These infrastructure data were originally compiled by Audubon in 2014 and provided to the BLM Rapid Ecological Assessment (REA) project for the North Slope region. The data were updated by the Alaska Center for Conservation Science (ACCS) for the REA and released for public distribution on the BLM/REA website. The North Slope Science Initiative (NSSI) has updated the REA product using available high resolution orthoimagery as a reference base during manual digitizing. Roads within villages have been updated using Alaska Department of Transportation GIS data. Road features have been assigned oil and gas unit designations using Alaska Division of Oil and Gas GIS data. All locations are approximate. Neither the North Slope Science Initiative or contributors to this dataset shall be held liable for improper or incorrect use of the data described and/or contained herein. In an effort to provide the most comprehensive overview possible, we have incorporated many data sources, using a variety compilation methods. As a result there are a variety of limitations to the thematic and positional accuracy of these data. The appropriate use of these data is the responsibility of the user.

This data set represents an updated Ecological Subsection Map for Northern Alaska. This update includes permafrost mapping to include the following new layers: permafrost extent, massive ice, thaw settlement potential, segregated ice and thermokarst landforms.
A prior 2014 revision focused on correcting coding errors identified in the original 2012 version. The 2012 mapping effort focused on completing the the southern NPRA, improving mapping of glacial and outwash deposits within the Brooks Foothills, and improving consistency with existing surficial and bedrock geology maps in northern Alaska.
