My thinking was that a relief map simulates the appearance of topographic relief through the use of ‘hill shading’ (to use the ESRI term).
You can “shade” the relief map made with r.relief or other psuedo relief maps, like an aspect map (can you shade a slope map in this way? Not sure what it would tell you visually) with a color map of some kind (hence r.shaded.relief). Or you can “drape” the color map over the relief map—perhaps “r.color.drape”. There are other kinds of image fusion for sure. The goal is to use names that users can easily understand. If d.shade can shade something other than a relief map of some kind, then perhaps d.shade is best. If it mainly is for shading relief maps maps, d.shaded.relief might be better.

I don't think this would be a good idea. r.relief (former r.shaded.relief) creates "shade from the (terrain) relief". r.shade (former r.shadedmap, and d.shade) allows to "put the shade on a colored/colorful raster" where both shade and raster can be anything. Shade can be e.g. aspect, slope or shade derived from the relief. I know this is probably clear but his was my thinking. I didn't though about r.shade and r.relief names before you suggested them and I'm not 100% satisfied with r.relief because it is in fact not relief but shade from relief. However, I like the new names because they are short, there is no problem with using or not using the dot between words and they are distinct from each other. Michael ____________________ C.

So, if you like it, I can like it too and I will change it hopefully soon. Just to be sure: including r.shaded.relief -> r.relief? r.shaded.relief -> r.relief r.shadedmap -> r.shade d.shadedmap -> d.shade Done in r63305 with few other improvements. Now I'm not sure with [rd].shade parameters. reliefmap and drapemap are not particularly explanatory. My idea was shade and color which is better when shade=slope compared to relief=slope. color=elevation is also quite understandable but of course it is quite unexpected that the color option is a raster map. There is also one detail I'm not sure about. r.relief might be now missing one keyword and that is "shaded relief". "relief" should be there too but having also "shaded relief" distinguishes it from things like "local relief (model)". http://trac.osgeo.org/grass/changeset/63305 Vaclav Markus _______________________________________________ grass-dev mailing list grass-dev@lists.osgeo.org<mailto:grass-dev@lists.osgeo.org> http://lists.osgeo.org/mailman/listinfo/grass-dev
