Yahoo has been using Nokia’s HERE Maps data for its mapping services. Seems, they have now absorbed indoor maps data as well from HERE. Yahoo has now integrated full venue maps for places like shopping malls, travel interchanges and sports stadiums. You can check enhanced Yahoo maps by clicking maps.yahoo.com.
You may know that like outdoor mapping, HERE Maps is the pioneer and leader in indoor mapping as well, which it calls “Venue Maps”. While on average a person is claimed to spend 90 per cent of their time indoors, HERE’s mapping of venues now stand at 50,000 buildings, with many more being added on a regular basis.
