Burnt Area Detection
Provided by 
The application produces the perimeter of a burnt area after a wildfire, from a pair of Sentinel-2 images acquired before and after the event. The result is a vector layer ready for damage assessment and restoration planning.
The indicator is dNBR, the difference in the normalised burn ratio derived from the near-infrared and short-wave infrared bands — the most reliable spectral signature of charred vegetation. What sets it apart is the double pass: dNBR is computed both on the native Sentinel-2 pair and on the super-resolved pair, and the final perimeter is the intersection of the two. The two resolutions validate each other, cutting the false positives a single threshold would produce.
The perimeter is then cleaned of isolated fragments and smoothed before export.
