Smart Cities for a Resilient Future

(Submission #395)


Human, natural and physical systems interact in space and time and digital systems in cities will become increasingly diverse and numerous, with many owners. Cities thus 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. This presentation (based on the OGC Future Cities Interoperability Pilot) will show how cities can begin to reap the benefits. The objective of the pilot is to demonstrate how use of open data sets coming e.g. from INSPIRE, 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. The use of BIM models encoded in IFC will become mandatory for important building projects. Urban planning authorities check the conformance with urban rules planning using an automated process. For verification, an analyst easily views the building project within the existing 3D model of the city. BIM data is added to the existing 3D City models database, according to local city rules, with mapping to the various levels of detail. The BIM data is stored with links to the geospatial data (at feature level) and BIM data.   City Data navigation, search & reporting applications enable simultaneous queries across a number of linked data sources. These data sources are maintained, as is the vase is most cities, by different information systems in separate departments responsible for such things as housing surveys, Socio-demographic data, street cleaning, lighting, drainage, public roads, parks, 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. Unifying the existing and future information for each of the different areas, included within urban services, using standards-based interoperable web services will give the city the ability to do ‘cross urban service’ analysis and visualize the results in a 3D environment that helps the decision makers of the city.
