Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Water Area is a spatial representation of polygonal hydrography features (Stream/River over 8 feet wide, Lake/Pond, Canal/Ditch, Swamp/Marsh). This polygon feature class was originally derived from a line coverage that was stereo-compiled as part of the Oakland County Spring 2000 digital orthophotography project. </SPAN><SPAN>The data was updated on February, 2023, per ad hoc request. Key attributes include the ReachCode and the GNISID as defined in the National Hydrography Dataset (NHD). Previously called Waterbody. Note: Null Field values mean the Data is not Available or Not Researched.</SPAN></P></DIV></DIV></DIV>
Description: The NationalWetlandsInventory digital data files are records of wetlands location and classification as defined by the U.S. Fish & Wildlife Service. This polygon feature class was adjusted from a shapefile downloaded in 2001 from the State of Michigan's Online Geographic Data Library (http://www.mcgi.state.mi.us/mgdl/). The feature class was reprojected from its original projection, and some of the atttributes were removed. The original data was published from 1979-1994, and was collected at the same scale as the USGS 7.5 minute topographic quadrangle maps. The key attributes include: ACRES, NWICODE, SYSTEM, CLASS, WATER, and SUBCLASS.
