</span>That is a good start, if you could beef up this table with the<br>
leaf_type/leaf_cycle and genus tags that would be what i had in mind.<br>
Both creating this and verifying that this is actually consistent in<br>
the data can be done with a simple GROUP BY query on the data.<br>

</span>You probably misunderstood me then - i was not questioning the accuracy<br>
of the data (although with a survey date of 2013 there are probably<br>
some trees removed for building stuff in the meantime), i was worried<br>
about mismatches with the existing data in OSM. It is quite possible<br>
that resolving those usually needs to modify the existing data rather<br>
than the trees but you should have a solid plan for handling this kind<br>
of problem. Just dumping the data and hoping that mappers will sort<br>
out problems later is not the way to go.<br>
