Example of a potential violation after a wildfire. Images in panel a (Credits: Google Earth Pro) show the land cover evolution of an area where a wildfire occurred in 2014 (highlighted polygon), from 2013 (before the fire) to 2019 (alleged violation). Graph in panel b shows the surface reflectance acquired from satellite averaged within the aforementioned polygon hit by a fire. In particular, panel b reports the reflectance derived from three Landsat-8 images: before the fire (7 June 2013, dashed line), after the fire but before the construction (29 June 2015, long dotted line), and, finally, after a building was constructed (24 June 2019, solid line).
