This feature class represents a comprehensive, spatially referenced collection of zoning geometries as recognized by County Governments within the State of Wisconsin (the feature class is aggregated from county level data and represents zoning that is administered by the county). See the parcel project homepage for more detail on the parameters for how data was prepared and submitted to this project: http://www.sco.wisc.edu/parcels/submission/. Schema documentation can be found within this feature class as GIS metadata and here: http://www.sco.wisc.edu/parcels/data/assets/V3/V3_Wisconsin_Statewide_Parcels_Schema_Documentation.pdf#page=23.
