Why Standards?

• Accessibility• Versatility• Consistency• Ensure correct use• Remove ambiguity• Leverage toolkits

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

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.

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.
