Geostatistics for the Environmental Sciences

What is geostatistics?

  • Geostatistics is a class of statistical techniques developed to analyze and predict spatial values of a property. It begins with a type of autocorrelation analysis called variography or semivariance analysis, in which the degree of spatial self-similarity is displayed as a variogram. A curve is fit to the variogram, and the equation that describes the curve - called the variogram model - is used to predict unsampled locations by kriging or conditional simulation. This produces optimal unbiased estimates of the property across the entire spatial domain. The same analysis can also be performed with one-dimensional data such as time, for example hourly or daily measures of some property, to provide optimal interpolations and error terms along a time line.

GS+ is the best 2D geostatistics software available

  • GS+ is a comprehensive geostatistics program that is fast, efficient, and easy to use. GS+ provides all geostatistics components, from variogram analysis through kriging and mapping, in a single integrated program widely praised for its flexibility and friendly interface. Many users are surprised that geostatistical analysis can be so easy and intuitive.

 

But don't take our word for it

 

GS+ means geostatistics

  • Geostatistics is not an add-on feature of GS+ – it is the heart of the software. Many of our users have access to other geostatistics tools within their favorite GIS or mapping programs, but come to GS+ for their serious geostatistical analyses. Because GS+ output is compatible with industry standards, GS+ can be used directly with many of these other programs. Or it can be used standalone – GS+ has its own data worksheet (which also accepts Excel, Access, and other types of data files) and produces its own maps.

About Gamma Design Software, LLC

  • Gamma Design Software was started in 1988 to bring geostatistics to Windows workstations and desktop computers. At that time fast geostatistics software was available only for supercomputers, and other users needed to compile FORTRAN source code on their own. Since then, Gamma Design has been a world leader in providing accessible, powerful, and easy-to-learn geostatistics software for the evolving Windows environment.
