Definitions

 

Rocky Mountain Region GIS Data Library

The following are definitions of the terms as used on this web site.

 

Abbreviations
(Administratively Combined Forests and Grasslands)
ARP - Arapaho and Roosevelt National Forests and Pawnee National Grassland.

GMUG - Grand Mesa, Uncompahgre, and Gunnison National Forests.

MBR - Medicine Bow and Routt National Forests and Thunder Basin National Grassland.

NNF - Nebraska and Samual R. McKelvie National Forests and Buffalo Gap, Fort Pierre, and Oglala National Grasslands.

PSICC - Pike and San Isabel National Forests and Cimarron and Comanche National Grasslands.
Administered Area Divisions of aggregated National Forests and National Grasslands managed by specific administrative offices.
Administrative Offices Regional Office (RO), Supervisor Office (SO), and Ranger District Office (DO) locations.
Allotments Designated areas of land available, under permit, for livestock grazing.
Basic Ownership Depiction of Forest Service surface estate parcel ownership as it existed at a specific point in time.
Campground A developed or undeveloped designated overnight camping site which may or may not have common public amenities.
Data Dictionary Description of the meaning of database field names, data type, precision, and content length.
Fire Dispatch Area Primary emergency response area.
Fire Dispatch Centers A resource staging location.
Forest System Road A motor vehicle travel way over 50 inches wide. May include state, county, municipal, and private roads within a National Forest.
Forest System Trail A designated thoroughfare under 50 inches in width that is maintained for the free passage of people, livestock, and off highway vehicles (where permitted).
Geospatial The combination of spatial software and analytical methods with terrestrial or geographic data sets. 
GeoTIFF Georeferenced TIFF format raster imagery.  
KML Keyhole Markup Language, an XML-based language schema for expressing geographic annotation and visualization of a set of features using various Virtual Globe geobrowsers.
KMZ Zipped KML files with a .kmz extension
Metadata Metadata describes other data. It provides information about a certain item's content. In geographic information systems (GIS) it functions the same way as a card in a library's card catalog describes a book. Metadata describes the data resource to help determine whether its content is suitable for a user's purposes. It contains a description of the data's accuracy, scale, source, history, timeliness, and use restrictions to help determine if or how the data may be properly used.
PLSS Public Land Survey System. The government established land survey Meridians, Township & Range, and Section grids.
Proclaimed Boundary Congressionally designated boundaries of National Forests. Some tracts of private, state, and/or other federal agency lands may be located within a proclaimed boundary.
Ranger District Generally, the smallest defined management unit. A single Ranger District may manage lands on multiple National Forests.
Regional Office Main office for the designated region. This office supports and coordinates with all National Forest ranger districts and supervisor offices within the region.
Rocky Mountain Region The majority of National Forest Service lands contained within Colorado, Kansas, Nebraska, South Dakota, and Wyoming.
Shapefile A popular geospatial vector data format for geographic information systems software. It is developed and regulated by ESRI as a (mostly) open specification for data interoperability among ESRI and other software products. A "shapefile" commonly refers to a collection of files with ".shp", ".shx", ".dbf", and other extensions on a common prefix name (e.g., "lakes.*"). The actual shapefile relates specifically to files with the ".shp" extension, however this file alone is incomplete for distribution, as the other supporting files are required.

Shapefiles spatially describe geometries: points, polylines, and polygons. These, for example, could represent water wells, rivers, and lakes, respectively. Each item may also have attributes that describe the items, such as the name or temperature. (Wikipedia) 
Supervisor Office Central office of a National Forest. This office may oversee Ranger districts on multiple National Forests.
Trailhead The point of origin of a designated trail. It may or may not have developed amenities.
Wilderness Areas National Forest lands that have recognized wilderness status or designation.
