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
Carbon sink
Biodiversity

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!

7. 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

8. 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)

9. Example: Satellite data availability for Camargue

10. 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!
