Geo-EAS is a scientific program written by the US 
Environmental Protection Agency.  Geo-EAS is a collection 
of interactive software tools for performing two-dimensional 
geostatistical analyses of spatially distributed data. 

The principal function of the package is the production 
of grids and contour maps of interpolated (kriged) estimates 
from sample data. Geo-EAS can produce data maps, univariate 
statistics, scatter plots/linear regression, and variogram 
computation and model fitting.
