  This is the preprint version of our paper on ICONIP2015. The proposed
platform supports the integrated VRGIS functions including 3D spatial analysis
functions, 3D visualization for spatial process and serves for 3D globe and
digital city. The 3D analysis and visualization of the concerned city massive
information are conducted in the platform. The amount of information that can
be visualized with this platform is overwhelming, and the GIS based
navigational scheme allows to have great flexibility to access the different
available data sources.
