---++ GSLIB

Below is the detail information:

| DEVELOPED | 1992-1999 |
| AUTHOR | Clayton V. Deutsch and Andre G. Journel <br />Department of Applied Earth Sciences <br />Stanford University <br />USA |
| PLATFORM | Windows & UNIX |
| PURPOSE | Geostatistics in 2 and 3D |
| FUNCTIONS | + general statistics (histograms, probability plots) <br />+ declustering function <br />+ variogram and cross variogram calculations (2-D and 3-D) <br /><br />+ Simple and ordinary kriging <br />+ kriging with a trend model <br />+ kriging with an external drift <br />+ cokriging <br />+ Non linear kriging <br />+ indicator kriging and cokriging <br />+ indicator principal + component kriging (IPCK) <br />+ Soft kriging <br /><br />all these can be point or block kriging <br /><br />+ LU simulation <br />+ simulated annealing <br />+ sequential gaussian simulation <br />+ sequential indicator simulation (categorical or continuous variable) <br />+ turning bands simulation <br /><br />+ cross validation, jackknifing |
| CODES | Fortran 77 codes availabe |
| TIP | There are 3 versions of GSLIB: <br />The first version GSLIB 2.0 is free and codes (fortran 77) can be downloaded. <br /><br />The last versions, GSLIB 2.90 is free, written in fortran 90 and executables only can be downloaded. <br /><br />Note that you will also need the Xgam program to process *.var files from GSLIB and visualize variograms: have a look at <a target="_blank" href="http://www.engin.umich.edu/class/cee682/src/xgam/">www.engin.umich.edu/class/cee682/src/xgam/</a> - _link is broken, will be checked soon_ <br /><br /><br />Other people have written some software to make the use of GSLIB 2.0 more user friendly: <br /><br />+ UPFILE is a computer program running under windows to display in a raster format the output of data generated with GSLIB. <br />See <a target="_blank" href="http://www.ibrae.ac.ru/%7Emkanev/eng/Upfile.html">www.ibrae.ac.ru/~mkanev/eng/Upfile.html</a> - _link is broken, will be checked soon_ <br /><br />+ 3Plot also adds x,y co-ordinates to outputs from GSLIB. <br />See <a target="_blank" href="http://www.ibrae.ac.ru/%7Emkanev/eng/3plot.html">www.ibrae.ac.ru/~mkanev/eng/3plot.html</a> - _link is broken, will be checked soon_ <br /><br />+ The Geostats package from Cyze & Associates is a free utility which provides the user with a simple but useful windows interface to the codes. See <a target="_blank" href="http://www.cyze.com/product/geostats/">www.cyze.com/product/geostats/</a><br /><br />+ Check also [[SWWinVAM][WinVAM]] for the automatic modelling of the variogram output of GSLIB.<br /><br />+ Check also [[SWVISIM][VISIM]] (codes section of AI-GEOSTATS) |
