r.hypso produces the hypsometric and hypsographic curve
related to a digital elevation model and prints the percentiles.
The
hypsographic curve gives the distribution of surfaces in
different altitude ranges. Each point on the function reports on the
y-axis the elevation and on the x-axis the portion of the basin
surface placed above such elevation value. The
hypsometric curve
uses adimensional axes.
-a: generates hypsometric curve
-b: generates hyposographic curve
r.hypso -b map=elevation image=/tmp/hypso
generates hypsographic curve, and
r.hypso -a map=elevation image=/tmp/hypso
generates hypsometric curve.
