Description
Abstract
Major Land Resource Area (MLRA) boundaries for Alaska.
Purpose
This coverage is intended as a basemap for US national level natural resource
analysis.
Supplemental_Information
Procedures_Used
This coverage contains the Major Land Resource Area (MLRA) boundaries for
Alaska. MLRA boundaries were revised in the mid-1990s from
earlier versions established in the 1970s and 1980s by the U.S. Department of
Agriculture (USDA) Natural Resources Conservation Service (NRCS), formerly the
Soil Conservation Service (SCS). The revised MLRA boundary coverage was
digitized at the Soil Survey Center in Lincoln, Nebraska, the most recent
version of which was completed in January of 1997. Buffer polygons were added
to the U.S. national boundaries and shoreline by NRCS National Cartography and
Geospatial Center in Fort Worth, Texas, for use with NRCS National Resources
Inventory (NRI) digitized sample sites. These buffered boundaries were later
removed by the NRCS National Headquarters office, Resources Inventory and Assessment Division
(RAD) in May 2000, and the national shoreline and outer boundaries were made
to conform to standard boundaries established for NRI Map Room series
maps (http://www.nrcs.usda.gov/technical/land/). Those standard U.S. national
boundaries and shoreline are based on 1:2,000,000 scale 8-digit hydrologic
unit coverage obtained from the U.S. Geological Survey, circa 1990, and were
edited by the National Center for Resource Innovations (NCRI) in Washington,
DC, and subsequently by NRCS/NHQ/RAD.
Revisions
The coverage was last updated in 2002.
Reviews_Applied_to_Data
This coverage has received no formal review.
Related_Spatial_and_Tabular_Data_Sets
This MLRA coverage is intended to have the same shoreline and outer boundaries
as other coverages available in the NRCS NRI Map Room series (available
online at http://www.nrcs.usda.gov/technical/land), although their precise
correspondance has not been thoroughly verified. These coverages include
counties, 8-digit hydrologic units, and Federal lands, derived from USGS
coverages, circa 1990.

Areas of the United States" for a look at an earlier version of the map and
an explanation of MLRA and LRR designations.

Use_Constraints:
This coverage is designed for national, regional and state level analysis. It
may or may not be appropriate for use at larger scales. This map does not meet National Map Accuracy Standards. An improved version
of the currently established MLRA lines is in development.

Data_Set_Credit
Sharon Waltman (swaltman@nssc.nrcs.usda.gov), USDA/NRCS National Soil Survey Cen
boundary lines, excluding the U.S. national outline and lines immediately
attached to it, which were replaced by later edits.
Kevin Grantham, USDA/NRCS National Cartographic and Geospatial Center added
buffer polygons to the U.S. national boundaries.
Dean Oman (dean.oman@wdc.usda.gov), USDA/NRCS National Headquaters, Resources Inventory and Assessment Division, replaced the U.S. national shoreline and outer boundaries
(including buffer polygons added by Kevin Grantham) with boundaries
established for NRI Map Room series maps.
(http://www.nrcs.usda.gov/technical/land/)
George Muehlbach, National Center for Resource Innovations (NCRI), Washington,
DC, made the initial shoreline and national boundary adjustments to the
1:2,000,000 scale coverages obtained from the United States Geological Survey,
which also serve as the shoreline and outer national boundaries for this MLRA
coverage.
