OGC/WMO Hydrology Domain Working
Group
What is the OGC?
• The Open Geospatial Consortium, Inc. (OGC) is a nonprofit, 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

History - Perspective
• 1969 – Internet “Invented”. Carl generates his first computer map .
Intergraph, LaserScan, and ESRI begin business.

• 1998 – First OpenGIS® Specification adopted.
• 1998 - Google Started Business
• 1999 – First OGC Web Mapping Test bed.
• 2000 – Web Map Service Interface Spec 1.0 approved

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.

Integral part of CI;
Requirement for CI sustainability and extensibility, esp. with 3rd party components
AND - CI efforts are also a way to inform standards development

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.dwg
• Twiki http://external.opengis.org/twiki_public/bin/view/HydrologyDWG

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

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

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

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

Water-Use Data System (cont.)

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
