Description

r.blend blends color components of 2 raster maps by a specified percentage of the first map.

Example

       Blending the aspect map with the elevation map for a shaded map (North Carolina sample dataset):
       g.region raster=elevation
       r.relief input=elevation output=relief zscale=10
       r.blend -c first=elevation second=relief output=blend percent=75
       Figure:Elevationblendedwithshadedrelief

Keywords
