Lightweight 3D Seamless Spatial Data Acquisition

With the continuous urbanization of Hong Kong, the complexity and heterogeneity of spatial data in 3D and temporal-dimensions raise new challenges to the traditional 2D geodatabases.

There are 2 deliverables in this design: 1) 3D geodatabase framework design, and 2) Lightweight 3D Seamless Spatial Acquisition System. For the framework design, it has the capability to provide comprehensive topological relationship modeling, detailed 3D geospatial modelling, semantic & geometry modelling and interactive geo-visualization in 3D. While the SSDAS can integrate multi-sensor with an all-in-one mobile platform and light in weight.

This application will be applicable for geospatial modelling on complex city environment like Hong Kong.
