Hyperlocal news mapping site Everyblock has launched in two new cities in the US.

Charlotte and Philadelphia join Chicago, New York and San Francisco as cities mapped by the site.

Adrian Holovaty, founder of local crime news site chicagocrime.org, launched Everyblock at the start of the year as a destination where users could search for civic information and news items by address, postcode or neighbourhood on an interactive map.

Holovaty started the site with a £550,000 grant awarded by last year’s Knight News Challenge competition.

In addition to the public information already found on the city maps the new sites will add extra layers of content.

The Charlotte map will include library information, updating listings with new titles available locally and chart all local 911 calls to the police and ‘significant police events’ in the city.

The location of series crimes will charted on the Philadelphia map along with areas mentioned by the local authority’s Streets and Services agenda bodies.

Any area of Charlotte mentioned in city council meeting minutes or zoning minutes will be charted on that map.

“We’re analyzing the text of these meeting minutes/agendas for all locations referenced therein,” wrote Holovaty.

“If the city council or rules committee mentions something near you, you’ll see it on your EveryBlock page.”
