About Basing Colors on Values from the Current View
Calculating colors based on values from the current view uses the minimum
and maximum elevations within the current view or extent of the map.
This option yields a much more applicable result than the Project
option where
outliers are able to
skew
the distribution of the colors. The Current View option can reduce
the effect of skew in the distribution of elevation values even further
by using the
standard deviation to
determine the minimum and maximum values.
