[Talk-us] administrative boundaries and Nominatim

So I transferred the attributes from the middlesex node to the relation and deleted the node, lets see how this works.

If I was to complain about one thing nominatim related it would be the documentation.  While I was able to find some pretty detailed info for installing it, but less about how it worked.

The answer is "If you see bad data, replace it with good data".

It's also useful to think of Nominatim as a data product, like a rendering. Some things are due to bad rendering and some things are due to bad data.

One of the things that's nice about Nominatim is that it gives you that detail page where it explains how it derives its answers. That gives you the opportunity to fix the data, and if it comes to it, send useful feedback to the Nominatim developers.

I realize my email in the other thread could come off as complaining about Nominatim- I'm not. I'm mostly complaining about the poor data quality of New York City in OpenStreetMap in hopes that we'll be able to address it.
