I fixed the "park"; indeed it is not really a park, because people cannot go inside it for a walk.

The tree is already defined as "Platanus acerifolia", which seems to match the description.  It has a large circumference than your figure; this comes from a 2014 import of UrbIS data about trees.

We’ll be happy to update the data but it’s easier if you can provide a reliable data source, otherwise it would be hard to justify if someone complains we mistakenly broke correct data.

Thanks for this.
