IMHO your picks are totally arbitary, I fail to see any logic behind what you consider geographical feature and what not? I think that ruling "sand" and "bare_rock" out is because languages (might?) lack a word to describe it with a "better" word that wouldn't mention the surface itself. Therefore such geographical features are referred using the particular surface. I suspect that ruling water out is because it's not called "lake" or so in osm key string? -- i. _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
