A New High-Resolution National Map of Vegetation Ecoregions Produced Empirically Using Multivariate Spatial Clustering
Entry ID:
ORNL_MGC
Summary
Abstract:
A parallel supercomputer was used to divide the conterminous 48 states of
the United States into 1000, 2000, 3000, 5000, and 7000 ecoregions with relatively homogeneous values of elevation, edaphic, and climatic variables using an iterative multivariate clustering technique. Resolution of the clustered maps is 1 square kilometer; each national map has over 7.7 million cells. Each cell has nine ...
