This dataset is an index of Public Land Survey System (PLSS) Townships, Ranges, and Sections containing the City and County of Denver.

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.

trs displays the smallest unit in the Public Land Survey System; Township/Ranges are subdivided into 36 Sections; each Section is approximately one square mile. The coverage format includes a tr (Township) region subclass.

This layer has been adjusted to Section corner data from the GIS parcel Section AutoCAD drawings. It also includes the half Township South of 12S14E Sections 31-34, designated as 12F14E (field TR).

Known Errors/Qualifications: The Canoa Land Grant area is not part of the Public Land Survey System. The trs layer includes sections in the Canoa Land Grant area as if it had been included in the survey.

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

The PLSS is the basis for Federal land ownership. This data includes township, range, section (first Division), and Intersected.

There are four layers loaded that are scale dependant with scale dependant labels. At the smallest scales, the state boundaries appear, as the user zooms in Townships and then Section then PLSS Intersected boundaries appears.

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.

PLS Township. In the Public Land Survey System a Township refers to a unit of land, that is nominally six miles on a side, usually containing 36 sections, some of which are designed to correct for the convergence of meridians or range lines, with boundaries conforming to meridians and parallels within established limits.WA Public Land Survey Townships MetadataClick for downloadService URL: https://fortress.wa.gov/dnr/arcgisext/weba_ext_prod4/rest/services/Cadastre/WADNR_Cadastre_OpenData/MapServer/8

However, the PLSS acts today as the structure around which all legal descriptions of land parcels in Minnesota are based. It is, therefore, an important framework for most geographic investigations that require information about land ownership. PLSS information is intended to be used for regional studies conducted at the county or multi-county level. The section lines are not meant to be used as legal records.

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. The PLSS First Division is commonly the section. This is the first set of divisions for a PLSS Township.; abstract: This data represents the GIS Version of the Public Land Survey System including both rectangular and non-rectangular survey data.

Summary This feature class documents the fire history on CMR from 1964 - present. This is 1 of 2 feature classes, a polygon and a point. This data has a variety of different origins which leads to differing quality of data. Within the polygon feature class, this contains perimeters that were mapped using a GPS, hand digitized, on-screen digitized, and buffered circles to the estimated acreage. These 2 files should be kept together. Within the point feature class, fires with only a location of latitude/longitude, UTM coordinate, TRS and no estimated acreage were mapped using a point location. GPS started being used in 1992 when the technology became available. Records from FMIS (Fire Management Information System) were reviewed and compared to refuge records. Polygon data in FMIS only occurs from 2012 to current and many acreage estimates did not match. This dataset includes ALL fires no matter the size.

Started compiling fire history of CMR in 2007. This has been a 10 year process.FMIS doesn't include fires polygons that are less than 10 acres. This dataset has been sent to FMIS for FMIS records to be updated with correct information. The spreadsheet contains 10-15 records without spatial information and weren't included in either feature class. Fire information from 1964 - 1980 came from records Larry Eichhorn, BLM, provided to CMR staff. Mike Granger, CMR Fire Management Officer, tracked fires on an 11x17 legal pad and all this information was brought into Excel and ArcGIS. Frequently, other information about the fires were missing which made it difficult to back track and fill in missing data. Time was spent verifiying locations that were occasionally recorded incorrectly (DMS vs DD) and converting TRS into Lat/Long and/or UTM. CMR is divided into 2 different UTM zones, zone 12 and zone 13. This occasionally caused errors in projecting. Naming conventions caused confusion. Fires are frequently names by location and there are several "Soda Creek", "Rock Creek", etc fires. Fire numbers were occasionally missing or incorrect. Fires on BLM were included if they were "Assists". Also, fires on satellite refuges and the district were also included. Acreages from GIS were compared to FMIS acres. Please see documentation in ServCat (URL) to see how these were handled.
