Paper Abstract

In this paper, the concept of pseudo-3D visualization in mobile GIS is firstly defined, then a pseudo-3D visualization model is proposed and a simplified pseudo-3D projection transformation algorithm of building pseudo-3D map based on existed 2D vector data is designed. Furthermore the spatial data organizing and processing principles regard to limited hardware and software resources of mobile devices are introduced. To show the stereo vision effect of geographical scenes smoothly, preprocessing measures of pseudo-3D visualization and necessary 3D scene enhancement technology are applied. Finally, an agisNavigator project is implemented with the pseudo-3D visualization technology based on 2D vector spatial data in PocketPC and some experiment results are presented and analyzed.
