EuroFlood Index — Satellite-Derived Flood Depth Maps for Europe
A queryable, cloud-native spatial index over the JRC / Copernicus CEMS-EFAS Satellite-Derived Flood Depth Maps for Europe (Betterle & Salamon, 2025). It answers which historic floods hit a location, and when — across Europe, 2015–2024 — without downloading the depth rasters, so a tool can then fetch only the specific flood-depth GeoTIFFs it actually needs.
- Coverage: Europe · 2015–2024 · ~3,280 flood events · ~90 m grid
- License: CC-BY-4.0 (see Attribution below)
- Built with: the open-source
eurofloodPython library - Latest version:
v1.0.0/
Layout
Each release is an immutable vX.Y.Z/ prefix (so a library release always reads the exact
index it was built against):
Data model
The index is a sparse COG whose pixel values are combo_ids — each identifies the
set of flood events that inundated that ~90 m cell. flood_dictionary.parquet maps
combo_id → [flood_id, …], and events.parquet maps flood_id → {start_date, end_date, year, source download_url, …}. So "which floods hit this area?" is a spatial mask plus
two joins — no depth raster download required.
Use it
With the library (recommended):
Directly (any HTTP / S3 tool — public, no credentials):
Provenance & reproducibility
manifest.json pins the grid fingerprint, schema versions, and per-file SHA-256 checksums
for the release. You can rebuild the index yourself from the source maps with euroflood.
