  1. Use Case: The GEO-Wetlands Community Portal Jonas Eberle, Prof. Christiane Schmullius (University of Jena) Adrian Strauch (University of Bonn)

  2. Wetlands: Their value and their destruction Wetlands provide valuable ecosystem services • Approximately 64% of the wetlands have disappeared since 1900 • 40% have been lost in the past 40 years Transport Fishing Hunting Flood control Biodiversity Carbon sink

  3. SWOS User Requirements Workshop • User-friendly satellite data discovery and access • Availability search, downloading, pre-processing • Data catalogue & data broker • Include or reference to external data sources • News-line to inform users on new datasets • Simple visualization tools to easily explore available datasets • Map production assistance & demonstrator for service cases, best practices • Continuous updates of thematic products • Coordinate with other portals

  4. GEO-Wetlands Community Portal Objectives • Provide an overview of free available satellite data* • Simple access to pre-processed satellite time-series data* • Wetland-related models (e.g., derivation of geospatial products and indicators), pre-generated or on-demand • Provide a "knowledge hub" by collecting wetland-related data and information* • Make external databases available for map comparison and validation purposes* *Can be supported by GEOSS!

  5. Interaction with GCI • Using GEOSS portal widgets to search for external datasets • Requirements • Pre-defined queries (e.g., wetland area, data sources) • View metadata • Add layers to map • Provide same look&feel as on GEOSS (and maybe other community) portals

  6. How can GEOSS support the user requirements? • Search in external data sources (e.g., GBIF, ArcGIS Online) • Satellite data discovery (e.g., Landsat-8, Sentinel) • Coordinate with other portals But for end users we need to provide... • Simpler data formats (e.g., export search results as CSV, Shapefile; graphical overviews aggregated by time) • “Robust” and simple visualization tools (e.g., hide WMS link if server is down) • Further data exploration notes (e.g., what can users to with the data found in GEOSS)

  7. Example: Satellite data availability for Camargue

  8. Conclusions • Integration of GEOSS tools into portals is important • Extend our own datasets with external resources • Increase the visibility of GEOSS • Reusing GEOSS portal widgets saves much time • Need to focus on users requirements and needs of users • Simpler satellite data discovery and access • Map production assistance, tutorials, best practices, … Finally: Thanks to ESA for funding the widget development!
