| Summary: | Since 2014, the Land Survey Division of Singapore Land Authority (SLA) has spearheaded a Whole-of-Government (WOG) 3D
mapping project to create and maintain a 3D national map for Singapore. The implementation of the project is divided into two
phases. The first phase of the project, which was based on airborne data collection, has produced 3D models for Relief, Building,
Vegetation and Waterbody. This part of the work was completed in 2016. To complement the first phase, the second phase used
mobile imaging and scanning technique. This phase is targeted to be completed by the mid of 2017 and is creating 3D models for
Transportation, CityFurniture, Bridge and Tunnel. The project has extensively adopted the Open Geospatial Consortium (OGC)'s
CityGML standard. Out of 10 currently supported thematic modules in CityGML 2.0, the project has implemented 8. The paper
describes the adoption of CityGML in the project, and discusses challenges, data validations and management of the models. |
