23621	[patch] Check for trees that are too big	anonymous	team	"According to the Guinness World Records, the greatest circumference for a tree is 43m. I suggest implementing a check for trees with circumferences exceeding this value, as they are likely to be errors.

For instance, we currently have 2001 nodes in the database with a circumference of 45: https://overpass-turbo.eu/s/1JUU. Osmose could suggest to check them and:

1. delete the value if plainly wrong or
2. fix 'circumference=45' to 'circumference=0.45' or 'circumference=45 cm'

Another check could be on height. Trees taller than Hyperion (tallest tree in the world with 116m) are likely to be errors.

[https://github.com/osm-fr/osmose-backend/issues/2200 I suggested this check in Osmose] and they redirect me here:


''https://overpass-turbo.eu/s/1JWd
At least 62638 trees worldwide affected by the circumference limit of 43m (excluding those with units or decimals).

I suspect this might be interesting for JOSM, for their numerical validation rules (which we synchronize with Osmose). That way it benefits more people and people who add those trees get a warning prior to uploading it in the first place.''"	enhancement	closed	normal	24.07	Core validator		fixed	natural tree size
