Indoor maps: Simulation in a virtual environment

Navigating inside huge campuses can get quite cumbersome. In order to overcome this problem, Indoor mapping and modelling is introduced, which gives better sense of direction in a comparatively smaller environment. Indoor mapping and modelling includes creating an indoor environment, incorporating indoor localization techniques for tracing the user location and using a feasible way-finding algorithm for navigation in this indoor environment. This paper describes an Indoor navigation system for a college campus which uses the Global Positioning System (GPS) to create an indoor environment having Floor-wise distinction for the convenience of the user. Information acquisition was done by surveying the campus and with the help of rough floor plans (fire exit route plans) of each of the blocks. Once the information is acquired all the unessential artefacts are omitted from the acquired information.
