| Abstract | The PLS Control Point layer is a subset of the Control Point Inventory (CPI) database, consisting of section corners and some quarter section corners that were used to create the DNR Control Point Generated PLS layer. Section corner coordinates in CPI have been derived from a variety of sources, ranging from paper 7-1/2 Minute USGS quad maps to highly accurate modern ground surveys. Additional information regarding the Control Point Inventory, not included in this document, can be obtained through Larry Swenson in DNR?s Bureau of Engineering [651-297-3793]. |

| Section 2 | Data Quality Information | Top of full metadata | Top of page | |
| Attribute Accuracy | Source table PLS_CORNERPT3.PAT: Not specifically assessed. | |||
| Logical Consistency | Data are topolocially correct using ARC/INFO 7.0.3. | |||
| Completeness | All section corners within the data extent are included. Some half and quarter section corner locations have been eliminated. | |||
| Horizontal Positional Accuracy | Source layer cornrpt3: Variable. At its least accurate, the coverage contains points that are derived from manual digitizing of PLS section corners from 1:24,000 scale, paper, USGS quadrangles (listed as GISMO and SECTIC-24K points). At its most accurate, the coverage contains points that were collected using GPS units operating at a sub-meter level of accuracy. The QA (quality assurance) field in the point attribute table of these coverages contains a numeric code that indicates the method of how the coordinate position of a point was determined. The ACCURACY and METHOD fields contain the text descriptions for the related QA codes that describes the accuracy limits and collection method of the point. | |||
| Vertical Positional Accuracy | Source layer cornrpt3: Not Applicable | |||
| Lineage | Attribute Lineage for source table PLS_CORNERPT3.PAT: The PLS Control Points are a subset of the Control Point Inventory (CPI), a database maintained by the DNR, Bureau of Engineering, Survey Section. A majority of the points in CPI came from the GISMO or SECTIC-24K control point data sets. | |||

| Entity and Attribute Overview | Data Elements for Attribute Table PLS_CORNERPT3.PAT: TOWN: Three digit township (tier) number RDIR: Range direction RANG: Two digit range number GCDB_NUM: Locational reference system for every PLS corner in a township, which is unique only within each township. This numbering system is used by the Control Point Inventory and the Bureau of Land Management CMM software in processing the townships QA: Quality Assurance. Three-digit number that relates the method of how the coordinate position of a point was determined. This information comes directly from the Control Point Inventory. (See fields ACCURACY and METHOD for related information.) ACCURACY: Accuracy limit for the point based upon collection method and practical knowledge, assuming proper procedures were followed when the point's coordinate was determined. (Relates to QA field-- e.g. QA = 111, indicates +/- .5 feet) This information comes directly from the Control Point Inventory documentation METHOD: General method of collection for the point. (Relates to QA field) This information comes directly from the Control Point Inventory documentation PROJECT: Internal DNR project name. This information comes directly from the Control Point Inventory POINT_NUM: Control Point Inventory point number, unique within an internal DNR project MONUMENT: Listing of monument type, if in place. This information comes directly from the Control Point Inventory UPDATED: Date the database record was last updated. This information comes directly from the Control Point Inventory CERT: Tells whether the corner is certified or not. This information comes directly from the Control Point Inventory CERTBY: Explains who conducted the certification. This information comes directly from the Control Point Inventory DESCRIPT: Description of any pertinent geographic features related to the point, such as relationship of the point to roads, fences, etc. This information comes directly from the Control Point Inventory YR: REDEFINEd, beginning at column 120. Contains the last two digits of the year MO: REDEFINEd, beginning at column 122. Contains the two-digit month DY: REDEFINEd, beginning at column 124.
