Get HydroBASINS level 07 catchment (via Ramsar WFS)
Queries the Ramsar Sites Information Service (RSIS) WFS for a single HydroBASINS (HydroSHEDS) level 07 catchment by HYBAS_ID, fixes invalid geometries, reprojects to EPSG:3035, and looks up the list of EU countries that catchment overlaps from a fixed catchment-to-country mapping (R function 'get_hydrobasinsL7_catchment'). Only catchments with at least some EU territory are available; no bulk dataset download is required, only the requested catchment is fetched live from the WFS.

| Id | Title | Data Type | Description |
|---|---|---|---|
| catchment_id | Catchment ID | string | The HydroBASINS level 07 HYBAS_ID to retrieve (10-digit Pfafstetter-based identifier, e.g. 2070104700). Must be one of the known level 07 catchment IDs with at least some EU territory; catchments entirely outside the EU are not available. |
| Id | Title | Description |
|---|---|---|
| catchment | Catchment geometry | The retrieved HydroBASINS level 07 catchment boundary (MULTIPOLYGON), reprojected to EPSG:3035, saved as a GeoPackage. |
| countries | Countries for catchment | The list of EU country codes that the requested catchment overlaps, looked up from a fixed catchment-to-country mapping. Non-EU countries the catchment may also overlap are excluded. |
