4 Current 2D Maps Are Not Adequate Not able to fully represent the real world Low resolution and few details

5 Growing Needs for 3D Information Development Planning Underground Infrastructure Urban Heat Island 3D Geological Map DTM for Flood Management Solar Potential Study Underground Utilities Urban Air Flow Dynamic Telecommunication Coverage

6 Smart Nation Singapore is building the World's first Smart Nation by harnessing technology and gathering insights from data to the fullest with the aim of improving the lives of citizens, creating more opportunities, and building stronger communities. Measurement + Prediction = Performance

7 We Need 3D Map Data As-built 3-dimension Smart Data Model High Resolution Reliable Up-to-date 3D Map Data Applications National Security Urban Challenges Underground Development Climate Change Adaptation Development Planning

24 Data Management Strategies Collect once, use by many 1. Single point of truth (SPOT) is managed and maintained in Open Source Data Format and Data Schema Embrace Open Geospatial Consortium (OGC) standard (e.g. CityGML) Ensure government data is technology-independent 2. Data standard Establish 3D data standard to ensure interoperability and support inter-agency data sharing Actively contribute and influence international 3D standard 3. Multiple source / technology

25 CityGML CityGML is an XML base data format CityGML captures 3D geometry, 3D topology, semantics, and appearance in 5 discrete scales (Levels of Detail, LoD) LoD0 Terrain Model Source: Thomas Kolbe LoD1 Block models with no roof structures LoD2 Explicit roof structures LoD3 Detailed architectural models LoD4 Interior modelled

26 Static Laser Scanner Rapidly capture very high resolution 3D data on ground level Capable of going indoor Capable of integrating color from images

27 3D Point Cloud State Property
