资源简介：
This dataset contains the White Mountain National Forest Boundary. The boundary
was extracted from the National Forest boundaries coverage for the lower 48 states,
including Puerto Rico developed by the USDA Forest Service - Geospatial Service and
Technology Center. The coverage was projected from decimal degrees to UTM zone 19.
This dataset includes administrative unit boundaries, derived primarily from the
GSTC SOC data system, comprised of Cartographic Feature Files (CFFs), using ESRI
Spatial Data Engine (SDE) and an Oracle database. The data that was available in SOC
was extracted on November 10, 1999. Some of the data that had been entered into SOC
was outdated, and some national forest boundaries had never been entered for a
variety of reasons. The USDA Forest Service, Geospatial Service and Technology
Center has edited this data in places where it was questionable or missing, to match
the National Forest Inventoried Roadless Area data submitted for the President's
Roadless Area Initiative. Data distributed as shapefile in
Coordinate system EPSG:26919 - NAD83 / UTM zone 19N.
