Iberia — Sentinel-1 flood detections

TeraGIS flood-intelligence platform · change-detection pipeline · pre-existing IP demonstration
Valencia DANA — Oct 2024
Blue: platform S-1 detection, 01-Nov 06:02 UTC (50.9 km²). Orange: CEMS observed inundation for THIS event near peak (30–31 Oct optical/VHR, 542 km²) — water drained fast: 199 km² (L8, 30-Oct) → 85 km² (S1/S2, 31-Oct) → our pass. Crimson: CEMS 03-Nov monitoring (78 km²) — the time-matched benchmark: POD 0.46 · CSI 0.38 · FAR 0.30; vs near-peak extent FAR 0.009 (99% of our pixels inside the observed flood).
Ebro — April 2018 (CEMS EMSR279)
S1A 13-Apr-2018 17:55 UTC — the same acquisition CEMS used for its Zaragoza delineation (Tudela: COSMO-SkyMed, same evening). The orange benchmark here is time-matched by construction — zero timing gap — hence the direct score: CSI 0.30 · POD 0.33 · FAR 0.23 vs the EU reference (3 m CSK-derived); fluvial-corridor scoped (≤3 km of the river network), 2-ha minimum mapping unit.
