WinGslib is an interface to the GSLIB programs contained in the book
written by Deutsch and Journel published by Oxford University Press, second
edition, 1997. The latest FORTRAN 90 GSLIB programs with dynamic memory
allocation are used. WinGslib is an interface to these programs; the GSLIB
programs are executed by WinGslib . WinGslib is a product of Statios LLC (see www.statios.com
for corporate information).
In summary, WinGslib allows import and export of the traditional GSLIB
parameter files to and from a user interface. The user interface permits
straightforward modification of the parameters, execution of the programs, some
error checking, and linkage to visualization. A project structure has been used
that permits users to specify a default location of data, parameter files, and
output files. The project structure simplifies organization and provides default
locations; however, the user has the flexibility to use data from any input
directory and write results anywhere.
WinGslib provides an interface to all 39 GSLIB programs with all options
enabled. The options in GSLIB are there for a reason and WinGslib recognizes all
of them. The programs are accessed through six menus:
- data manipulation
- postscript plots
- post processing
This organization is consistent with the chapters in the GSLIB book.
A help system is available for WinGslib and all GSLIB programs. The idea
behind WinGslib is to provide a user interface to aid in the use of GSLIB on a
PC. There is no direct help that would teach geostatistics. The user must have
an understanding of how the programs are used together to undertake a
The main WinGslib window provides three views:
Other features of WinGslib include:
- A tree structure to the left that shows all of the programs and parameter
files that have been executed. The parameter files can be re- executed or
results visualized by clicking the right mouse button.
- A batch file may be created, saved, loaded, and executed in the batch
window to the right. This makes repeated execution of many programs easy.
- The messages written by the GSLIB programs are displayed in the lower
window; the debugging and reporting output of GSLIB may be viewed.
- standard Windows file selection and save protocols are used
- labels are used in place of column numbers
- files and parameter files may be viewed by the click of a mouse button
- "plot" programs are available to combine multiple PostScript
plots to the same page.
