1 OGC/WMO Hydrology Domain Working Group

2 Helping the World to Communicate Geographically What is the OGC? The Open Geospatial Consortium, Inc. (OGC) is a non- profit, international voluntary consensus standards organization that is leading the development of standards for geospatial and location based services. –The OGC facilitates a consensus process in which government, private industry, NGOs, and academia collaborate to create open and extensible software application programming interfaces for geospatial and other mainstream information technologies

3 Helping the World to Communicate Geographically History - Perspective 1969 – Internet “Invented”. Carl generates his first computer map. Intergraph, LaserScan, and ESRI begin business – Invented First Web Mapping Application (Xerox) 1994 – OpenGIS Consortium Founded 1994 – Netscape formed 1996 – XML Developed Started – Mapquest comes on-line – First OpenGIS® Specification adopted Google Started Business 1999 – First OGC Web Mapping Test bed – Web Map Service Interface Spec 1.0 approved 2005 – (June) Google Earth Launched (July) MS Virtual Earth Launched 2007 – The “Neogeography” term coined

4 Helping the World to Communicate Geographically Benefits of open standards Prevents a single group from controlling a standard Facilitates competition Stimulates innovation Customers benefit from not being locked into a particular supplier. Source: Open Standards, Open Source, and Open Innovation: Harnessing the Benefits of Openness, April Committee For Economic Development. Integral part of CI; Requirement for CI sustainability and extensibility, esp. with 3 rd party components AND - CI efforts are also a way to inform standards development

5 Helping the World to Communicate Geographically Hydrology 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 Public mailing list https://lists.opengeospatial.org/mailman/listinfo/hydro.dwghttps://lists.opengeospatial.org/mailman/listinfo/hydro.dwg Twiki

6 Helping the World to Communicate Geographically © 2009 Open Geospatial Consortium, Inc. 6 Expected 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

7 Helping the World to Communicate Geographically Development Focus Plan Do Demonstrate Improve Hydro-DWG workplan priority Develop IE Complete IE Conclude IE Demonstration Feedback to standards and services Observation Model Feature Model Vocabularies Services stack Iterative Development Thanks to Peter Fitch for this slide

8 Helping the World to Communicate Geographically HDWG Agenda, Silver Spring Meeting, June Introduction, results of Ispra (co-chairs), IEs and WaterML –8-8:20: David Lemon, HydroDWG planning and next steps –8:20-9:40: WaterML 2 and Harmonization Report updates (Pete Taylor and the WaterML 2 design group) –9:40-9:50 Groundwater IE update (Nate Booth); Surface Water IE announcement and kick-off invitation (Peter Fitch) 2. Presentations –10-10:25: Mark Nardi (USGS) - Water use data management at USGS: information model, implementations, prospects of water use science. –10:24-10:45: Roland Viger and Nate Booth (USGS) - Using existing and emerging OGC standards to support hydrologic models. –10:45-11:05: Ben Domenico (UNIDATA) - Managing point time series in netCDF/DAP –11:05-11:30: John Halquist (NOAA), Peter Gijsbers (Deltares) - Operational hydrologic forecasts and infrastructure operation: use cases and requirements; -- Pedro Restrepo (NOAA) - Interagency Water Resources Science and Services Initiative –11:30-11:45: Michael Piasecki (Drexel University), Ilya Zaslavsky (SDSC) - CUAHSI Hydrologic parameter ontology 3. Discussion and motions

9 Helping the World to Communicate Geographically Expectations Getting WaterML 2 into standardization pipeline (and defining what this pipeline should be) Assessing how complete the Harmonization report is, and engaging more participants Expansions of WaterML testing, within the resources we can align: –Hydrologic forecasting –Water use –Water quality and ontology work –The services stack, and recommended WaterML 2 transition –Standardizing hydrologic catalog interfaces –Alignment with MetOcean work © 2010 Open Geospatial Consortium, Inc. 9

10 Helping the World to Communicate Geographically © 2010 Open Geospatial Consortium, Inc. 10 Actions Move WaterML 2.0 to RFC package, form SWG, prepare to release for public comment and adoption Hydro DWG to discuss future scope of WaterML, given the started and planned IEs –Groundwater IE (ongoing) –Surface water (kicked off 6/16) – Peter Fitch will present People to register interest in joining the RFC submission Discussion between IE’s on service implementations –Develop ‘best practice’ / plan of attack to reduce redundancy of work –Sharing of implementations –Develop ‘best practice’ path for WaterML 2 adoption

11 Components of an Ideal Water-Use Database System 1.Conveyance-based data storage in a relational database relational data meet a predetermined level of completeness and quality 2.Incorporates differing geometries for partitioning of water quantities points of use, distribution/collection areas, land applications, etc. 3.Ontology for handling naming variations 4.Detailed associations of Sites with hydrologic Resource features

12 Components of an Ideal Water-Use Data System (cont.) 6.Store related Quantities that result from the use of water Acres irrigated, kilowatts generated, population served 7.Ability to incorporate or associate with Regulatory and Permit data 8.Blue Water/Green Water Components 9.Spatial (GIS) Component & Common Languages 10.What Else? Quantity Conveyed Acres Irrigated Bushels per Water Q Out of basin transfer

13 Other OGC Connections USGS ITIS: – Integrated Taxonomic Information Systems NASA Sensor web – Many water-related projects

14 Other activities Azure proposal Data carts, generating themes from HISCentral based on criteria HydroDesktop: unit tests, bug fixes, performance of services Support of Yoori’s work, for Irvine workshop HISCentral and the catalog: documented; mappings; optimization of services (indexes, stored procedures, etc.); rewritten harvester Installed iRODS, federated with Renci OLAP support of WEAP work at CUAHSI
