Metadata Summary

Originator Clearwater County Land and Forestry Department
Abstract The 1998 Forest Inventory data set is an ARC/INFO polygon coverage that encompasses the County Memorial Forest Land and Tax Forfeited Trust Lands of Clearwater County, Minnesota. The data set was developed by the Clearwater County Land and Forestry Department with assistance from private consultants: Pro-West and Associates, Walker, Minnesota; and the Land Management Information Center (LMIC), St. Paul, Minnesota. The data was interpreted from aerial photography (1:15,840 B&W IR) and field surveys of forest stands.

Section 2 Data Quality Information Top of full metadata Top of page
Attribute Accuracy Forest stands inventoried are interpreted from aerial photography and field surveys following the specifications of the Department of Natural Resources (DNR) Phase II Inventory Methods Manual. Accuracy limitations have not been established, however, boundaries of forest stands are inventoried respectively with ground features and reference points. The data set is accurate relative to the United States Geological Survey (USGS) Topographic Maps.
Logical Consistency The data set is topologically 'clean', however, a complete stand by stand quality control check is in the process.
Completeness The data set is complete. New additions and deletions of County Lands can occur and are updated annually.
Horizontal Positional Accuracy The data set is considered to meet the National Mapping Accuracy Standards at 1:24,000 (within approximately 50 feet of actual location).
Vertical Positional Accuracy Not applicable
Lineage PROCESSING STEPS FOR THE ANNUAL UPDATING OF THE DATA SET:

Timber sales for specific forest stands are established by utilizing the most recent plotted forest coverage maps to determine the aerial extent and surrounding covertypes of forest stands. Aerial photography is also utilized to establish reference marks in field. Field work is conducted to prepare the stand for harvesting including determining acreage and other necessary forestry items. After the forest stand has been harvested the forest stand is field checked again. This is required to determine the actual harvested area of the stand, and its boundaries in relation to reference mark, including forest trails, water bodies, and other forest stands.

The boundary of the harvested forest stand is completed in office by Department staff from aerial photography and transferred onto mylar. The mylar is then overlaid onto GIS produced base map templates for sections containing forest stands. In some situations, new forest stands (polygons) are mapped, or merged with adjacent forest stands.

These new forest stands (polygons) are provided to the GIS staff in the Department to be digitized into the respective township forest coverages. The data is digitized on a 4 inches = 1 mile template. Once digitized the coverage is topologically cleaned, edited and updated.

Upon completion of all forest stand updates in every township, the coverages are mapjoined producing a data set of forest stands countywide.

Section 5 Entity and Attribute Information Top of full metadata Top of page
Entity and Attribute Overview Data are referenced to the Minnesota Department of Natural Resources CSA Tatum Guide. The original categories used for the DNR Phase II Inventory were established in 1988 and have been modified only slightly over the years of generating Clearwater County forest inventory maps. The classes (attributes) for the data set are intended only for county staff use and interpretation. Listed below are the attributes of the forest coverage:

OWNER: Broad ownership category
SECTION: Standard PLS section
TYPE: Unique stand sequence number within each owner and PLS section
TOWNSHIP: PLS Township
RANGE: PLS Range
E_W: Differentiates between east and west ranges of the 4th Principle Meridian
COUNTY: Unique county codes
RAD: MN DNR Division of Forestry Area code
FOREST: State Forest code
OTHER: Code for any management unit other than state forest
COMP: Compartment number
ACQUI: Acquisition status of the land parcel
ADMIN: Administrator for the land parcel
CTYPE: Forest cover type classification code
CSIZE: Size class based on dbh of trees
CDENSE: Density class
UTYPE: Understory cover type
USIZE: Same as csize
UDENSE: Same as cdense
ACRES: Acreage of the stand
YEAR: The last 2 digits of the year in which the survey was done
TOPO: Topographic characteristics of the site
SI: Site index obtained using tree age and height
PHYS: Physiographic class (soil moisture)
AGE: Average stand age in years AT THE TIME OF SURVEY
BA: Basal area per acre
CORDS: The volume/acre in cords for all trees 5-15 inches dbh
MBF: Thousands of board feet/acre for trees 15+ inches dbh
COND: Condition class
TBR: Timber status, defines any restrictions on harvesting
SPP: Specie code of the main specie in the stand
DBH: Diameter at breast height of main specie
HEIGHT: Height (feet) of main specie
VOLUME: Volume per acre
DAMAGE: Damage code
AFFECT: Percentage affected by damage
MORTAL: Percentage of mortality in stand
SHRUBS: Shrub specie code
DISTR: Distribution pattern of shrub
DENSE: Density of shrubs
BROWSE: Amount of shrub available to deer
COVER: Ground cover code
RECON: Reconnaissance level
ORIGIN: Stand origin
ROAD: Distance to road in miles
SIGN: Significant feature(s) present in the stand
CARDS: Obsolete, used mainly as a flag for various unique applications

The remaining fields in this table are mostly repeating items of information collected for up to 8 co-dominant or sub-dominant tree species that make up the stand composition. This includes more information on species make-up of the stand understory.

The first set of these attributes are listed below (field names beginning with the string 'S2'). Subsequent sets (field names beginning with S3-S5) contain the same attributes and are not described here. The 2nd specie through 5th specie are of commercial size class, 5 inches dbh or greater.

S2SPP: Same specie codes as for SPP above
S2DBH: Diameter at breast height in inches
S2DST: Distribution of specie in the stand
S2VOL: Volume per acre
S2DAM: Damage codes
S2HAR: Harvest recommendation

MISC_CORD
MISC_BF

The next set of attributes are listed below (field names beginning with the string 'S6'). Subsequent sets (field names beginning with S7-S9) contain the same attributes and are not described here. The 6th specie through 9th specie are less than 5 inches dbh.

S6SPP: Same as all other specie codes
S6SIZ: 1 = 0-0.9 inch; 2 = 1-2.9 inches; 3 = 3-4.9 inches
S6DEN: Same as understory density class
S6DST: Same as other distribution codes
S6DAM: Same as other damage codes

REMS: Remarks, comments
