easysnowdata.hydro.basins.grdc_wmo#

easysnowdata.hydro.basins.grdc_wmo(aoi: Any = None, *, source: str | None = None, **kwargs: Any) → GeoDataFrame[source]#

The GRDC / WMO basins and sub-basins that intersect aoi.

The GRDC server answers HEAD with 400, which GDAL’s /vsicurl sends before any range read, so the archive is fetched once with a plain GET into the easysnowdata cache and read from there.

Parameters:

aoi – Any form easysnowdata.aoi.parse_aoi() accepts.
source – Only "grdc" today.
**kwargs – Passed to geopandas.read_file.

Returns:

geopandas.GeoDataFrame – Whole basins (not clipped to the AOI), in EPSG:4326.
