Abstract

This paper addresses on our practices on the recent development in geo-spatial information technology. Specifically, these include a) spatial data capture technologies based on high resolution satellite imageries and laser scanning technology; b) modern GIS data modeling techniques - towards three-dimensional and dynamic data modeling solutions in GIS; c) spatial information distribution technology based on mobile computing and Internet technologies, and finally d) from certainty-based to uncertainty-based geo-spatial information science.
