1. Providing geoscience data globally OneGeology as an open geo(science) data model and the advantage of the distributed data system M KOMAC, T DUFFY, F ROBIDA, M HARRISON & L ALLISON July 2015

2. Providing geoscience data globally Background Initiated in 2007 by Geological Survey Organisations from around the globe: national and state / provincial / territorial Voluntary initiative (that became a formal structure in 2013) Global geoscience information infrastructure has raised the level of geological survey information delivery across the world

3. Providing geoscience data globally Achievements Mobilised well established international networks Implementing interoperability principles, metadata of maps and services Accommodating needs of geoscience data at various scales and various geological topics Has made geology a global leader in the field of SDI & an exemplar of a community working together Has spawned projects and initiatives across the world, some very large (i.e. continental initiatives such as OneG-E in Europe, GIN in USA and CCOP project in Asia)

4. Providing geoscience data globally OneGeology Consortium As of October 2013 OneGeology has become a Consortium with: a clear governance structure, formally defined rules, membership commitments, and with ambitious objectives.

5. Providing geoscience data globally OneGeology Consortium Currently there are 119 Members, 21 Principal Members, 2 Corporate Members (ESRI, Schlumberger) and 2 Associate Members Orgs (IUGS, GEM) 138 participating organisations Providing +300 data services from 70 surveys (and counting) Formally supported by UNESCO, IUGS, ICSU, GEO Officially recognised as being the global model for open geo-data sharing

6. Providing geoscience data globally OneGeology Governance Chair of the Board Board members (Africa, Asia, N America, S America, Eurasia, Europe, Oceania) Managing Director Finance & Secretariat [BGS] Operations [BRGM] OneGeology Board Consortium Members Principal Members with Voting rights Members (who have agreed to the Brighton Accord) Corporate Members Associate Members - Non-Geological Survey Organisations Operational groups Inc. 1). Technical Implementation Group 2). Technical Advisory Group External funding sources Science User Group

7. Providing geoscience data globally Objectives To be the provider of geoscience data globally To ensure an exchange of know-how and skills so all can participate Use of the global profile of OneGeology to increase awareness of the geosciences and their relevance (in contemporary society)

8. Providing geoscience data globally The system behind the name

9. Providing geoscience data globally …a distributed data system (no classical process of the data collecting & storing in centralised repository) …a distributed dynamic data system  serving the most up-to-date data …using a “buddy” service if a data provider lacks infrastructure or expertise/staff …an application of open global GeoInformation standards (WMS and WFS) to various topics  facilitating the inter-institutional / cross-border / global analyses & modelling OneGeology is…

10. Providing geoscience data globally Technical facts - 1 Based on interoperability principles using GeoSciML 3.2 (truly INSPIRE compliant) Maps on distributed servers & sent directly to web client after a submission of download demand Map/services data delivered via standard OGC web service (WMS / WFS) The list of metadata of maps / services is collected into a catalogue of services managed “centrally” Can display / aggregate all the maps Can display maps in different projections (polar regions)

11. Providing geoscience data globally Technical facts - 2 Public users can analyse OGC WFS & OGC SLD (Styled Layer Descriptor) querying of WFS’ Cookbooks, online help Buddy system – hosting and serving data for another participant that cannot do it itself & that have technical limitations Exporting data to different formats (i.e. KML, WMC)

12. Providing geoscience data globally INSPIRE list adopted OneGeology adopted the initial keyword dictionary list for specific topics of geoscience data List was taken from OneGeology-Europe project that developed the list compliant with the INSPIRE directive This will enable expanding services from serving purely geological data to serving the data from all geological (sub)disciplines A need to formalise the terminology related to geological/geoscience topics

13. Providing geoscience data globally The coverage Service providers Participants

14. Providing geoscience data globally OneGeology Portal: one-stop-info-service-point

15. Providing geoscience data globally Advanced functionality: use of SLD (Styled Layer Descriptor) to display the polygons presenting a required lithology or age : Thanks to a WFS-SLD query, only polygons which age is « Quaternary » are displayed (Example with Delaware US-DE DGS 100k Surficial Geology)

16. Providing geoscience data globally Advanced functionality: use of WFS to present statistics on polygons displayed -The WFS result (XML / GML) is analysed and transformed into statistics (Example with United Kingdom (GBR BGS 1:625k Bedrock Age))

17. Providing geoscience data globally Catalogue service (OGC CSW) – managed centrally All WMS and WFS services and layers (datasets) are instantly registered into geonetwork catalogue. The catalogue is then requested by the OneGeology portal thanks to a CSW request (XML response). Catalogue service registered in some intl. catals ( GEOSS).

18. Providing geoscience data globally Advantages of distributed data system! every data provider stays in control of its own data – on their servers (political issues) data is up-to-date (instantly)  higher data reliability system is more resilient to potential failures

19. Providing geoscience data globally Potential drawbacks of distributed data system! Failing connection(s) with data providers  datasets not available (solution is a backup in the cloud) Security (more vulnerable to hacking) System complexity (different data providers use different SW and HW) Standards (simple and clear cook-books guide data providers to prepare the data properly and in compliance with standards)

20. Providing geoscience data globally Which additional service could OneG include? Inclusion of scientific papers, reports, project results Inclusion of 3D geological data Inclusion of other geological thematic data Bring together & serve more data from geological archives from around the globe from various data providers/ collectors (geological maps, mineral occurrences, raw geoscience data, “hard to get“ & “archived“ data etc.) Integrate OGC data models between USGIN, CCOP, INSPIRE, AGG (Ground waterML, mineral resource occurrences – ERML) All georeferenced and interoperable!!!
