The primary use is in the County Real Property Lister Department to assist in maintaining the real estate assessment and taxation database, and in determining approximate ownership boundaries and acreages; and tax parcel numbers. The map is also used to assist in identifying parcel boundary conflicts (gaps and overlaps) and in identifying parcels that are not listed in the database.
The County Land Records Department uses the map to assist in answering questions from the public about land ownership, and as a parcel data layer overlay for a variety of mapping and GIS products and services.
Other County departments such as Zoning, Forestry, and Register of Deeds are regular users of the map data.
Private users include land surveyors, assessors, real estate agents, and engineers.
The maps are for illustration purposes and may not be suitable for site-specific decision making. Information found within should not be used for making financial or other commitments. Bayfield County provides this information with the understanding that it is not guaranteed to be accurate, correct, current, or complete and conclusions drawn from such information are the responsibility of the user. While every reasonable effort has been made to ensure the accuracy, correctness, and timeliness of the maps, Bayfield County assumes no responsibility for errors or omissions. The foregoing warning is exclusive and in lieu of all other warranties of merchantability, fitness for particular purpose, and/or any other type whether expressed or implied. In no event shall Bayfield County become liable to users of these maps, or any other party, for any loss or direct, indirect, special, incidental, or consequential damages, including but not limited to time, money, or goodwill, arising from the use or modification of the maps.
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.
To assist Bayfield County in the maintenance of the Parcel Ownership Maps, users are encouraged to provide Bayfield County information concerning errors or discrepancies found in using the maps.
The parcel boundary layer purposely contains inaccuracies due to the sometimes inaccurate nature of the source documentation. These inaccuracies are addressed as time and budgets permit. The parcel GIS data layers are separately maintained and corrected to produce a correct and seamless county-wide parcel data layer.
In all cases, the best available data was utilized. Surveyed section data supplanted the digitized section data where available.
Certain PLSS monuments have been located to varying higher accuracy standards. These monuments are identified by symbols on the maps and the source documentation is included as attribute information.
Maps were compiled one for each Civil Division.
Section lines, roads and hydrography were digitized from USGS 7.5 minute series topographic maps. Civil Divisions mapped earlier during the mapping project were board digitized from paper maps. Civil Divisions mapped later were "heads-up" digitized from scanned DRG images.
Survey maps, Subdivisions, highway plats, etc. were drawn in discrete digital files using coordinate geometry and then inserted and fit to the base map. The fitting of each of these survey maps is described in accompanying text documents that may be obtained from the Point of Contact.
Forty lines were constructed using standard section breakdown techniques, supplemented by data from the original government surveys to depict fractional forties on the west and north boundaries of each PLSS Township
Using the Real Estate Assessment and Taxation database, parcel boundaries were drawn. When the description in the database was insufficient to map the parcel, deeds were obtained and the parcel boundaries mapped from the deed description. Metes and bounds descriptions were drawn using coordinate geometry.
Parcel identification number, legal description or deed reference, and acreage were annotated on the map for each parcel in the form of attributed AutoCAD block objects.
Parcel boundaries created in the initial mapping were duplicated on a separate layer (GIS_Par_Boundary) and edited to form a correct and complete polygon topology using simple lines, polylines and arcs, with nodes at each intersection.
Parcel identification numbers were extracted from the parcel ID blocks and placed as plain text on a GIS PIN layer (GIS_Par_Ident). Many PIN's created in the initial mapping are shown outside the parcel boundaries for readability on the hard copy output. In these cases the GIS PIN number was moved inside the parcel and scaled and/or rotated to fit within the parcel boundary.
A polygon topology was created in Autodesk Map using the GIS parcel boundaries as link objects and the GIS PIN numbers as centroids objects.
GIS PIN numbers were linked to the most recent Tax Assessment Database and to an internal Object Data Table containing the parcel ID number.
A GIS Polygon layer (GIS_Par_Poly) was created from the polygon topology, using Mpolygon objects, with links to the Tax Assessment database via the PIN. >From the data on this layer, ESRI compatible ArcInfo Coverage, Shape and Export (E00) digital files can be readily produced.
Maps for each Civil Division are updated and maintained on a regular schedule as listed in the Currentness_Reference section.
The updates include; Parcel splits and any errors discovered by the Real Property Lister Department. Newly filed survey maps, highway plats, PLSS retracements, and corrections provided by the Land Records Department. Revised links to the most recent Tax Assessment database. Alignment and registration of map features with aerial orthophotography. Newer and more accurate data is continually being integrated into the maps through the update and correction process.
Road Centerlines, Road Right-Of-Way, Road Names, Hydrography, Hydrography Names, Parcel Boundaries, Parcel Dimensions (where available), Parcel Polygons, Tax Parcel Identification Number, Parcel Area, Legal Description or Deed Reference, Section Lines, Major Power Lines, Major Pipelines, Government Lots.
This is not a true number, but rather a character attribute used to identify a parcel within the Tax Assessment database. The first three characters identify the Civil Division. The next six characters identify the parent parcel number. The last three characters identify parcel splits.
A common PIN was assigned to each of the following parcel catagories that had no corresponding PIN in the assessment database; lakes, surveyed roads, general unlisted parcels.
