TOWARDS 3D LBS- CHALLENGES AND OPPORTUNITIES

By F. Wang A and J. W. Liu B

Abstract

Geospatial locations are increasingly considered as a very important factor for providing diverse kinds of public or proprietary services, such as map services including the real time navigation function, and social network services such as the buddy-finding feature. These services are always based on the geospatial locations and therefore named as Location Based Services (LBS). LBS as a special stream of GIS have been widely researched in the GIS community. As the rapid developments of mobile devices, wireless networking, location sensing techniques and other ICT, LBS have boomed in the industry and achieved great revenues all over the world. However, most existing LBS can only deal with two dimensional geospatial data and offer related 2D geospatial services. They lack in supporting three dimensional datasets as well as 3D services. To use the existing and newly emerging 3D datasets and implement different 3D based LBS systems based on existing 2D LBS systems or from scratch, some important issues have to be investigated. This paper discusses core components of LBS in detail and also provides a prototype for demonstrating the methodology of upgrading a 2D LBS system to the 3D LBS one. 1
