1. Provide a systematic way for publishing map services of water observations that index locations of accessible WaterML time series services.
2. Produce web services of the results of global models for flood and drought analysis , including:
– EC Global Flood Awareness System (GloFAS)
– NASA/NOAA Global Land Data Assimilation System for drought assessments
3. Link web services for observations and modeling , so observations can inform model calibration, and so models can furnish larger context for observations

4. Form federated national water data services for common variables
– Italy: ISPRA national, ARPA regional agencies
– New Zealand: NIWA national, HRC regional
5. Synthesize data, map, and modeling services to support specific useful applications, eg, linkage of watershed delineation with precipitation mapping over watershed + flow observations + model results at outlet
6. Advance the utilization of water services in developing countries , through access to global web services, and lightweight methods of publishing local data

• GEOSS Water Services can connect to
– Other Water SBA threads ( Esri , GLOS , MEDINA )
– Technical threads ( Esri , GEOWOW )
– Other related threads
( GeoViQua (Ag), FCU1 (DM), FCU2 (Ag) )
– Capacity Building, End-User focus

• Water data & model output providers follow consistent practices in applying the OGC O&M model and WaterML 2 standard
• This model description becomes part of the WMO Glossary of Terms
• GEOSS provides rules for publishing these maps
– Easy registration and quick, consistent discovery
How we’ll know we’re done :
• We can search GEOSS for time series of soil moisture, precipitation, stream flow and get a federated map of the results
• Other results…?
