Main Class (>50% Wetland) - GLWD v2
This file contains the global grids, assembled by combining all 33 wetland grids. This file shows the dominant wetland class within pixel, only for pixels where the total wetland extent exceeds 50% (in cases of ties, the lower wetland class is chosen); value 0 indicates inland pixels where dryland (non-wetland) dominates.
