DESCRIPTION

r.colors.stddev set raster map color rules based on standard deviations from a map’s mean
value, either as a continuous color gradient or in color bands per standard deviation
(S.D.) from the mean.

With the color band option values less that 1 S.D. from the mean are colored green, within
1-2 S.D. are colored yellow, within 2-3 S.D. are colored red, and beyond 3 S.D. are
colored black.

For a differences map there is an option to lock the center of the color table at zero.
Values more than two S.D. below the mean will be colored blue; values below the mean but
less than 2 S.D. away will transition to white, and above the mean the colors will
simularly transition to full red at +2 S.D.

EXAMPLE

North Carolina sample dataset location:
g.region raster=elevation -p
