Description  Back to Top

GEOEAS is a collection of interactive software tools for performing two-dimensional geostatistical analyses of spatially distributed data. The principal functions of the package are the production of grids and contour maps of interpolated (kriged) estimates from sample data. GEOEAS can produce data maps, univariate statistics, scatter plots/linear regression, and variogram computation and model fitting.

Minimum System Requirements  Back to Top

This system was designed to run under DOS (Disk Operating System) on an IBM PC, XT, AT, PS2, or compatible computer. Graphics capability is not required, but is highly recommended, as most programs will produce graphics output. Graphics support is provided for the Hercules graphics card, the Color Graphics Adapter (CGA), and the Enhanced Graphics Adapter (EGA). At least 512 kilobytes (Kb) of random access memory (RAM) is required, but 640 Kb is recommended. An arithmetic co-processor chip is strongly recommended due to the computationally intensive nature of the programs, but is not required for use. Programs may be run from floppy diskette, however, a fixed disk is required to use the programs from the system menu. The system storage requirement is approximately three megabytes. For hardcopy of results, a graphics printer (IBM graphics compatible) is required. Support is provided for plotters which accept HPGL plotting commands.

Installation and Start-Up  Back to Top

Getting Started:

You will need unzipping (compression) software to uncompress ZIP files. If you need to load compression software on your computer, free software is available for download on the internet at the following sites:

Leaving EPA -> http://www.pkunzip.com -  PKUNZIP home page
Leaving EPA -> http://www.info-zip.org/ - InfoZip Wiz

Installing the Program:

Two files are available for download:

  1. View the online User's Manual (geoeas.pdf) file for further installation instructions.
  2. Go to Windows Explorer and create a directory (folder) named GEOEAS.
  3. Download geoeas.zip to the new GEOEAS directory.
  4. From the GEOEAS directory you created, run geoeas.zip by double clicking on the file.
  5. Unzip the files to the same GEOEAS directory.
  6. Download and review the Users Manual (geoeas.pdf) for instruction on running the model.
  7. Start the GEOEAS program by double clicking on the GEOEAS.EXE file. A description of other executible files provided as part of the GEOEAS program are provided below:

    GEOEAS.EXE - the system menu program
