Variogram / Semivariogram Surface Maps – Identify anisotropic semivariance quickly and accurately. Maps of semivariance in every compass direction (the center marks the origin of each variogram / semivariogram) allow the axis of maximum variation to be easily identified.
Variance Cloud Analysis provides a graph of variance vs. separation distance for every pair of points that make up a specific lag class in a variogram / semivariogram. This allows outlying pairs to be quickly identified and edited as needed.
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.
创建变异函数
GS+使您可以完全控制变差函数参数,如主动滞后距离和个体滞后类的大小。默认值提供了合理的起点,您可以优化分析以适应特定的数据集。
自动创建变差函数模型---可以自动创建kriging模型,大程度地使用迭代技术来优化您的数据,以优化良好的模型拟合。模型窗口允许您覆盖GS+选择的值,滑动条控件允许您立即看到更改的结果。GS+为几乎所有的kriging应用程序提供足够的模型。
由于数据异常,变差函数有时是不规则的---当它们是的值时,它们就会变得很明显,而不是与其他值在特定的范围内自动关联。GS+提供了h散射图和方差云分析,使您能够快速地可视化和识别异常值,并且新的掩饰命令允许您像手术一样移除(暂时或地)违规数据记录。定向变异(各向)函数是同时产生的各向同性的变量,所以您可以很*地评估自相关是否依赖于罗盘的方向。例如,当存在一个斜率效应或其他环境特征时,在一个方向上的自相关与另一个方向的自相关是不同的。
But don't take our word for it
Take the word of the hundreds of scientists and engineers who have cited GS+ in their research publications – over 100 in 2019 alone. Or the hundreds of users at universities, government and non-governmental research institutes, and various industries in almost every country in the world.
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.
