This dataset is part of the Cadastral National Spatial Data Infrastructure (CadNSDI) publication dataset for rectangular and non‐rectangular Public Land Survey System (PLSS) data.

This dataset represents the GIS Version of the Public Land Survey System including both rectangular and non-rectangular surveys. The primary source for the data is cadastral survey records housed by the BLM supplemented with local records and geographic control coordinates from states, counties as well as other federal agencies such as the USGS and USFS. The data has been converted from source documents to digital form and transferred into a GIS format that is compliant with FGDC Cadastral Data Content Standards and Guidelines for publication. This data is optimized for data publication and sharing rather than for specific "production" or operation and maintenance. This data set includes the following: PLSS Fully Intersected (all of the PLSS feature at the atomic or smallest polygon level), 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 and Conflicted Areas (known areas of gaps or overlaps between Townships or state boundaries). The Entity-‐ Attribute section of this metadata describes these components in greater detail.

The CadNSDI or the Cadastral Publication Data Standard is the cadastral data component of the NSDI. This is the publication guideline for cadastral data that is intended to provide a common format and structure and content for cadastral information that can be made available across jurisdictional boundaries, providing a consistent and uniform cadastral data to meet business need that includes connections to the source information from the data stewards. The data stewards determine which data are published and should be contacted for any questions on data content or for additional information. The cadastral publication data is data provided by cadastral data producers in a standard form on a regular basis.

Cadastral publication data has two primary components, land parcel data and cadastral reference data. It is important to recognize that the publication data are not the same as the operation and maintenance or production data. The production data is structured to optimize maintenance processes, is integrated with internal agency operations and contains much more detail than the publication data. The publication data is a subset of the more complete production data and is reformatted to meet a national standard so data can be integrated across jurisdictional boundaries and be presented in a consistent and standard form nationally.

This Quarter Section feature class depicts PLSS Second Divisions . PLSS townships are subdivided in a spatial hierarchy of first, second, and third division. These divisions are typically aliquot parts ranging in size from 640 acres to 160 to 40 acres, and subsequently all the way down to 2.5 acres. The data in this feature class was translated from the PLSSSecondDiv feature class in the original production data model, which defined the second division for a specific parcel of land. Metadata

In support of new permitting workflows associated with anticipated WellSTAR needs, the CalGEM GIS unit extended the existing BLM PLSS Township & Range grid to cover offshore areas with the 3-mile limit of California jurisdiction. The PLSS grid as currently used by CalGEM is a composite of a BLM download (the majority of the data), additions by the DPR, and polygons created by CalGEM to fill in missing areas (the Ranchos, and Offshore areas within the 3-mile limit of California jurisdiction).

The Missouri Public Land Survey System is a 1:24,000 scale geographic information systems (GIS) polygon layer based on the 7.5' United States Geological Survey (USGS) topographic maps. This data set has been extensively edited to improve the accuracy of the original product.

The Public Land Survey System (PLSS) is the way land in the United States is subdivided, it forms the foundation of Cook County's cadastral system for identifying and locating land records. Tax parcels are identified using township and section notation, in a modified format. The PLSS serves as a way for users to navigate the parcel geodatabase. This PLSS feature data set is intended to correspond to tax pages on the Cook County Tax Maps. They should not be used for measurement or surveyor purposes. In addition, the parcel attributes PINA (area/township) and PINSA (subarea/section) do not necessarily correspond to the PLSS township and section polygon in which a given parcel resides. The PLSS data is modeled as a single composite network coverage that encompasses townships (area), sections (subarea), quarter sections, and half quarter section. Tax map pages, which typically correspond to half quarter sections (in an east-west split), are modeled as a region subclass in the LANDFABRIC layer. If an indigenous people's reserve was present on the tax map, it was digitized to create subpolygons of the half-quarter section, and those polygons were attributed with the name of the reserve. Within this PLSS data set, a half-quarter section is the smallest polygon unit, except in cases where an Indigenous People's Reserve line is present. The cadastral data for Cook County have previously not been digital nor automated. This project is the initial automation for this information. This database was designed to represent a continuous, non-overlapping spatial database accounting for all land area in Cook County.The PLSS is updated as needed.

