  4. CAAD ISO standardised data exchange IFC Industry Foundation Classes IAI International Alliance for Interoperability www.IAI-international.com www.IAI-eV.de Application in multi-disciplinary data exchange between architects, planners, engineers of different domains and facility managers without loss of information GIS ISO standardised data exchange GML Geography Markup Language OGC Open GIS Consortium, Inc. www.OpenGIS.org Exchange and superposition of distributed GIS Data via Internet and other services (e.g. LBS), independent of the raised domain-specific data, geographical data, software technologies and data provider Additional Similarities The integration of relevant GIS data in the IFC data model has been going to be modelled and developed since October 2003 in Norway (s. IFG). The research group SIG 3D of "Geodaten-Infrastruktur NRW (GDI NRW)" has been working since 2001 on data exchange models for a 3D GIS

  5. 3D City Models for Planners • review of building applications • urban development with architecture models • visualisation of new projects • basic data for environmental protection • basic data for noise protection • ... buildings & digital terrain model: Freie & Hansestadt Hamburg, Landesbetrieb für Geoinformation und Vermessung

  6. 3D City Models for Architects • planning in urban context • space reference and coordinates • inclusion of traffic planning • inclusion of development data and wire catasters • studies about altitude of the sun, visualisation based on photogrammetry data buildings & digital terrain model: AEROWEST GmbH, Dortmund architectur model: onnen architecten, Hamburg Software: ArchiCAD

  7. Digital Terrain Model (DTM) with ArchiSpatial in ArchiCAD ArchiSpatial, ORACLE Spatial Connection with ArchiCAD • Geo-referenced data management by ORACLE Spatial >9.i • Composition of • Block Models with ALK attributes, envelops of buildings (photogrammetry) • architecture model (IFC) • Digital Terrain Model (xzy) with breaklines

  8. GIStec GmbH, SpinOff Fraunhofer IGD • Co-operation between ArchiCad and GIStec GmbH, a SpinOff from Fraunhofer IGD • Visualisation "On The Fly", transfer from ArchiSpatial • data base (ORACLE Spatial) supported viewer technology • GIS Meta Data Management

  9. GTA Geo-Informatics • Co-operation between ArchiCad and GTA-Geoinformatik GmbH • Data generation from photogrammetry, laser scans, ALK, etc. • perfect data transfer in ArchiCAD • visualisation of 3D City models
