What SCOPE found
New water / flooding — 1.3 ha
1.9 km north-west · 52% sure

How sure is this?
The strongest area (#1) has 52% confidence. It appears in 3 of 6 later clear images, so it is not a one-day artefact. Radar could not confirm or rule them out (normal for vegetation changes), so the result rests on repeated clear optical views and the seasonal comparison. Only 0% of the area had clear optical views, so some change may be hidden by cloud. Note: Optical imagery was unusable (cloud); results rely on Sentinel-1 radar only. Confidence measures how strong the evidence for real surface change is; it does not identify the cause or who did it.
How it was measured
SCOPE used Sentinel-2 optical imagery at 10 m, cloud-masked and combined over each
period, Sentinel-1 radar as an independent check
.
The analysis took 2 seconds.