The field notes and plat maps of the public land survey of Wisconsin are a valuable resource for original land survey information, as well as for understanding Wisconsin's landscape history. The survey of Wisconsin was conducted between 1832 and 1866 by the federal General Land Office. This work established the township, range and section grid; the pattern upon which land ownership and land use is based. The survey records were transferred to the Wisconsin Board of Commissioners of Public Lands (BCPL) after the original survey was completed. Since that time, these records have been available for consultation at the BCPL's office in Madison, as hand-transcriptions, and more recently on microfilm. Now, they are being made available via the internet as electronic images. 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.

The National Flood Hazard Layer (NFHL) is a geospatial database that contains current effective flood hazard data. FEMA provides the flood hazard data to support the National Flood Insurance Program. You can use the information to better understand your level of flood risk and type of flooding. The simplest way for you to access the flood hazard data, including the NFHL, is through FEMAs Map Service Center (MSC).If you want to explore the current digital effective flood hazard data in a map, the best tool to use is the NFHL Viewer. From the NFHL Viewer, you may view, download, and print flood maps for your location.The NFHL is made from effective flood maps and Letters of Map Change (LOMC) delivered to communities. NFHL digital data covers over 90 percent of the U.S. population. New and revised data is being added continuously. If you need information for areas not covered by the NFHL data, there may be other FEMA Flood Hazard Products and Services which provide coverage for those areas.A list of the types of data available in the NFHL and information about other ways to access the NFHL may be found in the NFHL GIS Services User Guide.If you need more information about individual tables in the NFHL, the FIRM Database Technical Reference, found at FEMA’s Technical References, includes those details.For step-by-step instructions on how to read a flood map, you may view the How to Read a Flood Insurance Rate Map Tutorial.For more information, please visit the FEMA Flood Map Service Center.

These are the corners of the PLSS. This data set contains summary information about the coordinate location and reliability of corner coordinate information. The information in the corner feature has been collected by the identified data steward. For more information about corner locations, credits and use limitations the identified data steward in the corner feature should be contacted.

PLSSSections_GCDB is the second level of a hierarchical break down of the Public Land Survey System Rectangular surveys. This data is Version 2.0 2015 of the Utah GCDB. This data set represents the GIS Version of the Public Land Survey System. Updates are expected annually as horizontal control positions from published sources and global positioning system (GPS) observations are added. The primary source for the data is cadastral survey records housed by the BLM supplemented with local records and geographic control coordinates from states, counties as well as other federal agencies such as the USGS and USFS. This data was orginally published on 5/1/2015.The PLSS First Division is commonly the section. This is the first set of divisions for a PLSS Township, there are 36 Sections to the usual Township, measuring approximently 1 mile square. (640 Acres)

This dataset contains plans of operations for locatable mineral cases derived from Legal Land Descriptions (LLD) contained in the US Bureau of Land Management's, BLM, Mineral and Land Record System(MLRS) and geocoded (mapped) using the Public Land Survey System (PLSS) derived from the most accurate survey data available through BLM Cadastral Survey workforce. Geospatial representations might be missing for some cases that can not be geocoded using the MLRS algorithm. Locatable minerals include all minerals locatable under the 1872 General Mining Law. This data set contains cases for locatable minerals under plan level operations with the case disposition of 'Authorized' or 'Pending'.Each case is given a data quality score based on how well it mapped. These can be lumped into seven groups to provide a simplified way to understand the scores.Group 1: Direct PLSS Match. Scores “0”, “1”, “2”, “3” should all have a match to the PLSS data. There are slight differences, but the primary expectation is that these match the PLSS. Group 2: Calculated PLSS Match. Scores “4”, “4.1”, “5”, “6”, “7” and “8” were generated through a process of creating the geometry that is not a direct capture from the PLSS. They represent a best guess based on the underlining PLSS Group 3 – Mapped to Section. Score of “8.1”, “8.2”, “8.3”, “9” and “10” are mapped to the Section for various reasons (refer to log information in data quality field). Group 4- Combination of mapped and unmapped areas. Score of 15 represents a case that has some portions that would map and others that do not. Group 5 – No NLSDB Geometry, Only Attributes. Scores “11”, “12”, “20”, “21” and “22” do not have a match to the PLSS and no geometry is in the NLSDB, and only attributes exist in the data. Group 6 – Mapped to County. Scores of “25” map to the County.Group 7 – Improved Geometry. Scores of “100” are cases that have had their geometry edited by BLM staff using ArcGIS Pro or MLRS bulk upload tool.

