Description  Back to Top

GEOPACK is a comprehensive geostatistical software package that allows both novice and advanced users to undertake geostatistical analyses of spatially correlated data. The program generates graphics (i.e., linear or logarithmic line plots, contour and block diagrams); computes basic statistics (i.e., mean, median, variance, standard deviation, skew, and kurtosis); runs programs for linear regression, polynomial regression, and Kolomogorov-Smirnov tests; calculates linear estimations and nonlinear estimations; and determines sample semivariograms and cross-semivariograms. GEOPACK allows users to incorporate additional programs at a later date without having to alter previous programs or recompile the entire system.

Minimum System Requirements  Back to Top

GEOPACK has been written using a combination of Microsoft® FORTRAN and C programming languages and runs on IBM®-compatible microcomputers such as the PC-AT, Compaq®-286, -386, Zenith®, etc. using an MS-DOS® operating system (ideally version 3.30 or greater) and 640 K memory. GEOPACK does not require a math coprocessor but will use one if it is available. A virtual disk can be used to increase operating efficiency if it is defined to be the temporary storage directory. GEOPACK also requires that the ANSI.SYS driver be installed for the screen output to perform properly. GEOPACK requires hard disk storage of about 4 Mbytes and either a CGA, EGA, VGA or Hercules® graphics adapter and the appropriate monochrome or color monitor.

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

Installing the Program:  Back to Top

Three files are available for download

To download and install Geopack the following procedures MUST be followed:

  1. View the online User’s Manual (geoeas.pdf) file for further installation instructions.
  2. Download the 2 files GEOPACK1.ZIP and GEOPACK2.ZIP
  3. After the downloads have completed, unzip GEOPACK1.ZIP to a blank formatted 3.5 high-density diskette labeled "GEOPACK Disk 1".
  4. Unzip GEOPACK2.ZIP to a blank formatted 3.5 diskette labeled "GEOPACK Disk 2".
  5. Put the disk labeled "GEOPACK Disk 1" into the 3.5" drive.
  6. From the DOS prompt, change drives to your 3.5" drive
  7. An installation program is supplied with GEOPACK to facilitate the installation of GEOPACK onto a hard disk. To completely install GEOPACK, at least 4 Mbytes of free space must be available on the hard disk. The installation program can be started by typing either: "A:INSTALL C:" (with C: being the destination drive and path), or "A:INSTALL". If the optional source drive and destination drive and path are not specified, the program will provide prompts for this information. The source drive can be any legal floppy drive and the default value is A:. The destination drive and path indicates the hard drive and subdirectory for the "root" of the geostatistical programs. The default destination is C:\GEOPACK. It is advisable to specify a destination drive and subdirectory since a number of programs are copied to this subdirectory and could be accidentally deleted if only a drive (i.e., C:) is specified, since typically root directories are used to store a variety of programs. If any of these programs are deleted, GEOPACK may produce unpredictable results.
  8. Follow the on-screen directions and see the User's Manual.

Before GEOPACK will operate correctly, the computer must have a specific configuration. To install GEOPACK, several modifications to the computer must be made. These are described in more detail below.

  1. A temporary storage directory must be created. This is done automatically.
  2. An environment variable must be set. The AUTOEXEC.BAT file must be altered. GEOPACK will operate properly only if the environment variable %GEODIR% (the "%" are used to indicate an environment variable) is set to the root of the geostatistical programs. To set this variable the following line should be added to the AUTOEXEC.BAT file where C:\GEOPACK is the primary subdirectory for the geostatistical programs:

    SET GEODIR=C:\GEOPACK

    In the user-defined menus (described in Section 2.5.d of the User’s Manual) whenever GEOPACK sees "%GEODIR%" it will substitute "C:\GEOPACK" so that a command: %GEODIR%\SHOWDIR would be the same as C:\GEOPACK\SHOWDIR. Note, the above command can also be typed at the MS-DOS prompt prior to starting GEOPACK. After typing the SET command given above, if the DOS reply: "Out Of Environment Space" appears, the user should consult the DOS manual about SHELL commands.

    The installation program creates a file that contains the system default settings. This file may require modification before all of the options on the USER and other menus become active. Before making any modifications, see Section 2.5.c of the User’s Manual.
  3. A system parameter file must be created. This is done automatically. You will need to modify this file (see Section 2.5.c of the User’s Manual) to add the names of the editor, line and contour graphics, data base management system, etc. you have available.
  4. If you have a HERCULES graphics card, you must run MSHERC.COM prior to starting a GEOPACK session. This program should be put in the AUTOEXEC.BAT file.
  5. The ANSI.SYS driver (see your MS-DOS manual) must be installed in the CONFIG.SYS file. This is done by adding a statement like: DEVICE C:\DOS\ANSI.SYS to the CONFIG.SYS file. Be sure that the correct path for ANSI.SYS is used.
