Forest Inventory: Becker County, Minnesota

This page last updated: 04/06/2007
Metadata created using Minnesota Geographic Metadata Guidelines


Metadata Summary

Originator Becker County, Minnesota
Abstract This ARC/INFO polygon coverage contains the base forest inventory data for Becker County. Polygons are identified by forest covertype, timber size class, and timber density class. Polygon data were originally photo-interpreted from unrectified 1:15,840 color IR aerial photography.
Browse Graphic none available
Time Period of Content Date 1998
Currentness Reference Photo-interpretation was originally from 1993 color IR aerial photography. Forest reinventory and updates are done on a cyclical basis for selected townships from most current color IR photography. Dates of photography vary. The latest reinventory date for each stand is stored in forest.pat under the item 'Year'.

Originator Becker County, Minnesota
Title Forest Inventory: Becker County, Minnesota
Abstract This ARC/INFO polygon coverage contains the base forest inventory data for Becker County. Polygons are identified by forest covertype, timber size class, and timber density class. Polygon data were originally photo-interpreted from unrectified 1:15,840 color IR aerial photography.
Purpose This coverage serves as one of the base coverages for forest management planning.
Time Period of Content Date 1998
Currentness Reference Photo-interpretation was originally from 1993 color IR aerial photography. Forest reinventory and updates are done on a cyclical basis for selected townships from most current color IR photography. Dates of photography vary. The latest reinventory date for each stand is stored in forest.pat under the item 'Year'.

Section 2 Data Quality Information Top of full metadata Top of page
Attribute Accuracy No statistical accuracy tests have been performed.
Logical Consistency Data are topologically structured and verified within PC ARC/INFO.
Completeness All covertype polygons are mapped for tax-forfeited lands within the completed townships. Coverage currently contains 8 of the most heavily forested townships. Additional townships will be added as funding allows.
Horizontal Positional Accuracy Unknown
Vertical Positional Accuracy Not applicable
Lineage Data Sources:
1:15,840 Color IR Aerial Photography (1993)
1:24,000 USGS 7.5-Minute Quadrangles

Processing Steps:
The data were originally photo-interpreted from 1993, 1:15,840 color IR aerial photography. Section lines were digitized from USGS 7.5-minute quadrangle maps and used to delineate quarter-quarter boundaries. Land boundaries were also transferred from the photos where needed. Where coincident lines existed (lakes, roads, section lines), lines digitized from the USGS quadrangle were used.
