Surface Water Interoperability Experiment

Update 17 February 2010

An experiment planning document is underway, with the latest draft attached to the twiki below.

Note that the plan is to meet at the ISPRA Hydro-DWG planning meeting on either 15/3 or 18/3. Can you please contact me peter.fitch@csiroNOSPAM-PLEASE.au to indicate if you are planning to attend and on which of those days best suits you.

Agenda for ISPRA SurfaceWater? IE Experiment 15 or 18 of March

• Introductions
• Main aims of IE
• Presentation of plans so far
• Individual organisation aims
• Define process for finalising planning
• Next meeting

Background

There has been considerable interest in developing up additional Interoperability Experiments as part of the DWG. Reminding members of the policies and procedures of an IE which can be found in OGC document 05-130r3. Summarising briefly, IE's must:

• Focus on an interoperability issue relevant to the OGC and the DWG
• Be completed in a reasonable timeframe ~4-6 months
• Share the results with all members of the OGC
• Participants shall not be paid for contribution (i.e. the contributions are all in kind)

Further, IE's are open to OGC members of good standing, but non-OGC observers may be included on a case by case basis.

Linkage to Groundwater IE

Please review the ground water IE to ensure that you are aware of the technological focus for that IE. This will guide you on what and how you might want to contribute. We also need to ensure that the IE is complementary to the GW IE.

Timetable

• Call for expressions of interest 15 December 2009
• Collation of expressions 31 January 2010
• Circulation of possible IE for comment TBA

List of interested parties and ideas.

Please add your ideas and contributions by editing the table below.

Organisation	Ideas for IE	Possible contribution to IE	Contact
CSIRO	TBA	Contribution to the development of WaterML2? suitable for surface water
IOW - Sandre	Ideally doing cross-border quality/quantity data interchange with countries sharing a common river (ex : Rhin - Rhein - between Germany & France but other situations can, of course, suit as well). Going further it could be interesting to exchange information on the same event/period (eg: flood, high rainfall, tracking a specific pollution); I'm sure this will lead to unexpected observations	we can provide the real datasets (maybe not for all the quality aspects : this should be further refined), "remodeled" datasets, thematic/technical expertise, data servers/storage/bandwidth
52° North	-	We can contribute a SOS implementation supporting WaterML? 2.0; through this SOS implementation we will be able to make water level data for the German Federal waterways (e.g. for the Rhine) available (this data would be provided by the Federal Waterways Engineering and Research Institute)
Federal Waterways Engineering and Research Institute	catchment orientated approach of water monitoring and management, test catchment Rhine basin using cross-border data from Switzerland, France, Germany and the Netherlands	providing data of the German federal hydrometric network (quantity and quality) over WISKI system (Kisters); supplying SOS implementation of system PEGELONLINE (WaterML? 2.0 adaptation by 52°North)
CUAHSI	Cross US/Mexico border experiment with water quantity data	TBA
KISTERS	Check feasibility of service definitions in distributed server landscape of all participants	Consume and provide services

Possible Scenario

The scenario for the surface water IE is looking likely to be a cross-border one. There is interest in the US for a US/Mexico experiment, and also in Europe exchanging data across borders which share a common river. In this case the IE will initially focus on surface water data availability. Given the broad interest in this IE, it is also likely that the IE will not focus on one geographical area, rather it will have a couple (More likely 2, one in the US and one in Europe) , representing the areas of interest to the participants. For each study area, it important to have both contributing parties involved in the i.e. For example, if the study area is the Rhin-Rhein, participants from both Germany and France will be required.

Phases of the Surface Water IE.

This section details some ideas on phasing of the IE into a series of experiments leading up to a testbed in which the data services will be put to work in some way. The current IE planning at this stage is only for phase one.

Phase 1

This phase will concentrate on data availability, with participants standing up data services and contributing to the development of WaterML2? . Contributions of clients suitable for visualising surface water data are also required.

Phase 2

This phase could concentrate on service discovery, and or standing up basic processing hydrological processing services, perhaps a simple water balance model.

Phase 3

Testbed
