1 The (Rough) road to BIM- Geospatial standards Leif Granholm BIM ambassador

2 What is Structured Semantic data

3 BIM Graphics to objects Drawings geometry are graphics (appearance important) A Model consists of objects that may contain geometry and/or attributes (structure important)

4 Structured data Functional objects Physical objects Logical objects Abstract objects Objects describing process Schedules Resources Costs Quality assurance Tasks Work Approvals RFI:s Submittals

5 Semantic data on the Web Google Knowledge Graph W3C Linking open-data community project Web of Data (open, standard, structured decentralized) Facebook Open Graph

6 Semantic Web According to the W3C: "The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries Humans are capable of using the Web to carry out tasks such as reserving a library book, and searching for the lowest price for a DVD. However, machines cannot accomplish these tasks without human direction, because web pages are designed to be read by people, not machines. The semantic web is a vision of information that can be readily interpreted by machines, so machines can perform more of the tedious work involved in finding, combining, and acting upon information on the web.

7 Why structured data Technology development enables automatic use of data Robots (good example ping pong playing robot) Augmented reality taken to next step by Google Tango project Drones used for many purposes

8 Augmented reality & wearable computers Kopin Goldeni Google Glasses use an automatic connection to the cloud to provide access to enormous amounts of information, data and applications

9 Structured data, game changer Enables automatic consumption of received data by software Design progression level of development Analytics Logistics Remote control and operation Facility and asset management Digital services, navigation, product libraries Only imagination limits the use of data

10 Open DATA definition open DATA means that data is not tied to any specific tool, software or vendor Freedom to choose the tools best suited for the purpose Freedom to transfer data between tools Freedom to develop very purpose specific tools Independent of any platform Open standard data formats (IFC, CityGML, IndoorGML, InfraGML, KML ) are used for communication and interoperability

11 buildingsmart position on BIM BIM is about sharing data Open Structured Semantic Standard

12 Most important standards organizations GeoSpatial and BIM standards OGC Open Geospatial Consortium buildingsmart ISO TC/211 ISO TC/59 Technology standards W3C (World Wide Web Consortium) ISO TC/184 (Step)

13 Standardisation vs. Standards bsi S t a n d a r d i s a t i o n ISO CEN National Standards

14 What is the OGC and what is an OGC standard? Copyright 2012 Open Geospatial Consortium

15 The Open Geospatial Consortium Not-for-profit, international voluntary consensus standards organization; leading development of geospatial standards Founded in members and growing 38 standards Hundreds of product implementations Broad user community implementation worldwide Alliances and collaborative activities with ISO and many other SDO s University 24% Research 7 % NGO 10 % Government 18 % Commercial 41% Copyright 2013 Open Geospatial Consortium 14

16 OGC at a Glance Not-for-profit, international voluntary consensus standards organization; leading development of geospatial standards Founded in members and growing 38 standards Hundreds of product implementations Broad user community implementation worldwide Alliances and collaborative activities with ISO and many other SDO s Middle East 7 South America 2 North America 163 Africa; 4 Asia Pacific; 59 Europe 203 Copyright 2013 Open Geospatial Consortium 15

17 What is an OGC standard? A document, established by consensus and approved by the OGC Membership, that provides rules and guidelines, aimed at the achievement of the optimum degree of order (interoperability) in a given context. OGC Technical Committee Policies and Procedures. Derived from ISO definition EuroControl Aeronautical SkyView2 application Copyright 2013 Open Geospatial Consortium

18 What most people think about standards work!

19 Or How Many Others View Standards Copyright 2013 Open Geospatial Consortium

20 Standards Development is not easy! Requires collaboration on a global basis Requires concensus by many organizations Requires give and take Requires certified, repeatable process Copyright 2013 Open Geospatial Consortium

21 Most important OGC standards (of about 30) Content Conceptual models (f.ex Geometry ISO 19107) GML (Geography Markup Language) CityGML Services WFS (Web Feature Service) CWS (Catalog Service for the WEB) WMS (Web Map Service)

22 What is GML? Scope The Geography Markup Language is a modeling language for geographic information an encoding for geographic information designed for the web and web-based services

