GIS and remote sensing (RS) techniques using Landsat ETM+ objectoriented segmentation were developed to identify depressional isolated wetlands in a >2,600 km2 mixed land use area of north-central Florida, USA. Both the standalone RS method combined GIS/RS successful at identifying > 0.20 ha. Combining methods yielded producer user accuracies ranging from 93 100% 86 95%, respectively. The utilized successfully mapped could be used address questions surrounding national estimates areal distribution wetlands.
