2 Abstract Groundwater Information Network Fed-prov-terr-int l collaboration to disseminate groundwater data online, through the use of international standards and leading geospatial methods. Brodaric GIN 06 Dec

3 Data heterogeneity in Canada Distributed and heterogeneous data syntactic, schematic, semantic heterogeneity in ON-QC wells Quebec rock type Ontario rock type Brodaric GIN 06 Dec

4 Solutions: central vs distributed Central Database GIN Hybrid Spatial Data Infrastructure Brodaric GIN 06 Dec

5 Levels of Interoperability pragmatic GW Practices (data usage) semantic GW Ontology (data content) schema syntax GWML, WaterML (data structure) GML (data language) Hydrology OGC system WFS, WMS, (data systems) Brodaric GIN 06 Dec

6 Architecture Data Portal data use GIN Portal NGWMN Portal GWML2 GeoSciML WaterML2 O&M GWML, WaterML2, Excel, PDF, Ascii, Data Pipeline data transfer WMS WFS SOS mediator Metadata Ontology Data translation Data integration Cache GML O&M GWML, WaterML2 Data data supply WMS WFS SOS Other NRCan AB ON NS USGS Brodaric GIN 06 Dec

7 Interoperability levels in action ON QC Lithology Sand Sand syntactic GWML <lithology> <name >Sand</name> </lithoogy> schematic semantic GIN simple lithology ontology Brodaric GIN 06 Dec

8 Interoperability levels in action: GWML2 standard structure standard content standard syntax Brodaric GIN 06 Dec

9 Schematic interoperability: standards GroundWaterML2 Brodaric GIN 06 Dec

10 Semantic interoperability: ontologies Global Ontology general concepts Upper-Level ontology (DOLCE amount-of-matter ) Domain ontology (GIN-GeoSciML lithology, public schema public vocabulary GIN-GeoSciML sand ) Application ontology (ON material1, ON sand ) Application ontology (QC matprim, QC SABL ) local schema local vocabulary sand clay soil SABL ARGL TERR Brodaric GIN 06 Dec

11 Pragmatic interoperability Web service profiles, best practices how to: use the services, serve data on the web E.g. SOS Profile for Hydrology, SDWBP Brodaric GIN 06 Dec

12 Problem: missing data links SDI SDI SDI SDI geonames.org LD LD LD ent-canada-weather-station/ atmospheric water gauges, Climate data ( surface water rivers, lakes, watersheds, Nat l Hydro Network ( surface water gauges, Nat l Hydrometric Network ( groundwater aquifers, wells, gauges GW Info Network ( Brodaric GIN 06 Dec

13 Groundwater Information Network National YK BC AB SK MB ON QC NS NL International USA, EU, AU Data Layers Usage Usage Statistics sessions: 44,119 users: 15,391 Return visitors: 66% GGP aquifer views: 483 GGP data downloads: 2404 P/T well views: 9,974 P/T well downloads: 1049 Other info requests: 22,822 Brodaric GIN 06 Dec

14 GW Interoperability: wells CAN: water wells (9 provinces) USA: water wells (USGS, 50+ states) Brodaric GIN 06 Dec

15 GW Interoperability: monitoring data CAN: groundwater level (5 provinces) USA: groundwater level & quality (USGS, 50+ states) Brodaric GIN 06 Dec

16 GW Interoperability: aquifers CAN: key aquifers (30) USA: principal aquifers (62) Brodaric GIN 06 Dec

17 Interoperability: other, national FGP (Federal Geospatial Platform) Open GOC Portal PIN (Permafrost Info Network - CCGP) surface water: hydrometric network coming soon Brodaric GIN 06 Dec

18 Applications: international global groundwater modeling global groundwater monitoring national water accounting interoperability: international coming soon Brodaric GIN 06 Dec

19 Final Thoughts Canadian national Groundwater Info Network is operational and thriving Spatial Data Infrastructure + Linked Data technologies and standards Toward a North American groundwater data network Brodaric GIN 06 Dec
