In maps (as inward life) boundaries tin hold upward fluid entities. This seems especially truthful when considering local neighborhood boundaries, where it tin hold upward real hard to honor fifty-fifty ii people who grip on the borders of their local neighborhoods.

In Los Angeles the boundary of the city's Eastside neighborhood is peculiarly hard to define because in that place seems to hold upward no official map of the area's extent. The Los Angeles Times hence decided to settle the declaration past times quest their readers to depict Eastside on a map.

On the L.A.'s Eastside: Where exercise you lot depict the line? map you lot tin role the Leaflet drawing tools to depict your thought of where Eastside's boundaries lie. You tin so compare your concept of the neighborhood amongst the catch of the Los Angleles Times too amongst the views of other readers.


Bostonography was in all probability the get-go website to endeavor too crowdsource neighborhood boundaries, amongst their projection to honor out where residents believe Boston's neighborhood boundaries lie.

The projection uses a Google Maps tool to allow participants to depict on a Google Map where they mean value Boston neighborhood boundaries run. This has allowed Bostonography to exercise a map of all the amalgamated responses so far.

The results for each neighborhood are also beingness analysed to run into which neighborhood boundaries participants accept a potent understanding well-nigh too to highlight areas where in that place are contradictory opinions well-nigh which neighborhood they belong to.
