MapQuest's recent entree into mobile developer tools is an interesting one. Choosing Android over iPhone means going toe to toe with Google, a familiar competitor to MapQuest on the mapping front. Mapping is logically MapQuest's turf. The company was helping people find directions online before Larry and Sergey were even in graduate school, let alone leaving to found Google. Of course, another way of looking at it is that Android is in line with MapQuest's latest push to open up mapping data.
MapQuest is known for driving directions. Now it hopes to bring those to mobile navigation systems everywhere. Today the company has launched the MapQuest Open Guidance API built on top of OpenStreetMap. Developers will now be able to include turn-by-turn directions in mobile apps without any usage limits being imposed by MapQuest.
You'd hardly notice the difference unless you were looking for it. MapQuest's latest API is a reinvention of its MapQuest API to display maps. So, what's new? Following the company's recent pattern, MapQuest Open API is based on OpenStreetMaps, the crowd-sourced map favored by many modern geo-hackers.
