Thanks Joost, It's always good to see such graphs. I'm interested to learn
* What are we mapping now ? * What did we map in the past ? * Who is mapping what ? * Who is mapping similar things as me ? (Or am I the only one mapping feature X ? / can I ask someone also for help with feature X ?) * Where are we mapping feature X (on town/village level) ? With "what" I mean e.g. categories of features: streets (highway tags), landuse/landcover, boundaries, buildings, shops, etc. However, for some purposes categories might be broken. mapping amenity=library or amenity=bench are quite different. The same holds for tourism=hotel and tourism=information,information=board. The library and hotel are "important" features, bench or an information board not so. I know "important" is relative, but I hope you understand what I mean. Of course this is harder when we start thinking about "attributes": turn lanes, destinations, house numbers, or additional attributes for amenity=bicycle_parking (such as covered or bicycle_parking=...), etc. For the last two questions (mapping feature X) the ultimate goal would be to answer questions such as "Who else is mapping bicycle_parkings ?" With which attributes. ? Where is feature X not mapped at all ?
