Original Land Survey Bearing Trees

Metadata created using Minnesota Geographic Metadata Guidelines


Metadata Summary

Originator Minnesota DNR - Division of Ecological Services - County Biological Survey
Abstract A point database of bearing trees used as referrences or landmarks during the original Minnesota Public Land Srvey (PLS). A variety of information are stored about bearing trees that aid in their use as indicators of vegetation conditions present at the time of the survey. This database is described in greater detail in the publication: 'Minnesta's Bearing Tree Database', by John Almendinger, Biological Report No. 56, Minnesota Department of Natural Resources, 1997.

Title Original Land Survey Bearing Trees
Abstract A point database of bearing trees used as referrences or landmarks during the original Minnesota Public Land Srvey (PLS). A variety of information are stored about bearing trees that aid in their use as indicators of vegetation conditions present at the time of the survey. This database is described in greater detail in the publication: 'Minnesta's Bearing Tree Database', by John Almendinger, Biological Report No. 56, Minnesota Department of Natural Resources, 1997.
Use Tips
Purpose The data set is one source of information for scientists wishing to model environmental and ecological conditions present at the time of the original PLS survey. It contains enough potential sources of error (which require sophisticated analysis to account for) that casual use of the database, in its raw form, for critical decision-making is discouraged.

Section 2 Data Quality Information Top of full metadata Top of page
Attribute Accuracy Source table PVEG_BTREEPT3.PAT: These data are derived from the Bearing Tree Database, which is in turn derived from a source (original land surveyor notes) which contains known deficiencies that impact the accuracy of attributes within the database. The purpose of the land srvey was land subdivision. The collection of information on tree species and vegetation community typing was an ancillary activity, and the accuracy of tree species typing is known to suffer as a result. Additionally, between one and five percent of the records within the database are known to be incorrect as a result of transcription errors and/or illegibility in source manuscripts. DNR Biological Report 56 (refenced in the abstract to this description) provides essential information in the handling of attribute errors within the database.
Logical Consistency Data are topolocially correct using ARC/INFO 7.0.4.
Completeness The data extends across the state although bearing trees were not used in many areas (owing to the fact that much of the state was unforested at the time of the survey). Therefore, extensive portions of the prairie and marsh landscapes do not include bearing trees.
Horizontal Positional Accuracy Source layer btreept3: The Bearing Tree Database should not be treated as an accurate PLS database. Most of the data are not derived from actual bearing and distance offsets from the corner locations. Instead, they are the product of a standardized offset applied in the direction indicated in the surveyor's notes. Therefore, bearing tree locations within the database are idealized and cannot be considered correct. Positional offsets from correct positions could be as much as 200 meters in some cases.
Vertical Positional Accuracy Source layer btreept3: Not Applicable
Lineage Attribute Lineage for source table PVEG_BTREEPT3.PAT: These data are derived from the Bearing Tree Database, which is in turn derived from a source (original land surveyor notes).
