 Parcel Mapping Background

The primary goal of the Bayfield County parcel ownership mapping initiative is to graphically display the ownership of all real property in the county. Maps are compiled from property descriptions contained in source documents of record such as deeds, plats of survey, certified survey maps, DOT highway maps, and so on. Ancillary information is also gathered from sources such as orthophotography or 7.5 minute USGS topographic quadrangle maps. In all cases, the best available data was used. Maps were created using coordinate geometry and computer assisted drafting. 

Parcels are generally depicted at one of three scales: (1) One inch = 400 Feet (1:4800 Scale) for Section Maps, (2) One Inch = 200 Feet (1:2400 Scale) for Quarter-Section Maps, and (3) One Inch = 100 Feet (1:1200 Scale) for Subdivision Maps. All maps are referenced to the Bayfield County Coordinate System, cast on the Wisconsin HARN datum. Map units are the U.S. Survey Foot.

It must be emphasized that, although significant care has been exercised to produce maps that satisfy mapping accuracy standards, these maps are only as accurate as the source data from which they were complied. These maps are intended to be advisory and are NOT designed or intended to be used as a substitute for an accurate field survey, as performed by a registered land surveyor, to determine precise property location.
