Originator Minnesota Land Management Information Center (LMIC)
Abstract 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 quarter-quarter section remains an important subdivision for rural Minnesota since these lines are used to define local boundaries, roads, and service areas.

The TRSQ digital data set represents the Township, Range, Section, Quarter section, and Quarter-quarter section divisions of the state. 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 ensuring that township and range location can be determined for any point in the state. It also means that the data is not affected if lake levels change over time.

The township, range and section boundaries were digitized at LMIC from the USGS 30' x 60' map series (1:100,000-scale). Quarter section and quarter-quarter section subdivisions were calculated using the section lines. They were not digitized from original plat book survey lines or from the meandered lines that surveyors laid out around water bodies. The existence of government lots within a quarter-quarter section is recorded in the data set; however, the government lot boundaries were not digitized. If a quarter-quarter section contains more than one government lot, the number of lots is recorded -- see Lineage, Section 2, for more detail.

Note: For most uses, TRSQ has been superseded by the Minnesota Department of Natural Resources' 1:24,000-scale 'Control Point Generated PLS' data set which is free online.

Title Public Land Survey System: Quarter-quarter sections (TRSQ), Minnesota
Abstract 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 quarter-quarter section remains an important subdivision for rural Minnesota since these lines are used to define local boundaries, roads, and service areas.

The TRSQ digital data set represents the Township, Range, Section, Quarter section, and Quarter-quarter section divisions of the state. 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 ensuring that township and range location can be determined for any point in the state. It also means that the data is not affected if lake levels change over time.

The township, range and section boundaries were digitized at LMIC from the USGS 30' x 60' map series (1:100,000-scale). Quarter section and quarter-quarter section subdivisions were calculated using the section lines. They were not digitized from original plat book survey lines or from the meandered lines that surveyors laid out around water bodies. The existence of government lots within a quarter-quarter section is recorded in the data set; however, the government lot boundaries were not digitized. If a quarter-quarter section contains more than one government lot, the number of lots is recorded -- see Lineage, Section 2, for more detail.

Note: For most uses, TRSQ has been superseded by the Minnesota Department of Natural Resources' 1:24,000-scale 'Control Point Generated PLS' data set which is free online. See http://deli.dnr.state.mn.us/metadata/pls_fortypy3.html for more information. Also, many county surveyors offices have more accurate PLS data sets.

Purpose The quarter-quarter section mapping base is a historical foundation for recording land ownership and management information. Since the early 1970s a variety of projects have been initiated to enhance the state's quarter-quarter section mapping base (40-acre units). Minnesota's earliest attempts led to the creation of quarter-quarter sections in a raster format with each cell representing a 40-acre area. In reality, quarter-quarter sections vary in area and shape and require more precise mapping. In the early 1990s, LMIC coordinated several client projects and organized financial cooperators to jointly develop the most accurate statewide, vector format, quarter-quarter section mapping base for general purpose use that existed at that date. This TRSQ information is intended to be used for regional studies conducted at the county or multi-county level. The lines in this data set are not meant to be used as legal records.

Associated Data Sets Note: The following Minnesota PLS data sets are all free online:

Quarter-quarter section level data set:

Control Point Generated PLS
This 1:24,000-scale data set was constructed using section corner coordinates from the Control Point Inventory as well as information from the original General Land Office surveyors' notes and plat maps. Note: the PLS quarter and quarter-quarter section lines do not cross meandered water bodies (the section and township lines do). See http://deli.dnr.state.mn.us/metadata/pls_fortypy3.html

Section level data sets:

1. Public Land Survey System: Sections (TRS), Minnesota
This 1:100,000-scale data set contains all PLS section and township boundaries as well as county boundaries for Minnesota. See http://www.lmic.state.mn.us/chouse/metadata/trs.html

2. Mn/DOT BaseMap
This 1:24,000-scale PLS township and section data does not include attributes, and sections are built as lines, not polygons. See http://www.dot.state.mn.us/tda/basemap/index.html

