The original historic plat maps for Wisconsin were created between 1832 and 1866. In most cases, the UW Digital Collections Center does not record a specific creation date for the original maps. However, the collection also contains maps which correct previous editions. These more modern maps typically have a specific date or year defined.

This data set provides a means of identifying an x-y coordinate for the approximate center (centroid) of landnet units based on the corresponding standardized PLSS description (e.g., for PLSS Section this is DTRS -- Direction, Township, Range, and Section codes). This process is sometimes referred to as "protraction". The Landnet centroid shapefile includes coordinates in WTM83/91 and latitude/longitude expressed as decimal degrees or degrees, minutes and seconds.

description: This data represents the GIS Version of the Public Land Survey System including both rectangular and non-rectangular survey data. The rectangular survey data are a reference system for land tenure based upon meridian, township/range, section, section subdivision and government lots. The non-rectangular survey data represent surveys that were largely performed to protect and/or convey title on specific parcels of land such as mineral surveys and tracts. The data are largely complete in reference to the rectangular survey data at the level of first division. However, the data varies in terms of granularity of its spatial representation as well as its content below the first division. Therefore, depending upon the data source and steward, accurate subdivision of the rectangular data may not be available below the first division and the non-rectangular minerals surveys may not be present. At times, the complexity of surveys rendered the collection of data cost prohibitive such as in areas characterized by numerous, overlapping mineral surveys. In these situations, the data were often not abstracted or were only partially abstracted and incorporated into the data set. These PLSS data were compiled from a broad spectrum or sources including federal, county, and private survey records such as field notes and plats as well as map sources such as USGS 7 minute quadrangles. The metadata in each data set describes the production methods for the data content. This data is optimized for data publication and sharing rather than for specific "production" or operation and maintenance. A complete PLSS data set includes the following: PLSS Townships, First Divisions and Second Divisions (the hierarchical break down of the PLSS Rectangular surveys) PLSS Special surveys (non-rectangular components of the PLSS) Meandered Water, Corners, Metadata at a Glance (which identified last revised date and data steward) and Conflicted Areas (known areas of gaps or overlaps or inconsistencies). The Entity-Attribute section of this metadata describes these components in greater detail. This is a graphic representation of the data stewards based on PLSS Townships in PLSS areas. In non-PLSS areas the metadata at a glance is based on a data steward defined polygons such as a city or county or other units. The identification of the data steward is a general indication of the agency that will be responsible for updates and providing the authoritative data sources. In other implementations this may have been termed the alternate source, meaning alternate to the BLM. But in the shared environment of the NSDI the data steward for an area is the primary coordinator or agency responsible for making updates or causing updates to be made.

Tax parcel map of Waupaca County, Wisconsin. The layer was derived from a variety of source maps including: mylar county parcel maps, plats of surveys, deed descriptions, subdivision maps, certified survey maps, highway right-of-way plats, and township highway right-of-way maps. These source materials were of several different scales and were from dates ranging from the early 1850's to the present. This map provides a useful representation of the geometry and topology of tax parcels and is suitable for its intended purpose. It is not, however, meant to be used for the determination of land ownership or to be in any way a substitute for the land ownership and interest descriptions contained in individual deeds. The tax parcel layer is available in a county-wide or individual layer for each township, city, or village.

The municipalities data set (also known as civil divisions) delineates the incorporated cities, villages, and towns in Manitowoc County, Wisconsin. A variety of sources at several different scales and dates were used to map the boundaries including legal descriptions, annexation documents, surveys, and subdivision plats.

This data set was collected to provide wetland information for use in county, city, village, and town planning activities in the respective counties and for regional planning activities in Southeastern Wisconsin. This was clipped from a data set that consists of digital map files containing point and polygon features of wetland information covering Kenosha, Milwaukee, Ozaukee, Racine, Walworth, Washington, and Waukesha Counties. The files were compiled by the Southeastern Wisconsin Regional Planning Commission on behalf of the Wisconsin Department of Natural Resources as part of a cooperative agreement to update the Wisconsin Wetland Inventory in Southeastern Wisconsin. Each file covers one U.S. Public Land Survey System survey township, for a total of 82 files in the data set. The survey township files have also been merged into files covering entire counties. The digital map files were compiled with reference to one-inch-equals-100-feet-scale and one-inch-equals-200-feet-scale orthophotography acquired in the Spring of 2010, and also with reference to land use, vegetation, topographic, and soils information.

The Pre-European Settlement Vegetation Database of Wisconsin is a tabular database containing vegetative information extracted from the US General Land Office's Public Lands Survey original surveyors' notes for Wisconsin. The survey was conducted by private surveyors under contract to the General Land Office for the purpose of subdividing unsettled US lands for sale. Land was first surveyed into townships of 36 square miles, which where subsequently subdivided into 36 sections, each 1 square mile. Survey posts were set at the corner of each section (section corners) and at the midpoint between section corners (quarter section corners), resulting in a regular array of corners at half mile intervals along a 1 square mile grid. Additional survey posts were set when the survey line intersected navigable bodies of water at places called meander corners. Between 2 and 4 bearing trees were identified near each section, quarter section, and meander corner and recorded in the surveyors' notebooks, along with the presence of individual trees located along the survey lines between corners and the nature of the ecosystems through which the survey traversed.

We systematically went through microfilms and scanned ditigal images of the surveyors' notebooks and extracted vegetative information about the bearing trees, ecosystems, and disturbances recorded therein. This information was entered into a tabular database. Many trees were ambiguous noted only to genus level (e.g., birch, maple, pine). We used statistical methods to assign species to most of these trees (birch, oak, pine, maple, ash in northern Wisconsin, pine in southern Wisconsin). More information on this methodology can be found in Mladenoff, D.J., S.E. Dahir, E.V. Nordheim, L.A. Schulte, G.G. Guntenspergen. 2002. Narrowing historical uncertainty: Probabilistic classification of ambiguously identified tree species in historical forest survey data. Ecosystems 5, 539-553. Additionally maples and birches in southern Wisconsin were subjectively classified to species level based on location and associated species.
