Description:
Abstract:
This is a polygon coverage of the Major Ecosystems of Alaska map unit boundaries delineated by the Joint Federal-State Land Use Planning Commission for Alaska in 1973 at 1:2,500,000-scale.
Purpose:
This data will be used primarily to display the location of Major Ecosystems of Alaska at a state-wide scale. It is not recommended for local or regional analysis due to the small scale of this coverage.
Supplemental_Information:
Procedures_Used The original version of this digital coverage was generated by the US Environmental Protection Agency Environmental Research Laboratory, Corvallis, Oregon, around 1991. The procedures used to create this coverage were digitizing the major units from the original map. Revisions Reviews_Applied Related_Spatial_and_Tabular_Data_Sets None.
