Why Standards?
• Accessibility• Versatility• Consistency• Ensure correct use• Remove ambiguity• Leverage toolkits
3
GEOSS Work plan
• DA-06-01 GEOSS Data Sharing Principles1. There will be full and open exchange of data, metadata,
and products shared within GEOSS, recognizing relevant international instruments and national policies and legislation;
2. All shared data, metadata, and products will be made available with minimum time delay and at minimum cost;
3. All shared data, metadata, and products being free of charge or no more than cost of reproduction will be encouraged for research and education.
• GEOSS Architecture Implementation Pilot– Proposed for future AIP
4
Hydrology DWG
• Hydrology Domain Working Group (HDWG)• Joint Working Group formed by the Open
Geospatial Consortium (OGC) and the World Meteorological Organization (WMO) Commission for Hydrology (CHy)
• Seeking technical and institutional solutions for describing and exchanging data describing the state and location of water resources.

Hydrology DWGhttp://external.opengis.org/twiki_public/HydrologyDWG/WebHome
• Developing WaterML 2.0 Candidate standard• Conducting OGC Interoperability Experiments
(IE) - demonstrate/validate standards and services– Groundwater IE (Completed 2010)– Surface Water IE (Completed 2010-2011)– Hydrologic Forecasting (Underway 2011-2012)– Future

WaterML 2.0
• WaterML 2.0 is a candidate Open Geospatial Consortium encoding standard for the representation of in-situ hydrological observations data. WaterML 2.0 is implemented as an application schema of the Geography Markup Language version 3.2.1 and makes use of the OGC Observations and Measurements (O&M) standard and the OMXML GML Application Schema.
8
WaterML 2.0, continued
• OGC WaterML 2.0 will support encoding of hydrological and hydrogeological observation data in a variety of exchange scenarios.
• Example areas of usage are: exchange of data for operational monitoring and forecasting programs; supporting operation of infrastructure (e.g. dams, supply systems); exchange of observational and forecast data for surface water and groundwater; release of data for public dissemination; enhancing disaster management through data exchange; and exchange in support of national reporting.
