Variography Tutorial

This tutorial will guide you through some ways to explore your data by creating variogram models.  To start, you will need to load the Variography.spt project from the Tutorial files.  

Open SpaceStat and choose File -> Open project

Navigate to the location of the Tutorials files.  The default location for these files is: C:\Program Files\Biomedware\SpaceStat\Tutorials

If you installed your copy of SpaceStat in a different location, the Tutorial folder will be wherever SpaceStat is installed.  

Go to the Kriging folder and select the Variography.spt project.  You will see a point geography named NE_sample and many datasets such as MERCURY, TOLUENE, and LOG_LEAD.  

Launch the variogram model dialog

The variogram model view by default appears at the bottom of the Data view panel.  If the variogram model view is not visible, you can show it via the 'Window' menu, by choosing 'Spatial weights and variogram model view'.

Left click the 'variogram models' Tab to view the list of variogram models available for each geography. The list is empty at the beginning.

Right click a geography (i.e. NE_sample), and select the option 'Define new variogram model'.  The variogram model dialog appears.  

You can also access this dialog by going to the Tools menu and selecting 'Create variogram model'.  A submenu will hold any valid geographies from which you may choose a dataset to for your variogram model.
