Note In deciding whether to save colour inflection points by value or by percentile, use the
following guidelines. If it is more important to assign specific colours to specific values in a
series of related grid files, then save by value. If it is more important to assign a particular
colour range to a series of related grid files where the value range may vary considerably,
then save by percentile.
Exploring the Relief Shading Properties Dialog Box
The Relief Shading Properties dialog box controls the basic elements of grey level adjustment using
a Hue/Saturation/Luminescence (HSL) colour model. Grids can be viewed in grey-scale only when
relief shading has been applied.
The Azimuth box enables you to set the direction (in degrees) from which the imaginary light source
emanates.
The Inclination box enables you to set the angle of incidence (in degrees) of the imaginary light
source measured from a horizontal plane. The effect of using different values depends upon the
general “topography” of the grid surface.
