Distribution of EMAP Grid Hexagons and Points for Biodiversity Research

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."
