Water-Quality Data Exchange

Data format based on USEPA Water Quality Exchange (WQX) (NWQMC WQ Data Elements)

Common definitions and semantics EPA’s Substance Registry System for chemicals Chemical groups Site types Sampling media Taxonomy

Common web services for serving Monitoring Locations and Water-Quality Results

Project Objectives

1) Common format and nomenclature

2) Web services to serve monitoring data

3) Services for users to find sites and data

4) Portal to merge disparate web service feeds

Future Work

Helping the World to CommunicateGeographically

Hydrology Domain Working GroupHydrology Domain Working Group

• A joint working group of the OGC and WMO constituted as an OGC Domain Working Group.

• Brings together interested parties to develop and promote the technology for greatly improving the way in which water information is described and shared.

• Co-chaired by representatives nominated by the OGC TC and the World Meteorological Organisation’s (WMO) Commission for Hydrology (CHy).

• Current Co-Chairs: Ilya Zaslavsky (SDSC), Ulrich Looser (GRDC) and David Lemon (CSIRO)

• > 50 Participants, > 30 Organisations

Expected OutcomesExpected Outcomes• An agreed feature model (ie. what are the features of the

hydrosphere (from an information perspective) and how are they related.)

• An agreed observation model. • Agreed vocabularies, endorsed by the community, and by

WMO in particular. Agreeing on semantics is a long process, but we should be able to recommend some vocabularies

• Also: services carrying the above

Groundwater Data Exchange – OGC/WMO HydroWG Interoperability Experiment

Test and enhance OGC standards for water observations

Exchange groundwater well characteristics and water levels with Canada

Next steps: streamflow, water-quality

National Groundwater Monitoring Network
