They furnish units for mapping and provide uniformity of concepts and terms. Wetlands are defined by plants, soils and frequency of flooding. Generally, wetlands are lands whereby water saturation is the dominant factor determining the nature of soil development and the types of plant and animal communities living in the soil and on its surface. Five defined systems form the highest level of the classification hierarchy: Marine, Estuarine, Riverine, Lacustrine, and Palustrine. All but the Palustrine system are broken into subsystems in which classes are based on substrate material and flooding regime or on vegetative life form. Six classes are based on substrate and flooding regime: 1) Rock Bottom with a substrate of bedrock, boulders or stones; 2) Unconsolidated Bottom with a substrate of cobbles, gravel, sand, mud or organic material; 3) Rocky Shore with the same substrate as Rock Bottom; 4) Unconsolidated Shore with the same substrate as Unconsolidated Bottom; 5) Streambed with any of the substrates; and 6) Reef with a substrate composed of the living and dead remains of invertebrates (corals, mollusks or worms).NWIBAY polygons represent California Bay Area wetland ecosystems.See for descriptions: Cowardin, L.M., V.

Downloadable Data14.01614.016 Digitized from photos and maps at mixed scales (1:24,000 et al)2006060109070300Arc/Info 5.1UnknownThere are large numbers of small (ponds, etc.) polygons throughout the feature class. Sliver elimination is almost impossible to perform without significant "real" data loss. Great care must be taken in processing these feature classs. They push the capabilities of GIS systems. Attempts were made to subdivide large polygons. Occasionally more subdivision is required to prevent software failures. Some assignments seem strange at first glance, i.e., sewage treatment ponds show up as freshwater, diked ponds. A few (4-5) gross labeling errors were encountered and corrected as per knowledge of field biologists working in the area (1991).The attribute completeness seems to be good, considering the numbers of polygons.
