Wetlands will be classified primarily based on the presence of water, therefore temporary water areas will become an essential part of Wetlands products. Wetlands include the following landscape types: Wetlands associated to permanent water bodies Wetlands not associated to permanent water bodies Wetlands with vegetation (macrophyte) cover or without Peatlands (having presence of surface water) Coastal wetlands (salt marshes, salines, intertidal flats) Wetlands include the following e.g. plant communities: Helophytes, Nimfeides (Nymphoides),Pleustophytes, Draft Michael Bock, table compiled on base of the GUIDELINES FOR VERIFICATION OF HIGH-RESOLUTION LAYERS PRODUCED UNDER GMES/COPERNICUS INITIAL OPERATIONS (GIO) LAND MONITORING , Draft 4
