GEOGloWS ECMWF Streamflow Hydroviewer
Description
The global HydroViewer is where the global streamflow network can be viewed in its entirety. Streamflow data, including forecasts and historical data, can be viewed by interacting with the displayed spatial data.
The HydroViewer provides an interactive map interface for:
- Viewing animated streamflow forecast maps provided by an ESRI Dynamic Mapping Service from the Living Atlas;
- Retrieving streamflow data for particular river segments via the Streamflow REST API hosted by ECMWF;
- Performing post-processing streamflow calibration using measured discharge including integration with selected national discharge gauge networks.
Provides a utility for creating hydroviewers for subsets of the global model:
- Clip global model shapefiles to extents of:
- Boundaries drawn on a map
- A shapefile or geojson of boundaries
- Predefined country or world region borders (ESRI Living Atlas)
- Export clipped shapefiles:
- To a specified geoserver
- As a zip archive
- As a Hydroshare resource (requires log in to tethys via hydroshare)
- Export the fully functioning hydroviewer as an HTML file.
