DRAFT

Scenario Development

• Discussion of scenario ideas, but not enough time to actually elaborate a complete scenario

• Show ability to integrate in situ & remote data– E.g., Precipitation -> stream gauge, soil moisture

• Show ability to create detailed spatial catalog of observation locations (points & bounding polygons)

• Potential Use Case types to address:– Flooding– Agricultural drought: WMS/WCS– Hydrology data: SOS & WaterML– Data & policy

Water SBA – key discussion points• Understanding components of the water cycle, in particular in low monitored areas

(=> IAHS PUB is working on that).– For that we need at minimum observations or models of: Precipitation, Evaporation, Soil moisture,

discharge.– Typically in-situ sensor obs are used. RS becomes more important.

• RS can assist in-situ observations (vice-versa)? Research required!! => bring together in-situ with RS is a goal.

• Standards for Geospatial / RS exchange ok (WxS).• Standards for timeseries / sensor exchange under development through OGC

HydroDWG (SOS/WaterML2).• GEO GCI should endorse and recommend OGC HydroDWG standards as domain

standards.• Bringing together in-situ obs and RS into a world water catalogue (water

community portal) will:– Help RS science as validation– Help science to find data– Help catchment managers (cross-national, cross-domain) to find data.

DRAFT

“GEO GlobalSensor DirectoryInfrastructure”

Vision: “World Water Catalogue”Where are all in-situ sensors in the world (water cycle)?

And related RS products?

Stations:Variables:PrecipitationEvaporationSoilFlow

Many Providers:Users: Find all stations.

DRAFT

Work Plan Development• Decide whether to establish Water WG

Yes. Chair: Matt Austin (NOAA). No co-chair: Stefan Fuest (KISTERS).• Engage w/GEO users stakeholders regarding requirements & problems the envisaged Catalogue will

assist: RS community, IAHS PUB , science community.• Engage with information providers:

NIWA, CUAHSI, BOM, USGS, GRDC, NOAA• Some possible Water SBA-specific milestones:

–GRDC data will be provided to Data-CORE through GeoWOW–UNEP-Live ability to publish & find using GEO broker–Using SOS & WaterML2. Adoption of SOS hydrology profile from OGC Hydrology DWG and GEOWOW.–Documentation/tutorials to help people use these services; Best-practice paper

• Cross collaboration ideas:–Standardized approach/profiles to SOS, WCS, WaterML2, vocabularies.–Show ability to integrate in situ & remote data–Precipitation -> stream gauge, soil moisture –How to unite in a scenario these projects that have different coverage area, time scale and spatial scales–Gap analysis – missing hydrological stations (e.g., in Namibia)–Partner w/Envirogrid on water flow & quality in Black Sea catchment area.

DRAFT

Unanswered Questions• How to unite in a scenario these projects that have different

coverage area, time scale and spatial scales?• Can AIP tell GEO that some standards should be more

recommended than others in particular areas?• What is relation (if any) between GEOSS AIP Water SBA and

OGC Hydrologic Information Sharing Pilot?• How does this initiative fits with World Water Online?

Presentations by participants• Speakers:

– Stuart Frye, SGT/NASA: Water & Flooding– Meixia Deng, GMU: Global Drought Mon. Syst.– Jochen Schmidt, NZ NIWA: Station Info. Mgmt. Syst.– Greg Giuliani, UNEP: UNEP-Live– Stefan Fuest, KISTERS: GeoWOW Hydrology

DRAFT

NIWA Briefing– Much data in New Zealand, cannot always find, access or

understand it– Heterogeneous methods & standards– Need: Catalog service, incl location info (Feature Svc)– Now have Geonetwork data catalog dc.niwa.co.nz– Station Info Mgmt Syst sims-wfs.niwa.co.nz

• Info about the stations, but not the data? Only stations, data next• Do they know about CUAHSI work in this area? yes

– Client: Env Info Browser ei.niwa.co.nz– Will offer use SOS & THREDDS for data access.

• Will use WaterML2 for SOS• Do they know about NOAA NODC CF/NetCDF templates?

– May use GBIF (for biodata) but work on SOS profile for biodata– Portal agnostic

13

DRAFT

WaterPedia – Stuart Frye• Working on baseline water-level mask• Want to use crowd-sourcing approach to get info.

– Will use OpenStreetMap approach– Include expert supervision

• Show excursions from normal during flood and drought• Start w/Landsat or other satellite data @ ~10m resolution• Regional pilots in southern Africa & Caribbean• Want to produce “WaterPedia”


noaa.gov

14

DRAFT

Global Drought Mon. Syst. – Meixia Deng• Need timely & accurate data on demand.• Most existing drought info systems not based on open stds or

compatible w/GEOSS. Coarse res, regional, maps only/no data.

• GMU wants to dev OWS system for drought monitoring: GADMFS = Global Agriculture Drought Monitoring & Forecasting System– Include data access, processing services, workflow services– Data sources: WCS, processing: WPS, result display: WMS

• Will use services registered in GEOSS CSR.

15

DRAFT

UNEP Live• UNEP: review & report on state of the environment.• UNEP-Live will be used to support this activity.• At interface between science and policy

– GET THIS SLIDE for plenary– Information-to-policy idea: ambitious scope, perhaps

• Assemble data, collaborate on reports, publish results.• Will discover and access content• Link to treaties and multilateral agreements• Prototype: http://www.uneplive.org • Can feed into EuroGEOSS broker, but not yet to discover new

content—will enhance in AIP-5• Targeting water security Use Case

16

DRAFT

GeoWOW Hydrology - Kisters• GEOWOW = GEOSS interoperability for Weather, Ocean & Water.• Kisters has software to collect data from sensors and make available via

OGC services.– Contrib s/w to Global Data Runoff Center.

• Some work packages already underway will be relevant to AIP-5 Water SBA.

• Working on improved discovery, access, processing & visualization services.– What do they mean by “improved”

• Heterogeneous sensors, software, formats. Much less standardized than weather data.– Participating in OGC Hydrology DWG

• GTN-R : near-real-time information• GRDC data will be provided to Data-CORE through GeoWOW• Using SOS & WaterML2. Establish hydrology profile for SOS.
