Hello. I have used r.slope.aspect to generate a raster map of
slopes. The map has labeled each point with slope in degrees.
I would like to get slope as the tangent of the degrees. I used
r.mapcalc, and used the equation:
tan.0 = tan(@slope.0)
where tan.0 is my output map and slope.0 is the raster map with
slopes. However, I get tangent values equal to either zero or
one, and no fractional values. Can anyone help?
