That is not what verifiability is about. Climate and Vegetation characteristics are generally continuously changing properties and the specific zone limits defined by some convention are not usually verifiable in the field. In case of climate zones you would for example need long term measurements at a certain place to determine if it belongs to a certain climate zone and even if you have that you cannot say anything about the climate of other locations - hence you cannot draw a boundary in a verifiable way. I explained this in case of deserts (probably the most prominent attempt to map something like this in OSM) some time ago in http://wiki.openstreetmap.org/wiki/Talk:Tag:natural%3Ddesert -- Christoph Hormann http://www.imagico.de/ _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
