Andre, Do you have a copy of Vertical Mapper?
If you do, get a hold of a DEM of the area that you want to look at. If it is larger than a quad sheet, it would be benificial to merge the DEMs into one raster to speed processing and make a smooth transition in elevation coloring. Now the next step is fairly simply, simply click on the colour button in the vertical mapper window when you have your raster image highlighted. This brings up the window to adjust the colour profile of the raster. At the bottom left of the window is a check box for Relief shading. Check this and then select the properties. From here you can adjust the height of you light source and the direction from which it shines. It is good to experiment with different directions, brightness, and contrast to ensure that you have maximum visiablity of the areas that are most important to you. Another way to preform this function is through the aspect function of Vertical Mapper but it does not make as smooth of a color scheme. Cheers! Josh C.

One occasionally sees maps that do have this type of shading and I'd like to experiment with it in my maps. I do include elevation countours, but would like to see what the effect would be by adding relief shading. Does one need a DEM of the map area, or is there a way to do the necessary calculations from the positions and elevation values of the contours? TIA.
