![]() ![]() The use of open standards (CityGML and LandXML) and services (WFS) will enable stakeholders to use the data immediately without revamping their existing computer systems. The 3D map data and CityGML models will be shared among government agencies and partners and will support Virtual Singapore and Singapore's Smart Nation initiative which involves innovative and comprehensive use of technology and research to improve quality of life and business opportunities. Using Bentley Map, the project team created, maintained, and disseminated 3D information directly from Oracle Spatial and provided multi-user access to the database through direct connection and Web Feature Services (WFS). The challenge was managing and updating the data. Singapore Land Authority employed multiple rapid mapping technologies such as oblique imagery, airborne laser scanning, mobile laser scanning, and terrestrial scanning, resulting in more than 50 terabytes of data in multiple formats. ![]() The project involved capturing large amounts of data, creating 2D and 3D datasets in several data formats, and supporting the interoperability of the data and management of datasets in a single repository. The project encompassed all of Singapore, an area of more than 700 square kilometers. The Singapore Land Authority led this SGD 8 million government initiative to create and maintain a high-resolution 3D map of the country.
