The FSGeodata Clearinghouse (Forest Service Geodata Clearinghouse) is an online geospatial data portal for the US Forest Service. The clearinghouse provides access to vector (topographic and Land Status Record System - LSRS) and raster data, maps and other data sets to Forest Service personnel a...

Contour lines and corresponding elevations in feet for the Tongass National Forest. Elevation can be displayed at 100 foot intervals. The contour lines can also be displayed at 200 foot and 500 foot intervals. The linework was digitized from scanned USGS topographic maps.

Terrain aspect polygons derived from the 60 meter DEM (digital elevation model) data using the custom script - wildaspect.aml, from DEM's produced in the late 1990's.

This dataset contains polygons depicting ranges in elevation that were created using the dem60 tong_lat lattice and the Tongass wide VCU dataset.

Terrain aspect polygons derived from the 20 meter DEM data using the custom script - wildaspect.aml

A map of local-scale ecosystems (ecotypes) that encompasses the Brooks Range, Brooks Foothills, and Beaufort Coastal Plain ecoregions was compiled using vegetation structure associated with existing landcover maps derived from satellite image processing as well as physiography (i.e., coastal, flo...

The Preliminary Classification of Terrestrial Ecosystems in Southeast Alaska is based on 4 major data layers: USDA Forest Service Existing Vegetation database, the National Wetland Inventory, the USDA Forest Service Landforms and Karst from USFS soils and karst inventories. These layers were merg...

Traditional geospatial education tools such as maps and computer screens don't convey the rich topography present on Earth. Translating lines on a contour lines on a topo map to relief in a landscape can be a challenging concept to convey.A partnership between Alaska EPSCoR and the Geographic Inf...

This data set is the result of an effort to map the distribution of terrestrial ecosystems across the Alaska-Yukon Arctic ecoregion. The hierarchical classification system integrates physiography (coastal, floodplain, and alpine zones), topography, vegetation structure, and bedrock geology.
