15 15 Geological Map Data How will the data delivered by OneGeology be organized and formatted ? 1.Image format : Raster images paper map scans 2.Vector Format: Geological units : polygons & attributes Faults : vectors/lines & attributes locations : points & attributes

16 16 Workshop Consultation Results What data/maps do workshop participants have ? Only paper maps available11% Raster data available52% Vector data available72% Fees charged for maps/data25% Vector data available online28% Raster data available online35% (accuracy +/- 15%)

19 19 Contents 1.Requirements analysis 2.Geological map data 3.Standards/Technology 4.Architectures 5.What are the challenges? 6.Summary S

20 20 Standards/Technology 1.The technology is available. standard-based, open vs. commercial 2.Standards are essential for understanding & interoperability 1.Geoscience standards: Age?, Lithology?, Stratigraphy? 2.Data model Conceptual Geology model 3.Exchange Formats: OGC, GML, GeoSciML? 4.Online access: WMS, WFS, WCS, etc. 5.Terminology : multiple languages? Formats, models, systems, projections, hardware, software, etc...?

21 21 Schematic interoperability means: This approach avoids the requirement to agree upon a single interpretation and legend and will allow delivery of geological coverage for any area of the world. However: OneGeology will likely contain national "boundary faults" caused by data not being harmonized. Data in a common data format and structure without harmonizing the content and interpretation between territories.

22 22 Contents 1.Requirements analysis 2.Geological map data 3.Standards/Technology 4.Architectures 5.What are the challenges? 6.Summary

23 23 Architectures Where will the data flow from the source to the user and how will it be managed ? Some Options : a) Distributed model b) Centralized model c) Hybrid model

24 24 Architecture Models: 3 parts OneGeology Data Delivery Geology Coverage Data Sources OneGeology Portal

25 25 Links and Translation S = standard OneGeology online data transfer/access OneGeology Portal Geology Coverage Data Sources OneGeology Data Access S Translation

26 26 OneGeology Portal Geology Coverage Data Sources OneGeology Data Access Translation S Access to participant data/maps

27 27 Access to Participant Data/Maps How nations provide OneGeology with access to their data will depend on the Architecture model selected. Options: a) Scan of paper map b) Raster map c) Vector map file (ESRI, Intergraph, etc.) d) GeoSciML file e) Online map service (WMS, WFS, etc. ) f ) ??????????????? (2) OneGeology Data Management (3) Geology Coverage Data Sources (1) OneGeology Data Access Translati on S

28 28 OneGeology Portal Geology Coverage Data Sources OneGeology Data Access Translation S Data Delivery to Users

29 29 Data Delivery to Users How will OneGeology deliver geological information to the world? Options: 1.A searchable on-line catalogue of geology maps/data with links to data/images? 2.Downloadable/viewable images of geology ? 3.Downloadable/viewable geology vector files ? 4.Web data services (WMS, WFS) using a standard format/structure ? (GeoSciML?) OneGeology Data Management Geology Coverage Data Sources OneGeology Data Access Translati on S

30 30 a) Distributed Architecture Model Participants manage their data locally and make it accessible online for delivery through the OneGeology Web Server USER WEB SERVER S S S S S

31 31 b) Centralized Architecture Model Participants submit their data for loading into a OneGeology Database which delivers it online through the OneGeology Web Server. USER 1G DATABASE delivery S S

32 32 c) Hybrid Architecture Model Data are managed either locally or in the OneGeology Database for delivery via the OneGeology Web Site. USER 1G DATABASE delivery S S WEB SERVER

33 33 Contents 1.Requirements analysis 2.Geological map data 3.Standards/Technology 4.Architectures 5.What are the challenges? 6.Summary

34 34 7) What are the technical challenges? What challenges must OneGeology address ? 1.Participants with a wide range of know-how and resources. 2.Integration of maps/data with very different format, content, and structure. 3.Delivering geological information that can be understood by non-specialists from highly technical data. 4.Establishment of dependable systems that deliver OneGeology data in real time.

35 35 Contents 1.Requirements analysis 2.Geological map data 3.Standards/Technology 4.Architectures 5.What are the challenges? 6.Summary

36 36 Summary Key points to remember ? The proposed OneGeology technical approach will: Accommodate the needs of all participants. Deliver structurally-consistent geological data online. NOT require scientific harmonization of geology. Place importance on the transfer of technology. Allow participants to provide access to their data in whatever form they have. Technology is available to meet OneGeology requirements.
