Crowdsourcing Neighborhoods

Search for a place

Zetashapes is an experiment in crowdsourced US neighborhood polygons. From here, you can download neighborhood boundaries for every city in the US derived from geotags on flickr photos. You can also edit these boundaries and download custom GeoJSON with your edits applied. Your edits will also be contributed back into improving the overall boundaries.