23 GML enables a vendor-neutral exchange of spatial data GML GIS X GIS Y Oracle File...

24 What is GML? Characteristics GML is based on XML technologies (W3C) XML, XML Namespaces, XML Schema, Xlinks implements concepts of the ISO series supports spatial and non-spatial properties of objects is open and vendor-neutral is extensible supports the definition of profiles (proper subsets) of the full GML capabilities

25 CityGML 3D and CityGML Copyright 2012 Open Geospatial

26 CityGML Application independent Geospatial Information Model for virtual 3D city and landscape models comprises different thematic areas(buildings, vegetation, water, terrain, traffic etc.) data model (UML) according to ISO 191xxstandard family exchange format results from rule-based mapping of the UML diagrams to a GML3 application schema ongoing standardization process in OGC CityGML represents 3D geometry, 3D topology, semantics and appearance In 5 discrete scales (Levels of Detail, LOD)

27 CityGML : 5 levels of details LOD 0 Regional, landscape model 2.5D Digital terrain model, 3D landmarks LOD 1 City / Site model Prismatic buildings without roof structures LOD 2 City / Site model Simple buildings with detailed roof structures LOD 3 City / Site model Detailed architectural models, landmarks LOD 4 Interior Model Walkable architectural models The same object may be represented in different LODs simultaneously

30 Indoor Spaces and Locations Semantic 3D city and building models provide (nowadays) the geometry and a thematic differentiation of the indoor areas (at least separation in building parts, floors and rooms) OGC standard CityGML Thematic differentiation already suitable for addressing, route descriptions and route tracking (homing) e.g. by room numbers

31 Indoor location/navigation Integrated indoor/outdoor navigation using OGC CityGML,IndoorGML, WMS 2012 Open Geospatial Consortium

32 What is WFS WFS An OGC standard to provide access to live structured semantic geographical (GML) data on the WEB XML or HTTP based encodeng of operations

33 History: Spin-off from ISO STEP project ca. 1994, alliance of 12 companies, Autodesk, AT&T, Honeywell, HOK and others Initially called International Alliance for Interoperability IAI Rebranded to buildingsmart 2005 buildingsmart is a private SDO (Standards Developement Organization) owned by its members.

43 Also need for other semantic information in BIM Terrain models Cadastral information Zoning information Utilities

44 Geospatial and semantic 3D Geospatial community getting aware of 3D technology Cadastre, terrain, design, Smart Cities New standards developed by OGC, CityGML, IndoorGML, InfraGML, KML (Google Earth format), 3D services in collaboration with web3d (webgl, X3D) New Urban Planning Domain Working Group in OGC

45 BIM GeoSpatial integration very hot topic Several standardization initiatives ongoing ISO BIM-GIS Ad hoc group OGC buildingsmart MOU and joint project about alignments Extending IFC for Infrastructure projects InfraBIM Roads, Railways, Bridges, Tunnels, Dams etc Joint project to develop conceptual schema of alignments for InfraGML and IFC Initiative to generate CityGML and IndoorGML from IFC UK BIM Task Group Very ambitious project by UK to use BIM technology in all public projects by 2016 VCON project by Dutch and Swedish traffic authorities to use BIM for whole life cycle of reoads and railways

46 InfraGML and IFC buildingsmart and OGC cooperation Cooperation around future of LandXML LandXML development nonexistent Autodesk and Bentley approached OGC to take over LandXML in 2012, bs openinfra also interested OGC started first Land Development DWG and then Land Development SWG to take on work First task to create conceptual schema of LandXML in UML by reverse engineering, mostly by Paul Scarponcini from Bentley Results from Frascati OGC meeting: -schema is too broken for compatible continuation -future with InfraGML and IFC for infrastructure in cooperation with bs, -scoping IFC for construction and GML for other purposes -name changed to Land and Infrastructure DWG/SWG 45

47 LandXML à InfraGML Proposal use case driven subset of LandXML functionality interoperability standard vs. negotiable template SDO support avoid possible legal issues enables OGC baseline consistency GML provides: feature model geometry support coordinate reference systems linear referencing TIN support compatibility with CityGML, TransXML
