GS+ was introduced in 1988 as the first integrated geostatistics program for PCs and workstations. It quickly became the geostatistics program of choice for users worldwide. Widely praised, GS+ was the first geostatistics package to offer all components – from semivariance analysis through kriging and mapping – in a complete package.

Today GS+ remains the leading 2D geostatistical software for the earth and environmental sciences. It is used worldwide by industry, government agencies, and academic researchers, and has been cited in over 1000 scientific articles.

Version 10 offers additional interpolation options, rapid validation of variogram models, and a way to subsample huge data sets to improve analysis efficiency.

• New Kriging options – Ordinary, Simple, and Indicator Kriging
• Test alternative variogram models with Jackknife and Cross-Validation analyses
• Subsample big data sets for autocorrelation analyses
• Improved graph options and faster interpolations

GS+ provides comprehensive interpolation options – different types of Kriging, Conditional Simulation, and conventional Inverse Distance Weighting. Define nested polygons to map within or to exclude from mapping. Output can be mapped in GS+ or output files can be input to ArcView®, Surfer®, or other mapping and GIS platforms.

• Multiple Kriging methods (Simple, Ordinary, Indicator, and Co-kriging)
• Uncertainty analysis – compute variance maps
• Cross Validation analysis tests your interpolation system

The Data Worksheet holds sample data – x and y coordinate locations together with sample IDs and up to 60 data values per location. Data can be imported from a variety of sources including spreadsheets, databases, and text files. Missing values are handled gracefully, and data values can be individually deleted or turned off or on.

• View and transform the active data set
• Import over a million input records
• Apply lognormal and other transformations
• Easily identify and remove true outliers
