Allerte di deforestazione in tempo quasi reale del sistema UMD GLAD (Global Land Analysis and Discovery), distribuite tramite Resource Watch (WRI). Il layer segnala eventi recenti di disturbo forestale rilevati su immagini Landsat, classificati per livello di confidenza (1 = basso, 2 = medio, 3 = alto) a risoluzione 30 m, così da individuare potenziali perdite di copertura arborea poco dopo che si verificano.
The layer reads the UMD GLAD near-real-time deforestation alerts from the Google Earth Engine ImageCollection projects/resource-watch-gee/for_003_nrt_rw1_glad_deforestation_alerts. GLAD (Global Land Analysis and Discovery, University of Maryland) detects forest-disturbance events from Landsat time series and publishes them as alerts distributed through Resource Watch (WRI).
system:time_start in descending order and taking the first element.b1 is selected and clipped to the polygon of interest.Metadata reports the alert date, the maximum alert value found in the area, and the mean confidence over the polygon.