3. SECTIC-24K: Section Corner Database
SECTIC-24K is a digital file of the PLS section corners of Minnesota from the U.S. Geological Survey's 1:24,000-scale quadrangle maps. Also included are software utilities that: 1. provide user-specified section corner extraction from the SECTIC-24K database by county, quadrangle or township, 2. convert among PLSS, UTM and latitude/longitude coordinates, and between NAD27 and NAD83 datum values, and 3. create user-defined output files in dBASE format. See: http://www.lmic.state.mn.us/chouse/metadata/sectic.html

4. Section-level Public Land Survey
This file was derived from SECTIC24K section corner data, using a routine which inserts line segments between point section corners. See http://deli.dnr.state.mn.us/metadata/pls_sectpy3.html

 
Section 2 Data Quality Information Top of full metadata Top of page
Attribute Accuracy No statistical attribute assessment has been performed. All township and range numbers, and sample section and quarter-quarter section identifiers were plotted at a 1:100,000-scale to test for proper label assignments. Government lot information was visually checked by plotting at a 1:48,000-scale and comparing the plot with the 1936 Mn/DOT Map. Information that didn't match was flagged (see Section 5, Entity and Attribute Information).
Logical Consistency Data have been topologically structured and verified.
Completeness Township, range and section areas are complete statewide. Quarter and quarter-quarter section lines have been calculated and are complete as computed within each township.
Horizontal Positional Accuracy The following comment covers data developed under the PLSS process (see Section 1 - Time Period of Content; process = PLSS and Section 2 - Lineage; process = PLSS).

Township and range lines were tested on two files, Anoka and Battle Lake, by the USGS National Mapping Division's Mid-Continent Mapping Center. The Center submitted the following evaluation to LMIC on September 1, 1993 in a letter from Mapping Center Chief Merle E. Southern: 'The positional accuracy of the Minnesota LMIC PLSS data evaluated met most of our recently adopted acceptance/rejection criteria. Tests of three thirty-minute segments all showed standard errors for x and y to be 5-mils [0.005 inch] or less. Tracking test on two segments were generally acceptable -- one line was encountered that was 12-mils off. No deviations of more than 11-mils are allowed. Shaping of line work was acceptable.'
Vertical Positional Accuracy Not applicable
Lineage The TRSQ data set was developed from a series of client projects conducted at LMIC. The initial effort began in 1990 when the Department of Natural Resources Engineering Division contracted with LMIC to help map federal, state and county lands in Minnesota. This effort, funded by a grant recommended by the Legislative Commission on Minnesota Resources, resulted in the publication of maps identifying public recreational lands. These Public Recreation Inventory Maps (PRIM) used U.S. Geological Survey 1:100,000-scale separations containing information about roads, railroads, rivers and lakes, as well as the basic network of land survey lines. The survey lines consisted of state, county, township, range and section boundaries but not quarter-quarter sections. To prepare a public ownership layer that took advantage of digital information available from DNR and LMIC, LMIC constructed a quarter-quarter section map base that complemented the USGS separations. This was done between 1990 and 1992 for 16 of the 71 quadrangles that cover Minnesota (see Section 1 - Time Period of Content; process = PRIM). LMIC used the following procedure:

1. Digitized section lines from USGS 1:100,000 paper maps for the 16 requested 30-by-60-minute quadrangles.

2. Added section corner tics at the intersections of the digitized section lines.

3. Created quarter sections and quarter-quarter sections using the LMIC-developed program GEN40 (undocumented). GEN40 used two sources of information: 1. the section corner coordinates, and 2. a list of the number of government lots within a quarter-quarter section (GLOT List). This undocumented list had been compiled at LMIC in the late 1980s from a 1936 series of annotated maps produced by the Minnesota Department of Transportation and various other sources. If the coordinates indicated that a section was regularly shaped (its section lines were 1,308 feet long) and if the GLOT List did not indicate the presence of government lots, GEN40 evenly bisected the lines connecting the corner coordinates to create quarter-quarter sections. Otherwise, GEN40 used a default distance of 1308 feet to create as many quarter-quarter sections as possible. Check plots were made and any areas in which the program had extended lines too far or not far enough were noted (this could occur at lake boundaries or at the state boundary). In these cases, lines were manually digitized or clipped to ensure that the survey line network was complete.

