Rather than plant_type=orange_tree or similar, I think it would make more sense to tag plants and trees with the scientific (Latin) name of their species or hybrid. These are already standardized and the local language translations ('citrus x sinensis' => 'en:orange', 'es:naranja') are also standard, and can be looked up by the map renderer rather than duplicated for every orange tree on the map.
I don't expect individual plants will be tagged very often (even the Germans have not added the 'unter den' linden trees) but for managed forests and perhaps farmland it might be useful. Further, following the OSM guidelines on verifiability, instead of making new classification rules for tree / bush / shrub / whatever, just tag the size of the plant in metres. Of course this doesn't cover the tagging of pots; as far as I am aware there is no existing categorization for those :-p. -- Ed Avis <e...@waniasset.com> _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
