1 IDBE Common conceptual framework and roadmap of collaboration in Spatial Standards for the Digital Built Environment

2 GeoBIM: 3D GIS in China Mei Xue: In my opinion, what matters most in the integration with BIM data is the semantic divergence and difference rather than the accuracy of data. Interoperability is the keyword of GIS-BIM integration for which cross-functional knowledge, experience and communication are crucial.

3 Future City Pilot (FCP), Phase 1 OGC in collaboration with bsi Accelerate standards process, requirements based 6/8 months project Pilot interoperability arrangements in Geo and BIM Quid IFC and CityGML? House rules: Pre-market conditions Non competitive Non operational environment Research In an interoperable environment using Open Standards

4 Scenario s Static 3D city models are easy to make Maintaining a city model is harder Need for validation of new components of the model Model validation (e.g urban planning rules) Connection with temporal data (e.g TimeSeriesML) Parts of a city planning tools Dynamic data to be linked to 3D models Flooding, solar potential / irradiation Sensors, IoT (e.g SensorThings) Graphics: IGN France

5 Scenario s Integration of city information with Dynamic model Goal: reduce winter death (urban services) Building humidity is related to illness Integrate sensor readings with city model Using CityGML and Sensor Web Enablement : Dynamizer Graphics: Greenwich and OSGB

6 Use case: Urban Planning and combined use of 3D urban data (BIM + Geo) Evaluation of BIM project in CityModel Assessing Urban planning Rules for validation Inputs BIM IFC project CityModel: CityGML (according to French IGN REF3DNAT profile LOD1/2/3 IGN National Reference data: Parcels, Roads, Outputs BIM project converted in CityGML Rennes Metropole / Bruz: provision of CityGML model from IGN Airborne imagery Use case contractor: University Of Melbourne

7 IFC to CityGML creates CityGML objects and assigns the information from corresponding ifc model elements creates the Building feature based on information from IfcBuilding element extracts the geometry of the room from IfcSpace element extracts the geometry of the room from IfcSlab element extracts the geometry of the roof from IfcRoof element creates the exterior MultiSurface boundary geometry of the building from the IfcWall element and tests for openings (will not include windows and doors, slabs) tests if the openings are Windows or Doors type. Will not include them in the boundarysurface and creates the window and door CityGML objects tests for the existence of Roof/surface. Will not include them in boundarysurface and will create the roofsurface object adds floorsurface from IfcSlab to the boundary of the project creates Door object from IfcDoor creates FloorSurface from IfcSlab creates RoofSurface as a MultiSurface BoundarySurface creates Window from IfcWindow and adds attributes

15 Integrated Digital Built Environment

16 White paper headlines Ensure that for domains in which OGC and bsi standards overlap (have touch points) that the conceptual models are identical Thereby to ensure that data can be seamlessly translated from an OGC standard to a bsi standard and vice versa Thereby offering the users trust and continuity of data between geospatial and construction domain

17 Three levels of coordination 1. Management (to meet 3 times p.a.). Include responsibility to develop business /operating models to suite joint initiatives. 2. Planning (to meet 4 times p.a.) To be between the Principal leads of OGC and the Infrastructure Room Steering Committee of bsi with liaison with the Management level. 3. Development (to meet 3/4 times p.a.) To be effected by working groups as appropriate under the guidance/ direction of the Planning level.