4. Labeled each quarter-quarter section with its county, township, range, section and quarter-quarter section identification. When government lots were present, GEN40 assigned codes indicating the number of government lots and the lowest lot number if a quarter-quarter section contained more than one lot. Government lot boundaries and meander lines around lakes were not digitized.

5. Produced a color check plot at a scale of 1:48,000 in order to compare it visually with the Minnesota Department of Transportation's 1936 county highway map series (Mn/DOT Map), which contained information on government lots. Any discrepancy between the GLOT List and the Mn/DOT Map for a particular quarter-quarter section was noted in the attribute table. The attributes were not changed since there was no basis for determining which information was correct.

In 1993 and 1994, an additional 38 quadrangles were completed with funding provided by the U.S. Department of Justice, DNR and LMIC. Seven quadrangles were created at the request of the Metropolitan Council. Work began in August 1995 to complete the remaining 10, with funding provided by the Board of Water and Soil Resources, and was completed in 1996. The process for these 56 quadrangles (see Section 1 - Time Period of Content; process = PLSS) was the same as the PRIM process outlined above except that the section lines were digitized from stable base mylar separations instead of paper maps.

6. The original data set was converted from NAD27 to NAD83. County tiles were created from the 30' x 60' tiles. Statewide files (section, township, county and state boundaries) were created by dissolving on each of the CTRSQ items in succession. (Note: since two methods were used to create TRSQ (PLSS and PRIM), these dissolved layers are not identical, although very close, to those created for LMIC's TRS data set.) ARC/INFO coverage format was converted to export and shapefile formats.

Section 5 Entity and Attribute Information Top of full metadata Top of page
Entity and Attribute Overview The Public Land Survey System features described in this data set are represented as attributed polygons and label points. The following information is included for each quarter-quarter section polygon:

1. FIPS_COUN: the Federal Information Processing Standard three-digit county code: Values are: 1-173.

2. COUN: a two digit county code. Values are: 1-87.

3. TOWN: a three digit PLSS township number. Values are: 26-168. Direction is assumed to be north. Township 58 1/2 in Range 17 (St. Louis County) is numbered 58. See FRACTION_TWP code to distinguish from Township 58.

4. RANG: a two digit PLSS range number. Values are: 1-51. Range 42 1/2 in Townships 159 and 160 (Roseau County) is numbered 42. See FRACTION_TWP code to distinguish from Range 42.

5. DIR: a one digit direction indicator: East = 1, West = 2.

6. SECT: a two digit PLSS section number. Values are: 1-36.

7. QQ_OR_GL: a two digit field that can contain either the quarter-quarter section or government lot. The field is meant to ease linking (relating) of external data.

8. FRACTION_TWP (FRACTION_T in shapefile format): a flag to indicate whether the township is a fractional (half) one: Y = Yes, N = No.

9. QQ_LABEL: a character field that can be used to label the quarter-quarter section, e.g., NENE.

10. QQ_SECT: two digit quarter-quarter section number. Values are: 01-99 (typically, each digit ranges between 1 and 4). The first digit indicates the quarter section quadrant, and the second digit indicates the quarter-quarter section quadrant. Both begin in the NE corner and increase moving counter-clockwise (e.g., 23 = NW SW, or 'the southwest quarter of the northwest quarter'). The 0 and 5-9 digits are used when government lots exist outside the boundaries of the standard section.

11. ACRES: area in acres calculated from the data set for each PLSS subdivision. This value represents a calculated value from the digital data set. It DOES NOT represent the results of a land survey.

12. CTRSQQ: combination of attributes 1 & 3 - 7, showing County, Township, Range, Direction, Section and Quarter-quarter section.

13. TRSQQ: combination of attributes 3 - 7, showing Township, Range, Direction, Section and Quarter-quarter section.

14. CTRSQ: combination of attributes 1 & 3 - 7a (the first digit of 7), showing County, Township, Range, Direction, Section and Quarter section.

15. TRSQ: combination of attributes 3 - 7a (the first digit of 7), showing Township, Range, Direction, Section and Quarter section.

16. NUM_OF_GL: when they are present, the total number of government lots assigned to a quarter-quarter section. Values are: 1-10.

