I often add LiDAR data to a map along with a shaded relief. Most of the time I have to generalize the LiDAR DEM depending on the scale of the map. Still, there is often too much detail and mountain ridges and valleys are not well pronounced.
I came across an article recently that describes the process of combining 2 hillshade models, one detailed and the other generalized. The resulting relief is very nice. I would like to produce such effect in my maps: assuming I have 2 hillshade (detailed and generalized) rasters, what is the best way of combining them to achieve such effect?
