Indoor map system provider Point Inside has begun its promised global roll-out of maps for airports outside of North America.
The service was this week extended to some of the busiest airports around the world including London Heathrow, Hong Kong, Madrid, Paris CDG and Amsterdam Schiphol.
The mobile and iPad based apps show facilities such as gate locations, bars, restaurants, shops, toilets, information booths and baggage claim areas.
The system works by pinpointing a user's location within an airport using what the company calls its SmartFix technology - a way of tracking the device within the facility via existing GPS or wi-fi systems and calibrating the location onto the map.
The company has recognised the difficulty GPS devices often have within buildings, so SmartFix prompts the user to provide his or her own position by selecting a nearby landmark.
The roll-out comes just ten weeks after the service launched in 50 airports across North America. Point Inside originally launched to provide map services for retail centres.
The addition of ten airports outside of North America is the start of a major expansion programme for the business, says Brian Wilson, VP of marketing at Point Inside.
