  1. Some notes on CyberGIS in hydrology Ilya Zaslavsky Spatial Information Systems Lab San Diego Supercomputer Center UCSD TeraGridCyberGIS Workshop, February 2-3, 2010

  2. What is the CUAHSI HIS? UT-Austin, SDSC/UCSD, Utah State U, Idaho State U, Drexel U, U of So. Carolina PI: D. R. Maidment (UT-Austin) CUAHSI HIS: NSF support through 2012 (GEO) Partners: Academic: 11 NSF hydrologic observatories, CEO:P projects, LTER, CZO… Government: USGS, EPA, NCDC, NWS, state and local Commercial: Microsoft, ESRI, Kisters International: Australia, UK Standardization: OGC, WMO (Hydrology Domain WG); adopted by USGS, NCDC, Army Corps of Eng An online distributed system to support the sharing of hydrologic data from multiple repositories and databases via standard water data service protocols; software for data publication, discovery, access and integration.

  4. CUAHSI Water Data Services 47 services 15,000 variables 1.8 million sites 9 million series 4.3 billion data values Map Integrating NWIS, STORET, & Climatic Sites The largest water datacatalog in the world

  5. International Standardization of WaterML OGC/WMO Hydrology Domain Working Group http://external.opengis.org/twiki_public/bin/view/HydrologyDWG/WebHome Towards an agreed upon - feature model - observations model - semantics Expressed as WaterML 2.0 By organizing - Interoperability Experiments and pilots, standard design activities, webinars… First OGC/WMO HydroDWG workshop : at Ispra, Italy, March 15-18, 2010

  6. Why CyberGIS • Some critical CI issues we encountered • Efficient management of large volumes of distributed spatio-temporal data • Understanding and unifying data models across sub-domains of water • Development of data exchange standards • Community ontology management and curation • When one writes a CyberGIScience proposal for hydrology… • Intellectual merit: reconciling different notions of space and time in a field that describes water dynamics • Broad impact: spatial data integration at a scale where critical mass is achieved fast, which makes it beneficial to broader multidisciplinary group of stakeholders, and thus sustainable • Transformative: large distributed data interfaced with models, and coupled with provenance management  resulting in a different rate and quality of simulations, larger models, and better decision-making
