@ame @openstreetmap Everyone does. As a mapper it's important to work out what is feasible to keep up-to-date. By all means micromap all the detail for a small area to try it out : you soon learn what works personally.
#iNaturalist does provide for mapping cultivated plants, but those records don't get the same attention for verification as others. That is the approach I've used.
@ame @openstreetmap It's quite hard to keep up with trees which may last longer than many buildings (went looking for one yesterday which has gone), but planting gets rearranged all the time in botanical gardens, especially those still used for teaching and research. Somewhere like Tartu would be an absolute nightmare both to map and maintain without that factor.
@ame @openstreetmap Some thoights about mapping hotanical gardens from 13 years ago http://sk53-osm.blogspot.com/2013/09/a-quartet-of-botanical-gardens.html.
I'd be cautious about mapping small plants such as herbs even in a botanical garden. Beds get swapped around for all sorts of reasons, but the actual dedicated bed tends to remain and I think that is the sensible base unit. There is a tag landuse=flowerbed for this, but I regard the use of the landuse key as unfortunate.
@oliver @openstreetmap In addition to an update frequency of weekly at best, I have no idea if those #OpenStreetMap tags are actually used by #OpenCycleMap compared with more explicit ones. Best ask @gravitystorm himself (creator of OCM)
