This data set represents a GIS Version of the Public Land Survey System (PLSS) including both rectangular and non-rectangular surveys. These are the cadastral reference features that provide the basis and framework for mapping. This feature data set contains PLSS and Other Survey System data. The other survey systems include subdivision plats and those types of survey reference systems. This PLSS dataset was compiled by IDWR in 2016/2017 showing Public Land Survey System (PLSS) data from a variety of sources, including BLM's CadNSDI, IDL's edits to the CadNSDI alongside alignments to data from a variety of counties. Source and Edit information are provided in the QQ layer.

An area defined by the Public Lands Survey System grid that is referenced by its tier and range numbers, and is normally a rectangle approximately 6 miles on a side with boundaries conforming to meridians and parallels. 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).

Public Land Survey System (PLSS) reference grid serves as base map information and may be used for planning and analytical purposes.Sections lines are approximate, except for those adjusted to verified section corners. Section lines adjusted to verified section corners as corners recovery sheets are received from registered surveyor.Converted from Intergraph to Graphic Data Systems (GDS) circa 1989, GDS to ESRI's SDE circa 1999. Section lines (polygons) periodically adjusted to reflect on-going section corner recovery. See Section Corners dataset for certified section and quarter corner locations, coordinates, recovery date and surveyor.

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.

9/2013: While this layer is maintained as a Shapefile, the coverage format is still required for certain nightly processing. See Steve Whitney. Lineage: The TRS layer for Pima County was extracted from a state-wide layer of PLSS Section boundaries as received from ALRIS. The ALRIS layer was tablet digitized from USGS 7.5 minute topographic quadrangle paper maps. In 1992, a database of Section corner locations was acquired from ADOT, and the TRS layer was adjusted to match those ADOT Section corners that were surveyed to an acceptable level. In 2010, the Section boundaries were adjusted to Section corner locations from the GIS parcel AutoCAD drawings.

BackgroundPLSS (from wikipedia)The Public Land Survey System (PLSS) is the surveying method used historically over the largest fraction of the United States to survey and spatially identify land parcels before designation of eventual ownership, particularly for rural, wild or undeveloped land. It is sometimes referred to as the rectangular survey system (although nonrectangular methods such as meandering can also be used).RanchosThe Spanish and, later, Mexican governments encouraged settlement of territory now known as California by the establishment of large land grants called ranchos, from which the English word ranch is derived. Land-grant titles (concessions) were government-issued, permanent, unencumbered property-ownership rights to land called ranchos.Why this dataset?This dataset was created in order to integrate the boundaries from two different datasets – a Rancho Boundary file from the Bureau of Land Management (BLM), and a parcel-accurate Township Range Section file created by the LA County Department of Public Works. There are many sources of this data out there, but the rancho are holes in the PLSS datasets and the TRS is a hole in the rancho files. This combines both of those.Method of conflationThese two datasets were combined, and any holes and overlaps were conflated to match the Rancho boundaries that were created by BLM.FieldsLABEL - Name of Rancho or TRSTOWNSHIP -Township NumberRANGE- Range NumberSECTION- Section NumberTYPE- IF this is a TRS or a RanchoMAP_LINK- Link to Rancho map

This polygon dataset is a compilation of all the townships in Snohomish County derived from the Public Land Survey System (PLSS) grid dataset. The PLSS grid is the master coverage of the PLSS maintained by the Assessor's Office. It contains linework and attribute information for townships and ranges. It is compiled from recorded surveys and plats, coordinates and linework supplied by private surveyors, Snohomish County Public Works Survey, cities, Washington State Department Of Natural Resources (DNR) and the United States Department of the Interior - Bureau of Land Management (BLM). Standard BLM methods are used to construct the aliquot grid. In coastal areas, the aliquot grid may not apply for many of the coastal sections, it has been constructed for the purposes of land title and defining map extents for automated routines.

Township and Range boundaries as defined by the US Public Land Survey System (PLSS). PLSS is a way of subdividing and describing land in the United States. Most lands in the public domain are subject to subdivision by this rectangular system of surveys, which is regulated by the U.S. Department of the Interior, Bureau of Land Management. Township and Range boundaries were generated from geodetic latitude and longitude coordinate pairs as recorded on BLM's official protraction diagrams of the state of Alaska. Most corners are protracted corners, calculated by the Bureau of Land Management in lieu of field or survey locations. In 2013 and 2015 the Matanuska-Susitna Borough shifted portions of this dataset to more accurately reflect the actual locations of section corners on the ground. These shifts occurred in the more populated areas of the Matanuska-Susitna Borough. Contact the MSB GIS division for more information.

