief variation is extracted for all the villages.
