The Geo-EAS (Geostatistical Environmental Assessment Software) software package consists of thirteen programs written for IBM PC - compatible computers. The principal functions of the package are the production of 2-dimensional grids and contour maps of interpolated (kriged) estimates from sample data. Other functions include data preparation, data maps, univariate statistics, scatter plots/linear regression, and variogram computation and model fitting. Extensive use of screen graphics such as maps, histograms, scatter plots and variograms help the user search for patterns, correlations, and problems in a data set. Data maps, contour maps, and scatter plots can be plotted on an HP compatible pen plotter. Individual programs can be run independently; the statistics and graphics routines may prove useful even when a full geostatistical study is not appropriate. For ease of use, the programs are controlled interactively through screen menus, and use simple ASCII data files... Software Description: The software is written in the Fortran programming language for implementation on IBM-PC/XT/AT or compatible machines using the DOS 2.0 or higher operating system. Minimum memory required is 640K. Special features/requirements: Graphics monitor required (CGA, EGA, VGA, or Hercules); Math Coprocessor recommended.
