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.

GS+ works for you

GS+ is geostatistics, which provides a way to better understand the autocorrelation inherent in spatial data – and to use this knowledge to create optimal, unbiased maps with known error.

GS+ provides easy access to these computationally intensive analyses. Whether you are analyzing oil deposits, plankton distributions, sun spot patterns, infectious disease outbreaks, or soil resources, GS+ provides ready access to the power of geostatistics.

  • Powerful variogram models with full user control
  • Fast kriging and conditional simulation
  • Customized maps, easily exported
  • Over 1 million input records

GS+ Features

GS+ is a one-stop shop for geostatistical analysis, with an easy-to-understand user interface and default values for all analyses easily changed and tested.

New in GS+ 10

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

Semivariance Analysis – Variograms and Semivariograms

GS+ provides both isotropic and anisotropic variograms, with full control over separation intervals – use constant interval classes or use different breakpoints for every lag class. Target specific anisotropic directions and scale values to overall sample variance.

  • Variogram surface maps to assess Anisotropy
  • Dynamic variogram modelling
  • Variance cloud analysis
  • h-Scattergram analysis
  • Easily identify and remove true outliers

Comprehensive Interpolation Tools

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

Multiple Autocorrelation Measures

In addition to semivariance analysis, GS+ offers isotropic and anisotropic (direction-dependent) measures of autocorrelation to fit every analysis need:

  • Drift
  • Correlograms and Covariograms
  • Moran’s I
  • Fractal Dimensions
  • Standardized and Relative Variograms
  • Madograms and Rodograms

Data Central

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

GS+ produces 2D and 3D surface maps of 2D data and 1D maps of transect or time-series data. Display maps with different contouring schemes, rotate 3D maps on the fly and zoom into maps to view more closely. Co-display original sample locations, and visualize estimation error.

  • Quickly map primary data and estimation error
  • Specify contour intervals and colours
  • Include postings on map surfaces
  • Define exclusive or inclusive polygons