17. GL_A through GL_J: the two digit lot number for each government lot indicated in NUM_OF_GLOTS. This number was assigned during the original land survey and subsequent resurveys. Values are: 1-99.

18. PROB_FLAG: a field indicating conflicting government lot information. Two sources were used to determine the presence of government lots and their identifying numbers. The first was a 1936 series of annotated county maps produced by the Minnesota Department of Transportation (Mn/DOT). The second was a list that originated with the 1936 information and was subsequently updated and modified, without adequate documentation (GLOT List). This item indicates whether these two sources match or do not match (only the lowest government lot number was shown on the checkplot, so higher lot numbers could not be compared). Match = 1; Discrepancy exists = 2.

19. COMMENT: a description of government lot discrepancies. For each parcel flagged as not matching in PROB_FLAG, this item describes the action that would need to be taken to modify the GLOT List in order to have it match the 1936 MnDOT Map. These changes were not done since there was no means of determining which information was correct.
a. Government lot number would need to be deleted
b. Government lot number would need to be added
c. Government lot number would need to be changed
d. Lowest government lot number matches (however, other lot numbers may not match)
e. Lowest government lot number does not match (and other lot numbers may not match)
f. Multiple government lot numbers would need to be created
g. Multiple government lot numbers would need to be deleted

20. X-COORD and Y-COORD: the x, y coordinates of an internal label point for each quarter-quarter section recorded in UTM units: meters, extended zone 15, NAD27.

21. MATCH: open field that can be used in linking (relating) this file with other data containing PLS information.


The TR file includes the following additional field:

1. TWP_LABEL: a character field used to label townships, e.g., T168 R35W.


Statewide files include the following fields:

1. FIPS_STATE: Federal Information Processing Code for Minnesota, value is 27.

2. COUN_UC: county name, upper case

3. COUN_LC: county name, mixed case

4. COUN_AB: county name abbreviation (first four letters in upper case)


The MN_100K file includes the following fields:

1. NAME_UPPER_Q100: 100K quad name, upper case

2. MINN_Q100_CODE: LMIC's 100K quad code

3. USGS_Q100_CODE: U.S. Geological Survey's 100K quad code

4. NAME_ABBREV_Q100: 100K quad name abbreviation (first 5 characters in upper case)


The MN_LAKE file includes the following field:

1. FLAG: values are: Lake; Island
Note: the MATCH field value equals N for lakes and is left blank for islands.

Ordering Instructions As noted in the abstract, for most uses, TRSQ has been superseded by the Minnesota Department of Natural Resources' 1:24,000-scale 'Control Point Generated PLS' data set which is free online. See http://deli.dnr.state.mn.us/metadata/pls_fortypy3.html for more information. Also, many county surveyors offices have more accurate PLS data sets. For county webpages and contact information, see http://www.state.mn.us/cgi-bin/portal/mn/jsp/content.do?az_type=description&subchannel=-536879913&programid=536879800&sc3=null&sc2=null&id=-8494&agency=NorthStar .

If you decide you want to order TRSQ, contact LMIC. The data is available in three formats, each of which is on a 2 CD set for $75: ARC/INFO coverage, ARC/INFO export, or shapefile. All CD sets are county tiles, NAD83 and also include the following data sets derived from TRSQ: sections, townships, county boundaries and state boundary.

Please contact LMIC to place a custom order if you need the data in 30' x 60' tiles or in NAD27.

Pre-payment is required, either by check or purchase order.

To download a SAMPLE file (Ramsey County) from this data set to assess whether the data will meet your needs before you order, go to LMIC's FTP site at: ftp://ftp.lmic.state.mn.us/pub/data/admin_poli . Download a self-extracting 'ZIP' file called trsqrams.exe (631 KB) which will contain the following:

- An Arc Export file (.e00) of Ramsey County (1.8 megabytes).
- Metadata (.htm) file for the data set
- NOTICE.RTF, an important notice about this data set that can be read by most word processing software, and an ascii text version of the same notice (NOTICE.TXT)

After downloading this self-extracting 'zip' file, simply execute (run) the file. (For example, you can double click it from Windows Explorer or File Manager). Doing this will automatically extract the sample files described above.
