With the continuous urbanization of Hong Kong, the complexity and heterogeneity of spatial data in three- and temporal-dimensions raise new challenges to the traditional 2D geodatabases. Although the current OGC standard, CityGML 2.0, has already been tested in some cities in Europe, Singapore and Malaysia, its limitations make it cannot be directly applied to 3D GIS applications in Hong Kong. Meanwhile, smart city has been identified as one strategically important area for Hong Kong, and there is an urgent need to innovate corresponding key technologies, including 3D spatial data infrastructure.
This project aims to develop a 3D geodatabase framework for Hong Kong on the demand of Lands Department for its wide GIS applications for the whole Hong Kong, enabling its applications in effective and efficient 3D urban environment.
The developed geodatabase and the corresponding data capture system, SSDAS, will be widely utilized in many fields, including lands and resources surveying and management, civil engineering, autopilot, intelligent transport, highways maintenance and urban planning. These are the key areas that need spatial information infrastructure in Smart City. Although this system will be innovated in Hong Kong, it has a great potential to be further introduced to the markets in Mainland China and worldwide, due to its very practical features and technological innovations. |
