Geo-EAS Platforms: Shareware - DOS, UNIX, SUN Geo-EAS, which stands for Geostatistical Environmental Assessment Software, version 1.2.1 was released by the USA EPA in May, 1990, although several minor revisions have since taken place in the source-code files. It is a collection of 13 interactive tools for 2D geostatistical analyses of spatially distributed data. The principal function is the production of 2D grids and contour maps of interpolated (kriged) estimates from sample data. The package is completely menu-driven and includes modules for data file management, data transformations, univariate statistics, variogram analysis, cross-validation, kriging, making contour maps, post plots, and line/scatter graphs. IBM graphics compatible printer and HP plotter output is provided. All data files are standard ASCII data files, making interchange with other packages easy. Fortran source code is also available. Typically up to 200 samples can be handled with the DOS version and with the UNIX version up to 1000 samples can be used with up to 48 variables modeled.
GeoPACK Platforms: Public domain - DOS GeoPACK Geostatistical Software System consists of a package of programs for conducting analyses of the spatial variability of one or more random functions. Includes basic statistics including: mean, median, variance, standard deviation, skew, kurtosis, maximum value, minimum value, linear regression, polynomial regression, and the Kolomogorov-Smirov test for distribution, and for calculating various percentiles of a selected data set. Variogram programs allow determination of a sample semi-variogram, the cross-semi-variogram, or a semi-variogram for combined random functions for a 2D spatially-dependent random function. Calculates ordinary kriging and co-kriging estimators in 2D and their associated estimation variance. Non-linear estimators such as the disjunctive kriging and the disjunctive co-kriging estimators can be also be determined. Graphics capabilities include linear or logarithmic line plots, contour plots, and block diagrams. Can be interfaced with any user-defined graphics package. Allows the incorporation of other geostatistical programs, such as GEO-EAS.
Geostatistical Toolbox Platforms: Shareware - DOS The Geostatistical Toolbox is a fully integrated environment for the analysis of spatially correlated data. Univariate and bivariate statistics, 2D and 3D variograms, ordinary and simple kriging, 2D and 3D co-kriging, Menu driven, context-sensitive help, spreadsheet for data entry and editing included. Manual in ASCII and Word Perfect included on disk. Source code available from the author to individuals for their own research.
GSLIB Platforms: Freeware - DOS, UNIX Geostatistical Software Library written in Fortran by Clayton V. Deutsch and Andre G. Journel. The programs include 2D and 3D variogram modeling, all types of kriging, 2D and 3D simulation, and a collection of utility programs, including cell declustering and descriptive statistics. Easy exchanges of data with Geo-EAS. Input files are all Geo-EAS type ASCII files. Outputs of grids are in row major order and are readily transferable into ARC/INFO. The associated book Geostatistical Software Library and User's Guide by Deutsch & Journel, Oxford University Press 1992, includes disks containing Fortran source code for all of the programs with compiling instructions for PC and UNIX.

ISIM3D Platforms: Public domain - DOS A 3D multiple indicator conditional simulation program for the generation of realizations from random functions with a non-Gaussian bi-variate distribution.
Natural Neighbor Platforms: Public domain - DOS Natural neighbor interpolation is a weighted average method where the weights are area-based. This automatically allows the correct compensation for irregular configurations of data. The interpolation subset is the data which are natural neighbors of the interpolation point. The resulting surface is analogous to a taut rubber sheet stretched to meet all the data.
UNCERT Platforms: Freeware - UNIX, IBM RS6000, SGI, SUN, Solaris, HP, SCO, and Linux UNCERT is a public domain uncertainty analysis and geostatistical software package. It was developed for evaluating the inherent uncertainty in describing subsurface geology, hydraulic properties, and the migration of hazardous contaminants in groundwater flow systems. The package is well suited for evaluating hazardous waste sites and evaluating remediation methods, but the package also has many general modules which are usable by researchers from a wide range of disciplines. The modules included are: Array: An utility for performing mathematical operations on one, two, or a series of 2D or 3D grids. Block: A visualization package for viewing 3D scattered data and 3D finite-difference (block/rectangular) grids. Block can also do rough volume calculations. Contour: A 2D contouring and gradient analysis package. Grid: A 2D and 3D gridding program. Inverse-Distance, Simple and Ordinary Kriging, and Trend-Surface Analysis are supported. Histo: A utility for doing univariate statistics. Histogram, Box and Whisker Plots, and Probability Plots are supported. Mainmenu: A simple menu interface to select the other UNCERT modules. Modmain: A GUI pre- and post-processor for MODFLOW. MT3Dmain: A GUI pre- and post-processor for MT3D. Plotgraph: A X-Y graph utility. Regression also supported. Sisim: A GUI pre- and post-processor for a Soft Indicator Kriging Simulator. Surface: A 2.5D visualization tool for viewing 2D grids as a surface. Color contouring, shaded relief, and gradient viewing options available. Vario: A tool to generate experimental semivariograms (1D and 2D) for irregularly scattered data, and gridded data. Variofit: A tool for modeling experimental semivariograms. All the program modules use a Graphical User Interface (GUI) with pull-down menus, pop-up dialogues, and when appropriate graphic windows. The UNCERT User's Manual is on-line and downloadable.
Variowin Platforms: Freeware - Win3x VARIOWIN 2.1 is a collection of three Windows programs that are used for Spatial Data Analysis and Variogram Modeling in 2D. An extensive on line Help covering basic geostatistical concepts is also included. PREVAR2D builds a Pair Comparison File, i.e. a binary file containing the pairs of data sorted by increasing distance. Pair Comparison Files can be built from subsets in order to reduce memory requirements. VARIO2DP is used for Spatial Data Analysis of 2D data. It uses an ASCII data file and a binary Pair Comparison File produced by PREVAR2D. Features implemented in VARIO2DP include; Possibility to characterize the spatial continuity of one variable or the joined spatial continuity of two variables; Variogram surfaces for identifying directions of anisotropies; Directional variograms calculated along any direction; Several measures of spatial continuity. Not only the Semivariogram but also the Standardized Semivariogram, the Non Ergodic Covariance, the Non Ergodic Correlogram and the Semimadogram are used to measure spatial continuity; H-scatterplots to assess the meaning of these measures; Identification and localization of pairs of data adversely affecting the measure of spatial continuity. Once identified, these pairs can interactively be masked from the calculation; Variogram clouds for identifying pairs of data values having the most influence on the measure of spatial continuity. Those pairs can also be located on the sample map; Possibility to save directional variograms in an ASCII file which can be used for subsequent modeling by MODEL. MODEL is used to produce a 2D general model of spatial continuity in an interactive way. Several directional variograms read from a variogram file produced by VARIO2DP are adjusted simultaneously by a 2D nested model. Adjustment is done with scroll bars and each time a parameter of the model is changed, the model is recalculated and redrawn on the directional variograms used for the fitting procedure. The 2D model can be saved in a model file which can be used for kriging or for geostatistical simulations by other public domain geostatistical packages (e.g. Geo-EAS, GSLIB).
