Network Analysis using GIS Techniques: A Case of Chandigarh City

Abstract

ArcGIS based Network Analysis provide multiple solution aspects for a variety of problems pertaining to spatial networks include finding the most efficient travel route, generating travel directions, locating the closest facility, and defining service areas based on travel time and distance covered. The present study tries to analyze the potential use of network analysis in defining the optimal service area of different services such as hospitals, schools and fire stations of Chandigarh city. Google earth image of Chandigarh city has been used for this study; it was then geo-referenced. Digitization was carried by using Shape file generated for different analysis. The network analysis tool was used to measure the efficiency of services in terms of time and distance. It also help in analyzing the gap existing in the spatial allocation of these services in city area and whether the existing resource allocation is good or bad in term of efficiency of these services.
