JRC European flood hazard — available datasets#

The jrc-flood backend ships a single curated product (the EFHM) — there is no dataset= to choose. The request axis is the return period, selected with return_periods=.

Product Band Return periods (years) Native resolution Units CRS Licence
JRC European Flood Hazard Map (EFHM) water_depth 10, 20, 30, 40, 50, 75, 100, 200, 500 ~90 m (3 arc-second) metres EPSG:4326 CC-BY-4.0

A return period may be given as an int (100), a string ("100"), or an RP-prefixed string ("RP100"). The default when return_periods= is omitted is [100].

Listing the product programmatically#

from earthlens.jrc_flood import Catalog

catalog = Catalog()
list(catalog.datasets)              # ['efhm']
row = catalog.get("efhm")
row.band                            # 'water_depth'
row.return_periods                  # [10, 20, 30, 40, 50, 75, 100, 200, 500]
catalog.license_id                  # 'CC-BY-4.0'

Coverage & packaging#

  • Europe and the Mediterranean Basin — one whole-Europe GeoTIFF per return period (Europe_RP{n}_filled_depth.tif) on the JRC CEMS-EFAS open-data server.
  • The backend reads only the AOI window over /vsicurl, so a small subset never downloads the full per-return-period file (~300 MB compressed on the wire; ~23 GB uncompressed at 110162×51992 px).
  • Global JRC flood hazard (JRC/CEMS_GLOFAS/FloodHazard/v2_1, ~90 m, also covering Europe) is available via the gee backend.
