Abstract
Information about infrastructure of the built environment is created and used at different stages throughout its lifecycle. Throughout the life of building, for example, different information is maintained through design, construction, as-is survey, facility management and possible changes of use as well as de-commissioning. Technologies to manage this information include Computer Aided Design (CAD), Geographic Information Systems (GIS) and Building Information Systems (BIM). These different types of system were often created to serve different purposes; hence it has proved to be difficult to truly integrate information flows between them. Recent advances in information management and open standards allow information about infrastructure to be stored and integrated along the above mentioned lifecycle. Open Geospatial Consortium (OGC) standards offer a proven suite of technology to store, query, exchange, visualise, integrate and manage this information and enable the convergence of systems dealing with infrastructure information.
This paper gives a brief introduction to the OGC technology stack but focuses on two particularly relevant areas: the exchange of data over web services and the CityGML standard, which offers a common, modular and extendable way of representing and exchanging data in the urban environment over multiple levels of detail. Based on Ordnance Survey®’s experience in information architecture and management, it is demonstrated how OGC standards can be used and implemented to increase value and usability of integrated and managed infrastructure data.
