Description  
    Abstract
    Major Land Resource Area (MLRA) boundaries for Puerto Rico and the
    U.S. Virgin Islands.
     
     
    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 the
    U.S. Virgin Islands and Puerto Rico.  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, with additional minor edits performed 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.

None.
 
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
lines, excluding the shoreline and lines immediately attached to it, which
were replaced by edits described below.
 
Kevin Grantham, USDA/NRCS National Cartographic and Geospatial Center added
buffer polygons to the shoreline boundaries.
 
Dean Oman (dean.oman@wdc.usda.gov), USDA/NRCS National Headquaters, Resources Inventory and Assessment Division, replaced the shoreline 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.
