Instructions provided describe how to change the number of points used in a semivariogram. By default, the semivariogram/covariance tools work with data sets having a maximum of 300 data points. This value was selected for performance and usability reasons. However, if it is necessary to increase the maximum number for a large data set, the following instructions demonstrate how to do this. An increase to this maximum value may may cause slower performance.
If using a version other than ArcGIS 9.x, use the operating system’s search utility to find the file named AdvancedArcMapSettings.exe.
