Abstract:

Perimeters of fires that occurred in Montana that were compiled by the Northern Region Fire GIS staff from various sources. Fire perimeters were determined from digital capture procedures.

The original data from the Forest Service has been clipped to the boundaries of Montana by the State Library and converted to Montana State Plane Coordinates, NAD83, meters. The Forest Service data is available at http://www.fs.fed.us/r1/ecology/fire2000/.

Most of the narrative in this metadata is from the metadata provided by the Forest Service.

The data set includes perimeters of fires from the year 2000 that occurred in Montana on land administered by the USDA - Forest Service, USDI - Bureau of Land Management, USDI - National Park Service, USDI- Fish and Wildlife Service, Montana - DNRC, USDI - Bureau of Indian Affairs, the Confederated Salish and Kootenai Tribes, Idaho Department of Lands, and various private and county lands. This data set represents the compiled fire perimeters in the area encompassed by and adjacent to the Northern Region of the Forest Service. Fires mapped as part of Complexes are mapped as individual fires in this data set.

Occasionally, National Forests submitted fire perimeters as a Forestwide data set and these were not parsed to individual fires and posted to the Web site individually. Data represent the most current, compiled fire perimeters at time of publication. In addition, since many fires are still active, these data may not represent final perimeters.

Purpose:

The data set is being developed for a variety of Federal and State assessments pertaining to the spatial extent of the fires within or immediately adjacent to the Northern Region of the USDA - Forest Service.

Supplemental information:

These digital fire perimeters were developed from one or more of the following digital capture procedures; heads - up digitizing from hand- drawn perimeters, ground and/or aerial Global Positioning System coordinates, Infrared photography, a combination of the above procedures, or unknown derivation. Preliminary line and node error checking has been performed to remove dangles and overshoots. Polygons have been checked for closure and are attributed with Fire name, Arc/Info acres, and method of digital capture.

Spatial Data Organization Information:

Point and vector object information:

SDTS object type: G-polygon

SDTS object count: 205

Spatial Reference Information:

Horizontal coordinate system definition:

Grid coordinate system name: State Plane Coordinate System 1983

SPCS zone identifier: 2500

Lambert conformal conic:

Standard parallel: 45
Standard parallel: 49
Longitude of central meridian: -109.5
Latitude of projection origin: 44.25
False easting: 600000.00000

Planar distance units: Meters

Geodetic model:

Horizontal datum name: North American Datum of 1983
Ellipsoid name: GRS1980
Semi-major axis: 6378137.0
Denominator of flattening ratio: 298.257

Entity and Attribute Information:

Entity type label: ThermPower1992.dbf

Entity type definition: Point attribute table

Attribute label: FID

Attribute definition: Shapefile sequence number

Attribute label: Shape

Attribute definition: Feature geometry

Attribute label: Area

Attribute definition:: area of the polygon in square meters, Montana State Plane Coordinates

Attribute label: Perimeter

Attribute definition:: perimeter of the polygon in meters, Montana State Plane Coordinates

Attribute label: TEMPSTAT_I

Attribute definition: ID number from original coverage version of the data

Attribute label: ARC_ACRES

Attribute definition:: Area of polygon, in acres.

This does not seem to be an accurate calculation. It may have been derived from the polygon coordinates in an inappropriate coordinate system, or may be from a different version of the polygon.

Attribute label: FIRE_NAME

Attribute definition: Name of the Fire

Attribute label: Source

Attribute definition: Source of the data coordinates

Attribute label: Acres

Attribute definition:: Area of the polygon, in acres.

This was calculated from the current polygon geometry, in Montana State Plane Coordinates. Use of this coordinate system in Montana ensures that polygon area calculations will be within 0.1 percent of the correct geodetic value for the given coordinates.
