UGNS: A UBIQUITOUS GIS BASED NAVIGATION SYSTEM USING AUGMENTED REALITY TECHNOLOGY AND MAP MATCHING ALGORITHM

Existing navigation systems are needed spatial knowledge to interpret navigational instructions. People without having spatial knowledge cannot use these systems. So there is a need to design user-friendly and easy-to-use navigation system that any user can use in any place at any time. In this paper, a ubiquitous GIS based navigation system is designed using Augmented Reality (AR) and map-matching for smartphones. AR which combines real and virtual world creates interactive environment to enhance user perception. Map-matching is to reduce technical errors of positioning sensors of the smartphones. The designed system can provide the right navigation service to any person without any time and place limitations.
