1. Making Geological Map Data for the Earth Accessible OneGeology: assisting Geological Surveys worldwide to interoperate seamlessly on the Next Generation Internet Lesley Wyborn Simon Cox Robert Woodcock Australia

2. Making Geological Map Data for the Earth Accessible 193 years from this…………………to this 18152008

3. Making Geological Map Data for the Earth Accessible Geological Map Publishing 1815 - 2008 Time Lines –I815 first paper geological map –~1990 digital cartography –1994 web mapping emerges –2005 first interoperability test bed Most geological data exchange has been based on local data bases which were designed to support cartography Proprietary Formats No standards, so difficult to merge data sets from different agencies

4. Making Geological Map Data for the Earth Accessible OneGeology is more than a digital map….. Data conform to generic ISO/OGC standards (GML, WMS and WFS) Uses GeoSciML: a standard information exchange model and encoding for geoscience data Each Geological Survey maps from their private schema to the standard Each Geological Survey keeps its own internal data structures OneGeology is not just about maps (WMS): it is moving to unlock the data behind the maps (WFS)

5. Making Geological Map Data for the Earth Accessible What Geological Surveys need to be aware of OneGeology Level 1 requires ISO compliant metadata and basic information infrastructure OneGeology Level 2 requires a more mature information infrastructure with –Master Data Management plans –Data product specifications (eg ISO 19131) –A formal governance structure including vocabularies Demands of WFS can expose limitations in existing information systems

6. Making Geological Map Data for the Earth Accessible OneGeology: opportunities arising Geological data are in a single standardised format from any OneGeology participant Standardised data reduces the barrier to data integration Standardised data encourages development of tools for analysis and modelling applications Tools can be implemented as services: they do not need to be installed by each user

7. Making Geological Map Data for the Earth Accessible A Key Benefit of OneGeology Accessible data in standardised formats allows sensible, but ambitious software planning

8. Making Geological Map Data for the Earth Accessible 80+ Countries only need1 Portaland a few tools 2D map service 3D model service Fluid modelling service

9. Making Geological Map Data for the Earth Accessible Beyond Geological Maps …………. Earth System Science A wide range of multidisciplinary fields of research augment classical Earth Science today; geosphere-biosphere-cryosphere- atmosphere interactions are particularly important. The 33rd IGC programme highlights the need to promote interaction and integration of the Earth Sciences.

10. Making Geological Map Data for the Earth Accessible Interaction and Integration of Earth Science data Similar international initiatives to OneGeology in other domains –topographic, water, marine and climate domains –same technology framework as OneGeology GML, WMS, WFS, Catalog Services, etc –OneGeology will integrate with these domains Integration of Earth Science data with other scientific domains will enable transnational research to solve global issues such as climate change and sustainable resource utilisation

11. Making Geological Map Data for the Earth Accessible Summary OneGeology leads a major transition in data delivery for Geological Surveys The advantages are that –Geoscience data will be made more easily accessible –The latest versions of that data can be dynamically accessed –More tools available (some as services) to process these standardised data –We will be able to tackle transnational issues such as climate change and resource utilisation To take full advantage of Internet 2.0, data custodians must ensure their data can map to standards This will depend on good internal governance
