Web Services IG Report

• Support CWIC development and implementation with the goals:

• To establish CWIC as a Web service• With the development of what would hopefully become a “standard”

interface for inventory search, results and granule-level data access• Eventually to evolve to replace CWIC with member agencies employing

the “standard” interface directly to their inventory and data systems

• At WGISS #30, explore the possibility of merging the Web Services Interest Group into the WADC Project to encourage and promote focus on CWIC and the development of a “standard” set of Web Services interfaces supporting inventory search, ordering and granule-level access.

WGISS

Grid IG• Participants: CNES, NSAU, CAS• Projects: • WAG (Wide Area Grid) – Initiated by CNES• Ukrainian-Chinese Grid System for Flood Monitoring • Upcoming activities • Further extending of core architecture within Ukr-Chi joint

project, in particular- certificate support- providing possibilities for transparent cluster usage- MODIS archive visibility within system- automatic queries redirection on both sides

WGISS

Grid IG input to CEOS Deliverables• Grid IG supports activities for the following CEOS Deliverables

6. Health applications6.1.Flood and Disease Sensor Web for Monitoring and Early Warning8. Disaster Management8.1. Caribbean Flood Pilot and Namibia Flooding Demonstrations toinclude directory of available tools, datasets, and methodologies8.2. WGISS can develop a procedure for how agencies can respondquickly to natural disaster events with imagery provision. GlobalResource Information Database (GRID), web service, sensor web, andother technologies will be applied for efficient/rapid production andmapping of satellite data and maps for disaster response within 24-48hours.

• Technology contributions to DI-06-09: Use of Satellites for Risk Management for GEO & GEO DI-09-02b_3 (Namibian Flood Monitoring)

WGISS Sensor Web IG • Supports GEOSS task AR-09-02: Interoperable Systems for GEOSS

c) Sensor Web Enablement for In-Situ Observing Network Facilitation (POC: Terence van Zyl)

• Technical issues associated with the exploitation of the OGC Sensor Web Enablement (SWE) Standards are also being investigated (Wyn Cudlip)

• Proof of concept is provided for using Sensor Web for tasking and acquiring data from satellites, and Grids for workflow management and data processing – Technology contributions to DI-06-09: Use of Satellites for Risk

Management for GEO DI-09-02b_2 (Caribbean Flood Monitoring) & GEO DI-09-02b_3 (Namibian Flood Monitoring)

WGISS Sensor Web IG Inputs to Disaster Management

• Namibian Flood Sensor Web Project– Objective: to integrate remote sensing into a flood and water-

related disease modeling, monitoring, and early warning and decision support system

– Current activity is to submit a proposal for sustaining support to the World Bank June 2010. Components:• WP 1 – Management, coordination, dissemination (MAWF, UN-SPIDER)• WP 2 – Capacity Building, End-user interaction (UNW-DPC, UN-SPIDER)• WP 3 – Flood Sensor Web (NASA lead)• WP 31 – Flood mapping services (NASA/NOAA, USRI, UN-SPIDER, DLR)• WP 32 – Flood forecasting services and hydrological modeling (NASA/NOAA, USRI)• WP 4 – Water-related disease (e.g. malaria) spread modeling (NASA/NOAA, USRI)• WP 5 – Hazard Monitoring and Mitigation System (DLR lead)• WP 51 – Spatial Data Management (DLR)• WP 52 – Multi-Risk Assessment (floods, health/diseases) (DLR, USRI)• WP 53 – Decision Support System (DLR)

WADC Summary• Participants from NOAA, NASA, USGS, UK Space,

JAXA, CEODE/CAS (China)• Open invitation to other agenciesActivities:• Results of GCI testing:– Identified need for middleware providing a single

point of search and access for satellite data– Identified a need to promote the number of and the

visibility of community portals that tailor access to data and services needed by specific user communities

WGISS

WADC Summary (cont)• CEOS WGISS Integrated Catalog (CWIC) Prototype

initiated– CWIC will support the GEO supported catalog

interface OGC CSW 2.0.2 ISO profile to communicate with GEO and community portals

– CWIC will distribute directory searches to the IDN– CWIC will distribute inventory searches to the CWIC

partner agency systems using native protocols– CWIC will implement the WGISS Search Criteria v1.0– CWIC will implement the WGISS Domain Information

Model– 1st demo expected in December 2010

WGISS

WADC Summary (cont)• WGISS Search Criteria for inventory search is being developed

with inputs and review by multiple WGISS agencies• WGISS Domain Information Model that defines the

information model for satellite data for search and access is being developed.

• Participation in the GEO Task 09-01b (Data, Metadata, and Products Harmonization) task. WGISS inputs to harmonization will include WADC outputs such as WGISS Search Criteria v1.0 and the WGISS Domain Information Model.

• Need to promote WGISS recommendations to the appropriate GEO committees and tasks by all the WGISS reps.
