classification of wetlands, with an emphasis on the use of Geoegraphic Information Systems (GIS) which are predominant, in comparison to when mapping standards were first created. The new standard is also dedigned to be more conpatible with datasets from other government agencies, including the National Hydrography Dataset (NHD) and NOAA datasets.
