Questo layer mappa l'estensione e la tipologia delle zone umide e dei corpi idrici interni, evidenziando aree di grande valore per la biodiversita e serbatoi di carbonio come laghi, bacini, fiumi, paludi d'acqua dolce, foreste allagate, zone umide costiere e salmastre e torbiere (bog, fen e mire). Deriva dal dataset globale delle zone umide di Resource Watch (wat_039), una classificazione basata su GLWD-3 con 11 classi, a risoluzione di circa 30 m. Ogni colore identifica una classe distinta di zona umida; le aree non umide sono mostrate trasparenti.
The layer shows the distribution of wetlands and inland water bodies, a categorical (discrete) classification with 11 wetland types derived from the GLWD-3 scheme: (1) lakes, (2) reservoirs, (3) rivers, (4) freshwater marsh and floodplain, (5) swamp and flooded forest, (6) coastal wetland, (7) pan/brackish/saline wetland, (8) bog, fen and mire (peatland), (9) intermittent wetland/lake, (10) 50-100% wetland, and (11) 25-50% wetland. These classes identify biodiversity hotspots and carbon sinks.

Method: The single band of the Google Earth Engine asset projects/resource-watch-gee/wat_039_rw0_wetlands is clipped to the area of interest and resampled to a 30 m grid. The categorical values are rendered with an 11-colour palette; nodata and non-wetland pixels are masked as transparent. For large areas the image is split into quadrants, downloaded in parallel and merged with a nearest-neighbour, maximum-value algorithm.
