Neighbourhoods auto detection for big cities

[virtser]

What if we have city neighbourhood polygons for Tel-Aviv, Jerusalem and Haifa?

When landlord submits apartment, we don't have to ask for neighbourhood, we can detect its geo location by city + street name, and detect its neighbourhood by finding the right polygon for geo location.

The neighbourhoods information is mostly important for Search and Smart Search.

The question is where can we take that neighbourhood polygons information?

Madlan got it, can we steal it? https://www.madlan.co.il/local/%D7%AA%D7%9C%20%D7%90%D7%91%D7%99%D7%91%20%D7%99%D7%A4%D7%95#mdlnPriceIndexAnchor

There are not so many neighborhoods and geolocation data like this is not big, We should keep the polygon in the Neighborhoods DB table. It's possible to find a geolocation POINT in a geolocation POLYGON both in Javascript and in SQL.
