Presettlement Vegetation

This page last updated: 2006-08-09 09:12:03.0
Metadata created using Minnesota Geographic Metadata Guidelines


Metadata Summary

Originator Minnesota DNR - Division of Forestry
Abstract Presettlement vegetation of Minnesota based on Marschner's original analysis of Public Land Survey notes and landscape patterns. Marschner compiled his results in map format, which was subsequently captured in digital format.
Use Tips This data has significant omissions. Many small polygons have not been captured. Some one by one-half degree blocks in the central portion of the state have large numbers of missing polygons. The data also exhibits significant positional off-sets, of up to one thousand feet in places. Use with caution.

Title Presettlement Vegetation
Abstract Presettlement vegetation of Minnesota based on Marschner's original analysis of Public Land Survey notes and landscape patterns. Marschner compiled his results in map format, which was subsequently captured in digital format.

Purpose To analyze presettlement vegetation patterns for the purpose of determining natural community potential, productivity indexes, and patterns of natural distrubance

Associated Data Sets

 
Section 2 Data Quality Information Top of full metadata Top of page
Attribute Accuracy Source table PVEG_MRSCHPY1.DBF: Existing polygons reflect Marschner's original interpretations, which were based on incomplete information. This data cannot be considered accurate or definitive.
Logical Consistency Data are topolocially correct using ARC/INFO 8.0.1. All polygons are closed and lines intersect where intended.
Completeness These data have significant omissions when compared to Marschner's original map. Several thousand small polygons are thought to have been omitted, principally in the prairie and transitional forest areas of the state.
Horizontal Positional Accuracy Source layer prvegpy1: Qualitative positional accuracy comparisons between water bodies in this data and the same features in larger scale sources suggests a range of positional offsets in the range of 500-700 feet as common, with the direction of the offset being variable. This is an expected deviation considering the 1:1M digitizing scale.
Vertical Positional Accuracy Source layer prvegpy1: Not applicable
Lineage Attribute Lineage for source table PVEG_MRSCHPY1.DBF: Unknown
Source Scale Denominator Source layer prvegpy1: 100000
