   Great minds think alike! I used the tree inventory to try to map out the
spread of the Emerald Ash Borer, after our lovely Ash at home had to go
under the axe.


   Did you get much help from the city? I sent them a few e-mails (and
contacted Open Data Ottawa) and got zero feedback, so I shelved the
"public" version of my app until I was sure I could rely on the data.
