GS+ Rodograms
Rodograms are similar to traditional
variograms except that the square root of
the difference between values at different sample locations is used
rather than the square of the difference as for traditional
semivariance. Different anisotropic directions appear on separate tabs.
Parameters for calculating rodograms are set in the
Autocorrelation Window.
When the program is running, placing the mouse cursor over a rodogram point will produce a box
showing the number of pairs in that lag class interval, and clicking on the point will
produce a Variance Cloud or
h-Scattergram graph of all pairs in that
interval. Other measures of autocorrelation provided by GS+
include variograms,
correlograms,
madograms,
covariograms,
drift,
Moran’s I,
fractal dimension, and
standardized,
general relative, and
pairwise relative
variograms.
