+0.8 I would also like to see building parts, but I think that another option instead of drawing another way for the "whole building" would be to group those parts with a relation. > Yes, it could be a good idea to invent a separate tag for building parts. > I would appreciate that (and initially these issues are part of the reason > why my proposal is not a proposed tagging scheme in the common sense of the > proposal process). > But one question is left here: > What is the building outline you would like to map in future as > building=yes, too? > Is it (a) the "maximum size outline" as shown in aerial imagery? yes, I guess that's an easy to map approach that would suit well > Is it (b) the "on-ground-outline" a pedestrian would be able to go along? no, this would in some cases be ridiculous (think of a "mushroom"-building: the most parts would miss). If this is required (in some cases there is indeed a huge benefit) I would use another tag. > Is it (c) the "maximum size outline" including underground parts not build > up above ground - like bigger underground parking areas? No, I would not extend this to underground parts (they would get their own tagging and ways if necessary). Showing underground in a standard map will be very confusing, because they will not be recognizable on the ground and hence create a different shape in respect to what people are used to see on the ground. (They are more confusing then helpful). > Is (d) the building=yes a fallback for renderers not supporting the > building_parts? could be interpreted as such. Could also be a reduction for lower zoom levels and renderings that focus less on building detail Cheers, Martin _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
