Human, natural, and physical systems interact in space and time, and the digital systems in cities will become increasingly diverse and numerous, with many owners. Cities therefore need an open, vendor-neutral standards platform for communicating spatial and temporal data. Many of the longstanding technical boundaries separating indoor, outdoor, underground and atmospheric information have been overcome.

 

By demonstrating capabilities employed in a holistic urban planning scenario, the Future Cities Pilot will show how cities can begin to reap the benefits. The objective of the OGC pilot project is to demonstrate how use of, CityGML data and IFC data together can provide stakeholders with information, knowledge and insight which enhances financial, environmental, and social outcomes for citizens living in cities. CityGML is an open data model and XML-based format for the storage and exchange of virtual 3D city models. Industry Foundation Classes (IFC) are the open and neutral data format for an open BIM environment.

 

In the scenarios, the use of BIM models encoded in IFCs is mandatory for important building projects. The urban planningauthorities check the conformance with urban planning rules using an automated process. For verification, an analyst easily views the building project within the existing 3D model of the city. The BIM data is added to the existing 3D city model’s database, according to local city rules, with mappings to the various levels of detail. The BIM data is stored with links to geospatial data and BIM data.

 

City data navigation, search & reporting applications enable simultaneous queries across diverse linked data sources - the unified urban and social services. These data sources are maintained, as is the case in most cities, by different information systems in separate departments responsible for such things as housing surveys, socio-demographic data, collection and street cleaning, lighting, drainage, public roads, parks and gardens, transport and telecommunications networks, telephone, electricity, water and gas and various other city datasets. Linked data access to multiple legacy collections of spatial data is demonstrated in use cases involving environmental simulation, disaster management, and training simulation.
