@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.
@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)
