Just hours after Apple confirmed that it had purchased Locationary comes word that they have agreed to buy yet another mapping service. Bloomberg is reporting that Cupertino is buying online transit-navigation service HopStop.com Inc. The service offers users in 500 cities the fastest way to travel by foot, bike, subway, and car, all in real-time.

HopStop, based in New York, provides directions for more than 140 major metropolitan areas in the U.S. and six other countries, according to its website. Locationary, by contrast, has been called the “Wikipedia for local business listings.” It uses crowdsourcing and a platform called Saturn to provide real-time information for places around the world.

As AllThingsD noted earlier:

Not only does Locationary ensure that business listing data is positionally accurate (IE: the restaurant I searched for is where Apple said it would be), it ensures that it is temporally accurate as well (IE: the restaurant I searched for is still open for business and not closed for renovation or shuttered entirely).

It will be interesting to see what Locationary and HopStop bring to future versions of Maps for iOS and OS X.

The free HopStop is available in the App Store for the iPhone/iPod touch and iPad.
