GS+ is a comprehensive geostatistics program that is fast,
efficient, and easy to use. GS+ provides all
geostatistics components, from semivariance 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.
What is geostatistics? Geostatistics is a class of statistical
techniques developed to analyze and predict values of a variable distributed
in space or time. It begins with a type of autocorrelation analysis
called variography or semivariance analysis, in which the degree of
self-similarity is displayed as a variogram. The variogram model is
used to predict unsampled locations by kriging or conditional simulation,
which produces estimates of the variable across the entire spatial or
temporal domain.
GS+ was first introduced in 1988. Geostatistics is not an
add-on feature of GS+ – it is at 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, especially for
exploring geostatistical relationships within data sets. 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 for those users who are
not working with other mapping programs.
GS+ is compatible with modern Windows platforms (see
System Requirements) and accepts data
files with as many as 2 billion records. Algorithms are fast and
dependable. Geostatistical analysis is computationally intensive
– prior to 1988 most analyses had to be performed
on supercomputers, but GS+ allows the Windows environment to
handle most data sets with ease. Written in a combination of Visual
Studio and Fortran, and drawing on GSLIB subroutines, GS+ shows
that computation speed, flexibility, and an intuitive interface are
compatible.
Many scientists, engineers, and students worldwide are using GS+.
