A Road-Based 3D Navigation System in GIS: A Case Study of an Institute Campus

Abstract

A user-controlled navigation system is one of the important aspects of human-computer interaction. Finding best path from one location to another and navigating through that path has been a great concern in the geo-virtual navigation. Earlier studies on the geo-virtual navigation systems mainly focus on navigation and visualization, but lack in geo-spatial analysis. Geo-spatial analysis is the domain of geographic information systems (GIS) in which 3D geo-spatial information is used for navigation, geo-visualization, and geo-spatial analysis. The present study deals with wayfinding in the road network of the campus of National Institute of Technology (NIT) Hamirpur, India, in a hilly terrain. It facilitates perform various types of geo-spatial analyses on the road network and virtual travelling in a 3D space.
