The "Distribution of EMAP Grid Hexagons and Points for Biodiversity
Research" data sets are available at:
'http://www.nr.usu.edu/docs/archive/archive.html'
Three README files of documentation are available in this directory
describing the coverage, projection, and content of the data sets.
The following was abstracted from the first README file included in
the directory:
"This is the first of five files for distribution of the EMAP 635
square kilometer grid hexagons and points for application in
biodiversity research. Two additional README files explain various
aspects of the grid and its distribution. The file 'ushexes.geo'
contains the set of tessellation hexagon boundaries for the
conterminous United States. The file 'uspoints.geo' contains the
center points of the hexagons. As we have proposed for the national
biodiversity and landscape assessment, these hexagons (and the point
grid from which they are derived) are taken from the so-called
"unrandomized" version of the EMAP grid."
