GIS IN ASSESSING TOPOGRAPHICAL ASPECTS OF HILLY REGIONS

Satish Kumar,V.K. Bansal

Abstract: Topography helps in identifying the areas of adverse locations that may increase development cost, delay construction besides creating the safety related problems. It further identifies areas that can be developed with minimum resources or to be restricted. Generally, on the basis of their knowledge and experience architects or engineers use 2D contour maps for analyzing hilly regions to locate infrastructure facilities. The applications of geographic information systems (GIS) help in analyzing topographical aspects by modeling topography. It provides 3D view of topographical information of the region where infrastructure facilities were proposed and likely to be located. In the present study various topographical aspects that are crucial for the locating infrastructure facilities were identified. A GIS-based methodology was developed for the analyzing the facilities of the campus of Jawaharlal Nehru Government Engineering College (JNGEC) Sundernagar, India, as a case study.
