  1. GeoSciML: The logical data model of geological concepts Bruce Simons

  2. Co-Authors Eric Boisvert - GSC Boyan Brodaric - GSC Dominique Janjou - BRGM Christian Bellier - BRGM Simon Cox - CSIRO Yuichiro Fusejima - GSJ Bruce R. Johnson - USGS John L. Laxton - BGS Oliver Raymond - GA Steve Richard - AzGS

  3. Interoperability in the Geosciences “the ability of software and hardware on different machines from different vendors to share data” • Efficiencies for government • Efficiencies for industry • Benefits for the wider geoscience community

  4. Traditional paper map

  5. TraditionalPaper Maps • Advantages • Presents lots of information • Readily understood by experts (~0.2%) • Targeted to specific end-users • Disadvantages • Stand-alone product • Hard copy only • Allows only limited analysis • Doesn’t allow data exchange • Single legend • Requires further ‘explanation’

  6. Digital Maps

  7. Digital Maps • Advantages • Captures most map information • Human readable • Some data exchange capacity • Allows queries and analysis • Disadvantages • Targeted end-user • Single legend • ‘Flat’ data structure • Vendor specific format • No relationships, cross- sections, face notes

  8. Structured Digital Data

  9. Structured Digital Data • Advantages • Handles all the information • Is well-structured • Allows establishing data exchange standards • Caters for all end-users • Suitable for computer analysis • Machine readable • Disadvantages • Difficult for humans to read • Requires agreed standards

  10. IWG • Interoperability Working Group • International Union of Geological Sciences • Commission for the Management and Application of Geoscience Information • International Organization for Standardization • Open Geospatial Consortium Tony Cragg, Subcommittee, 1991

  15. What is GeoSciML? • machine readable GeoScience Markup Language • a Geological Data Model based on real world concepts • represents the complexity of geology • tells users what geological information goes where • developed by the international scientific community • builds on established standards such as GML • uses the ISO ‘feature’ model

  16. GML (Geography Markup Language) O&M (Observations & Measurements) GeoSciML (Geoscience Markup Language) XMML Boreholes Links to other Modelling Languages

  23. Testing the Standard • Testbed 12005 • A borehole demonstrator between UK and France • Testbed 22006 • Six nations delivering geological map data in GeoSciML • Testbed 32008 • Use Case 1 – Show a geological map from multiple sources • Use Case 2 – Return mapped features, sampled features and age and lithology vocabularies • Use Case 3 – User defined query • Use Case 4 – Data import to and export from client applications • Use Case 5 – Establish registry for web, vocabulary and symbology services
