Data offered docs-verified: Sentinel-1 GRD backscatter, pre- and post-event (VV, VH) · Sentinel-1 RTC backscatter, pre- and post-event (VV, VH) · Sentinel-2 L2A pre-event cloud-filtered composite (12 bands) · Copernicus GLO-30 DEM (resampled to 10 m) · 3-class flood labels (background, permanent water, flooded water) · Cloud and shadow mask (OmniCloudMask) · Binary CEMS flood delineation mask · Binary permanent-water mask · Binary validity mask
Coverage docs-verified: 65 countries (219 Copernicus EMS Rapid Mapping flood activations) · 2016-2026
Resolution docs-verified: 10 m (1024x1024 tiles on a common event-UTM grid)
Formats docs-verified: Cloud-Optimized GeoTIFF (inside uncompressed tar shards) · CSV (metadata inventories) · Parquet (tile_catalog)
Access docs-verified: Ungated public Hugging Face dataset; licence CC BY 4.0 for the compilation, splits and labels; dem layer under the Copernicus WorldDEM-30 licence

Use cases llm-inferred: Benchmarking or training flood extent segmentation from Sentinel-1 pre/post-event pairs · Fusing Sentinel-1, Sentinel-2 and DEM layers for early or mid-fusion flood mapping trials · Out-of-distribution testing of flood models on held-out EMSR857-871 activations · Checking flood delineation methods against manually validated labels for post-event mapping
Audience llm-inferred: GIS analysts · Remote sensing and earth observation specialists · Flood consultants and hydrologists working on flood mapping methods · Machine learning engineers building segmentation models

Constraints docs-verified: Full dataset is about 584-588 GB; selective download of layers and splits is needed for most uses · Peak disk usage is the size of your selection plus roughly --workers x 2 GB for the shards in flight · Dataset viewer is not available for the default config · dem layer carries a separate Copernicus WorldDEM-30 licence with its own notices · Held-out evaluation tiles are in a separate tree (geoid-flood-heldout)