6/12/13 - Errors in section attributes were corrected in the PLSS poly layer, primarily within the Sisseton Reservation area and along the Red River.This coverage represents the townships in the US Public Land Survey System for North Dakota. It is derived from the PLSS section layer compiled from ND Public Service Commission data by staff of the North Dakota Geological Survey in 1993.When my predecessors at the North Dakota Geological Survey left in 1993, they left little or no documentation as to how they compiled any of their GIS coverages. I took posession of their data early in 1994, and in my experience, this layer is a reasonable representation of the North Dakota PLSS. Bear in mind that it was developed at the 1:24,000 scale, which National Map Standards, (simply stated and generalizing to a certain extent) approximate a plus/minus 40ft accuracy. Having worked extensively with, maintained, and been the steward for this layer over the last 19 years, I know that it has a few areas that need some corrections, however, as a whole, it is a decent product. Currently, I plan to replace this layer with a GCDB based representation, but work on that will only progress once the GCDB is complete for North Dakota.- Rod Bassler, GIS Coordinator, North Dakota Department of Water Resources, formerly GIS Coordinator for the North Dakota Geological Survey

This layer is intended for use in the Wisconsin PFAS Interactive Data Viewer GIS mapping application, use for any other purpose should be done with caution to avoid misuse or misinterpretation of information contained in this layer. Please seek appropriate DNR staff support.PFAS results in Wisconsin DNR's Drinking Water System (DWS) Portal are presented on this layer. The results have been generalized by water system and are classified based on the levels of PFAS detected. Point locations are generalized to PLSS centroids and do not represent well or specific water supply system feature locations.Municipal Water System SamplingResults from municipal or public water supply systems that have sampled drinking water for PFAS. Sampling completed prior to 2022 may not be included on this map. More details about sampling results are on the Drinking Water System Portal.Map locations are shown at the Public Land Survey System section center point for each municipal water system rather than the exact location of the well.PFAS health advisory levels (HALs) and the hazard index (HI) approach are defined by the Wisconsin Department of Health Services (DHS).For more information contact the DNR Drinking and Groundwater Program.

Flathead County Cadastral Data ResourcesA snapshot of property and parcel data for June 2022.Department of Revenue Orion SQL property record database provided as both an SQL database and as tables in a file geodatabase.File Geodatabase and Shapefile options for parcel polygon GIS data.Visit the Montana State Library Cadastral MSDI page for more information on cadastral data and Orion property database : MSDI Cadastral (mt.gov)The Montana Cadastral Framework shows the taxable parcels and tax-exempt parcels for most of Montana. The parcels contain selected information such as owner names, property and owner addresses, assessed value, agricultural use, and tax district information that were copied from the Montana Department of Revenue's ORION tax appraisal database. The data are maintained by the MT Department of Revenue, except for Ravalli, Silver Bow, Missoula, Flathead and Yellowstone counties that are maintained by the individual counties. The Revenue and county data are integrated by Montana State Library staff. Each parcel contains an attribute called ParcelID (geocode) that is the parcel identifier. View a pdf map of the counties that were updated this month here: https://ftpgeoinfo.msl.mt.gov/Data/Spatial/MSDI/Cadastral/Parcels/Statewide/MonthlyCadastralUpdateMap.pdf The parcel boundaries were aligned to fit with the Bureau of Land Management Geographic Coordinate Database (GCDB) of public land survey coordinates. Parcels whose legal descriptions consisted of aliquot parts of the public land survey system were created from the GCDB coordinates by selecting and, when necessary, subdividing public land survey entities. Other parcels were digitized from paper maps and the data from each map were transformed to fit with the appropriate GCDB boundaries.
