1 GeoSciML 2.0: Significant changes and additions to the CGI-IUGS geoscience data model Bruce Simons

2 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 Co-Authors

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 Traditional Paper 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 Doesnt allow data exchange Single legend Requires further explanation

6 Digital Maps

7 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 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

14 What is GeoSciML? machine readable GeoScience Markup Language a Geological Data Model based on real world concepts that 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

15 The map sheet Map polygons and lines, described by GML geometries Geologic description (map legend) MappedFeature – geologic map elements
