I totally agree (besides to the "wrong", because I never said I'd make the curb the border, usually I'd use the fence (if any, mostly there are in here) for this. Anyway: it is clearly an approximation, and we can always improve this in the future. > There is not necessarily a direct connection between landuse and > zoning. yes, landuse is about the actual landuse, zoning is about the legally permitted landuse. > Is a home-based daycare residential or commercial, or > commercial / residential. (Or residential commercial=permissive) guess "home-based" is quite clear. > What about a home-based medical practice or barber shop? I find it perfectly acceptable to have local shops or other home-based businesses (e.g. often there is "insurance agencies" which are operated out of normal detached houses) inside a residential area/landuse/zone, so even a not-home-based barber-shop or convenience shop might be landuse=residential (the wiki speaks of "predominantly"). For further detail it might indeed be possible in the future to refine "residential" into different subtypes (e.g. the German law knows of 3-4 different types of "residential" plus some mixed ones, and while I am not suggesting to map according the German law this could be taken as a hint that more detail is not necessarily an exxageration). > Locally, zoning is only directly observable when an application for a > zoning change requires a posted sign.

If someone wanted to map the zoning (with appropriate tags, not "landuse"), this would be OK. The data is publicly available (that's on the other hand an argument not to map it in OSM). cheers, Martin _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
