I think it would be better to describe the flood by a height, rather than by a date. This way, it is generalisable to future floods. Something like: flood_prone=yes flood_prone:height=* Obviously, we'd need to carefully define "height" (is it normally with respect to some marker, or with respect to sea level, etc.?) Anyway, the idea is that this field would describe under what conditions the area (or way) is flood prone. _______________________________________________ Talk-au mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-au
