1. International Association for Mathematical Geology XIth International Congress Universite de Liege, Belgium Tuesday 5 th September 2006 The IUGS-CGI international geoscience information interoperability testbed Tim Duffy BGS Edinburgh, trd@bgs.ac.uk: +44 (0) 131 650 0378trd@bgs.ac.uk E.

2. GeoSciML = GeoScience Markup Language An international (IUGS) application of GML3.1.1 (an XML schema= Geography Markup Language) for sharing geologic information Data Model Working Group IUGS Commission for the Management and Application of Geoscience Information (CGI)

3. Outline  Exchanging geologic map information Provide geologic map data via geospatial web services  Developing a standard GML data format IUGS development of GML application specification (GeoSciML), testbed  Future Activities public release and evaluation  Demonstration

5. Motivation  International geologic data interoperability  Mature open geospatial standards (OGC, ISO)  Commitment of data providers to provide data to users in a standardized format  Evolving distributed information system environment CanadaUSAUKFrance Germany Korea Japan Denmark Sweden Finland NetherlandsAustraliaPolandCzech

6. Framework  Multiple levels of interoperability systems syntax schematic semantic interoperability GeoSciML (data structure) Ontology/Vocabulary (data content - information) Geoscience GML (data language) WFS, WMS, WCS, … (data systems) OGC Standards

7. Approach:  International consensus  International consortium of major providers of geologic map data  IUGS Commission for Management and Application of Geoscience Info.  Face-to-face meetings and Twiki  Start with those geoscience objects that form the main components of a geological map (geological units, faults, contacts, and their defining concepts) – expand later to other geoscience domains  Re-use, revise and extend existing standards  GML (OGC)  NADM  XMML  others  Test with ‘common off-the-shelf software’ (COTS)  National map databases  Industry partnerships

8. Approach: GeoSciML design  Conceptual  Logical  Physical GML schema design conceptual model: no GML logical model: GML-UML physical model: XML Granite, syenite, volcanogenic sandstone, conglomerate, minor trachyte lava Mount Leinster Igneous Complex typicalNorm <value codeSpace="http://www.iugs- cgi.org/geologicAgeVocabulary">Triassic <value codeSpace="http://www.iugs- cgi.org/geologicAgeVocabulary">Triassic <value codeSpace="http://www.iugs- cgi.org/geologicAgeEventVocabulary">intrusion physical model: GML-XML UML to GML

9. Activities: workgroup progress 1. Nov. 2003  15 countries represented; agree to share info. using OGC web services  Form Data Model Collaboration Working Group (DMC WG) of IUGS-CGI 2. Dec. 2004  review existing models  set up teams to model geological units, materials, structures, boreholes  showed Testbed 1 at IGC32 Florence August 2004 for WFS boreholes 3. Aug. 2005  GeoSciML beta, specified Testbed 2, sharing geologic maps  GeoSciML 1.0 in Jan. 06 4. April 2006  GeoSciML 1.1 revisions, clarify Testbed 2 use cases  GeoSciML 1.1 May 06

10. Activities: Testbed 2 – What is a Testbed?  In the context of OGC's Interoperability Program, a testbed is a collaborative activity in which sponsors provide interoperability requirements and financial support and technology providers team to develop prototype interoperability interfaces, protocols etc. that meet those requirements. The testbed concludes with a public demonstration, and the prototype-derived specifications are taken forward.

11. Participants today – with you also from tomorrow? Canada, USA, UK, France, Australia, Sweden Use cases  display map, query one feature, return attributes in GeoSciML  query several map features, return GeoSciML file for download  reclassify map features based on GeoSciML GeologicAge or Lithology Activities: Testbed 2

20. A Boreholes section from the BGS logs near Dover across the Channel to the BRGM logs on the Calais coast

21. Results  Use-case 1: query feature  Query one map feature (e.g. a geologic unit) and return GeoSciML

22. Results  Use-case 2: download features  Download map features in view as GeoSciML

23. Results  Use-case 3: re-classify features  Use standard legend (symbols, terms) for rock types and ages

24. Activities: Testbed 2

25. Testbed2 use case 1

27. Testbed2 use case 2

30. Testbed2 use case 3

32. Significant Outcomes  GeoSciML adopted as national standard  Australia (federal and state geological surveys)  EU: being submitted to INSPIRE (EU Spatial Data Infrastructure)  BGS, BRGM, SGU already committed to its development  USGS and GSC committed to use this standard rather than NADM  GeoSciML Workshop / Session: GeoSciML 1.1 and Testbed 2  September 2006, Liege, BE, IAMG06  public forum for GeoSciML 1.1 and Testbed 2  special session at IAMG06

33. Next:  GeoSciML Task Group meeting: 5. Testbed 2 meeting  Sept 2006, Brussels, BE  make progress on GeoSciML 2.0  review GeoSciML 1.1

34.  GeoSciML  collaboration for standard geologic map data format  an application of international geospatial standards (ISO, OGC)  derived from NADM, XMML, and others  to be released as IUGS-CGI specification in 2006/7  international testbed is in progress  Web sites  CGI-DMC WG home http://www.bgs.ac.uk/cgi_web/tech_collaboration/data_model/data_model.html  CGI-DMC WG twiki https://www.seegrid.csiro.au/twiki/bin/view/CGIModel/ Summary