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 ½ 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. The second division of the PLSS is quarter, quarter-quarter, sixteenth or government lot division of the PLSS. The second and third divisions are combined into this feature class as an intentional de-normalization of the PLSS hierarchical data. The polygons in this feature class represent the smallest division to the sixteenth that has been defined for the first division. For example In some cases sections have only been divided to the quarter. Divisions below the sixteenth are in the Special Survey or Parcel Feature Class. The second division of the PLSS is quarter, quarter-quarter, sixteenth or government lot division of the PLSS. The second and third divisions are combined into this feature class as an intentional de-normalization of the PLSS hierarchical data. The polygons in this feature class represent the smallest division to the sixteenth that has been defined for the first division. For example In some cases sections have only been divided to the quarter. Divisions below the sixteenth are in the Special Survey or Parcel Feature Class.

This dataset contains the boundaries of the Public Land Survey System (PLSS) Township Range Section boundaries, as well as the boundaries of the Ranchos and Landgrants that pre-dated the PLSS. In general these match the USGS topographic Quad Sheets from the US Geological Survey.

This dataset has been deprecated. Please use our 2017 Countywide Contours instead.These data comprise of one foot contours showing the elevation of Lake County, IL corresponding to the orthometric heights of the bare surface of the county (no buildings or vegetation cover). These data were developed from LIDAR data obtained between April 16, 2007 and May 07, 2007, and further supplemented by break lines collected from aerial photography taken at the same time. The contours and the aerial photography meet National Map Accuracy Standards for a 1 inch = 100 foot product. The contours have been created to be cartographically pleasing, as such some generalization has been introduced as expected. The contours have been tested against the original LIDAR points and conforms to the American Society for Photogrammetry and Remote Sensing (ASPRS) Specifications and Standards Committee, 1990, ASPRS Accuracy Standards for Large-Scale Maps, CLASS 1 map accuracy. The vertical datum is the North American Vertical Datum of 1988. The U.S. Army Corps of Engineers Engineering and Design Manual for Photogrammetric Production recommends that data intended for this usage scale be used for any of the following purposes: route location, preliminary alignment and design, preliminary project planning, hydraulic sections, rough earthwork estimates, or high-gradient terrain / low unit cost earthwork excavation estimates. The manual does not recommend that these data be used for final design, excavation and grading plans, earthwork computations for bid estimates or contract measurement and payment. Contour data is used by county agencies to study drainage issues such as flooding and erosion. Customers interested in the actual LiDAR data may download it at no cost from the USGS Center for LiDAR Information Coordination and Knowledge. These files are tiled by PLSS section and grouped by township and format for easier download. Please note that this dataset is available in for GIS in Esri shapefile format as well as for CAD in AutoCAD DWG and MicroStation DGN. We are unable to provide any support for CAD users beyond providing the data.

The TRS digital data set represents the Township, Range, and Section boundaries of the state. Beginning in the late 1840s, the federal government began surveying Minnesota as part of the Public Land Survey System (PLSS). The resulting network of land survey lines divided the state into townships, ranges, sections, quarter sections, quarter-quarter sections and government lots, and laid the groundwork for contemporary land ownership patterns.

The township, range and section boundaries were digitized at MnGeo (formerly known as the Land Management Information Center - LMIC) from stable base mylars of the U.S. Geological Survey (USGS) 30-minute latitude by 60-minute longitude map series (1:100,000-scale). All survey lines were extended across water bodies despite the fact that U.S. Geological Survey base maps depict them only on land. This addition allows all sections and townships to be represented as closed areas (polygons) ensuring that township and range location can be determined for any point in the state. It also means that the data set is not affected if lake levels change over time.

The section grid for all of urban Broward County. The Public Land Survey System (PLSS) is a way of subdividing and describing land in the United States. All lands in the public domain are subject to subdivision by this rectangular system of surveys, which is regulated by the U.S. Department of the Interior, Bureau of Land Management (BLM). The PLSS typically divides lands into 6-mile-square townships, which is the level of information included in the National Atlas. Each township is identified with a township and range designation. Township designations indicate the location north or south of the baseline, and range designations indicate the location east or west of the Principal Meridian. Sections are one-square-mile blocks of land, containing 640 acres, or approximately one thirt0sicth of a township. Due to the curvature of the Earth, sections may be slightly smaller than one square mile. Range refers to a vertical column of townships in the PLSS.
