<div dir="ltr">I agree with the advantage of polygons when performing queries of the type 'show me all bakeries in this neighborhood'. This will however only work if that neighborhood is clearly defined in terms of boundaries. If we agree that this is not the case, we are just going to be creating confusion and perhaps even edit wars when we settle on polygons for neighborhoods. A node location for a neighborhood is something locals should be able to relatively easily agree on. I think we can see much faster progress proceeding along that avenue.<div>
<br></div><div style>I think that we should show great restraint with importing any more boundary polygons. They make mapping more difficult and confusing, for example because they often overlap with roads. They do not represent surveyable / verifiable data in many cases, which makes for dead data, which we have enough of in the US.</div>
<div style><br></div><div style>Back to my original question, rephrased slightly - would there be a legal impediment to use Zillow or Geonames data to derive neighborhood point data to increase coverage in OSM?</div><div style>
<br></div><div style>Why I care - because neighborhood data represents just what makes OSM unique - local knowledge. Why use external sources then you say? Well, the point would be to make it easy for locals to add neighborhood data to OSM, by offering a data starting point. <br>

<div></div></div></blockquote></div><br></div>I agree that most neighborhood boundaries are subjective. Of the cities I've lived in, some neighborhoods are clearly define, usually by natural or man made artifacts, others are definitely fluid. When importing addresses into Seattle we considered adding a neighborhood tag to each address or building node but decided against it. Administrative boundaries seemed like a better plan. After this discussion I'm not longer so certain.</div>
