7 CUAHSI – Consortium of Universities for Advancement of Hydrologic Science Alva L. Couch, Rick P. Hooper CUAHSI Hydrologic Information System: A five-year project to create a data discovery platform for water data –A catalog of water data time series (HIS Central). –A standard for water data publication (WaterML). Community-moderated controlled vocabularies for time series metadata, including: –Measured variables, units, sample medium, etc. –An ontology of concepts, together with a novel ontologically-driven data discovery client.

8 CUAHSI goals for GEOSS and AIP-6: Long term: CUAHSI catalog in GEOSS format. Short term (AIP-6): Factor CUAHSI catalog into separate reusable subsystems for: –Publication and discovery –Controlled vocabulary curation, reusability, and internationalization. Enable federated CUAHSI catalogs in Italy, South Korea, and New Zealand.

11 Joint Research Centre (JRC) Institute for Environment and Sustainability Peter Salamon, Milan Kalas JRC Climate Risk Management Unit within the Institute for Environment and Sustainability – focus on observation, evaluation, anticipation and communication of impacts of weather extremes and future climate change Development of the Global Flood Awareness System (GloFAS) initiated in 2011, to study WaterML-based architecture and web services support

12 European Centre for Mid-range Weather Forecasting (ECMWF) Florian Pappenberger, Fredrik Wetterhall Carries out scientific and technical research for development and operation of global models and data-assimilation systems for the Earth system, and for improving quality of weather forecasts Will provide test data of the TIGGE archive and a combination of the ECMWF land surface scheme HTessel and CamaFlood (a river routing algorithm) Exploring use of WaterML for probabilistic discharge forecasts within GEOWOW

13 Italian National Institute for Environmental Protection and Research (ISPRA) Martina Bussettini, Michele Munafò Environmental research institute and national environmental agency to coordinate federation of regional systems Has recently implemented WaterML service-based architecture to federate, standardize and publish hydrological time series Will host a hydro-catalog of all Italian Regions, in which one can search and find water data in a standard format

14 Regional Agency for Environmental Protection in Emilia-Romagna (ARPA ER) Silvano Pecora, Bordini Fabio Gives technical support to regional, district and local authorities on environmental policy Hydro-Meteo-Climate Service (SIMC) is a thematic operational node of ARPA ER; implementing WaterML- based architecture for real-time flood and other water management modeling for European Flood Awareness System (EFAS)

15 New Zealand National Institute for Water and Atmospheric Research (NIWA) Jochen Schmidt, Brent Wood Manages about 20% of New Zealand water monitoring stations; coordinates NZ regional water agencies Hosting OGC WMS, WFS, CSW, SOS services and WaterML time series data

16 Horizons Regional Council (HRC) of New Zealand Jeff Watson, Sean Hodges Regional water agency Plans to implement WaterML-based architecture for time series data and services Interested to use NASA LDAS to define severity and spatial variability of current drought conditions

17 KISTERS Water Solutions Michael Natschke, Stefan Fuest Provides environmental data management solutions in many countries, and helped develop WaterML 2 WISKI and Hydstra products used to collect, process and disseminate hydrological information Interoperability Server KIWIS serves hydrological data and derived data products from various sources through WaterOneFlow/WaterML1, SOS1/O&M and SOS2/WaterML2 Will contribute to the architectural design and infrastructure of GEOSS Water Services, and offer their professional server and service components KiTSM and KIWIS

18 the PYXIS innovation, Inc. Perry Peterson, Idan Shatz Software company that develops geospatial-intelligence technologies Provides WorldView client application based on use of an optimized hexagonal discrete global grid (DGG); this will be used for analysis and modeling of hydrologic processes on disparate data discovered through GEOSS resources and populated into the DGG Directly accesses GEOSS registries via CSW; supports OGC WMS, WFS, WCS, SOS, WPS

19 AIP-6 GEOSS Water Services Purpose: Provide additional operational, federated water information resources in GEOSS Scope: A global registry of water data, map and modeling services catalogued using the standards and procedures of the OGC and the WMO In collaboration with WMO CHy Theme 2 “Data Operations and Management”, In support of GEO Water Task and Integrated Global Water Cycle Observations (IGWCO) Community of Practice

20 AIP-6 GEOSS Water Services Application Services –Community info services, for serving: Observation Services –Water time series Model Services –Computed water time series Map Services –Web maps, geoprocessing Based on OGC WaterML, WFS, WMS, SOS, CSW

25 Time Series Metadata (differences)

26 AIP-6 Thematic Goals – 1 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

27 AIP-6 Thematic Goals – 2 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

28 What is an Observation? r3 OGC WaterML 2.0 Standard, page 12

29 OGC Observation & Measurements Model Simply put, an Observation has: –Domain: Feature of Interest –Phenomenon: Observed Property of the feature type of interest –Procedure: appropriate for the Observed Property –Result: value appropriate for the Observed Property –Metadata And an Observation can be associated with other Observations

30 WaterML 2 is a Profile of OGC O&M

31 General characteristics of WaterML 2 1.Communicates the semantics of hydrological time series data. 2.An explicit time series model that supports encoding of information crucial to correct interpretation of time series, such as properties describing the nature of individual data values and their relationships. 3.A flexible exchange schema that can be re-used in a number of scenarios. Includes concepts to deal with common complexities in cross-system data exchange, such as multiple identifiers and names. 4.The schema is reusable across different transport technologies, including FTP, and a variety of web services etc. 5.Ability to extend through use of external schema and soft-typing. 6.Ability to capture information relating to the provenance of a time series (i.e. how the time series was created). Allows for interpretation of ‘data products’ such as statistical summaries.

32 AIP-6 Connections 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

33 Project Output: enabling Thematic Maps of water information anyone can find & use 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…?
