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.

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.

• Exploring use of WaterML for probabilistic discharge forecasts within GEOWOW

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

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)

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

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

KISTERS Water SolutionsMichael 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

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

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”, 2012-16

• In support of GEO Water Task and Integrated Global Water Cycle Observations (IGWCO) Community of Practice

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

Time Series Metadata (differences)

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

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

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

Project Output: enabling Thematic Mapsof 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…?
