Multi-temporal ASAR wetland maps. PC1 (top, left), the binary forested wetland map (bottom, left), and the multi-class forested wetland hydroperiod map (top, right) over-laid with the NWI boundaries for palustrine, broad-leaved deciduous, forest with either seasonally (PFO1C — longer flooding duration) or temporarily (PFO1A — shorter duration) flooded wetlands and the boundaries of the Patuxent River. Both types of wetland polygons are shown alone at the bottom right along with the illustration legend. Areas with more flooding and higher amounts of soil moisture through time are displayed in red on the hydroperiod map and those with less flooding and lower levels of soil moisture are displayed in cream.
