Nokia is opening up its mapping software to developers by publishing the application programming interfaces (APIs) so that developers can use the service for their own applications.

The company is also updating Ovi Maps to include new features, such as satellite and terrain images and 3D landmarks in 200 cities, as well as adding information about weather and points of interest.

"It's about opening up innovation in mapping," said Michael Halbherr, vice president of social location, services and software at Nokia. "Ovi Maps is evolving from a consumer service to a live and dynamic platform for location-based services and content shared between the mobile device and the web."

Halbherr likened the Ovi Maps Player API to Windows Media Player, in that it allows third parties to use certain files.

Ovi Maps is also available in the browser via a plug in for Firefox and Internet Explorer, but not Chrome. "We go for browsers with market share," he said.

The Lonely Planet guide book company and Associated Press are already using the API to develop prototypes of possible future services.

Lonely Planet is using it to extend its existing close ties with Nokia and augment its online services, although no plans have been made to release the software as yet.

Associated Press has been studying the feasibility of using the mapping software to augment local and international news pieces.

Halbherr gave a video interview to vnunet.com recently, in which he demonstrated the mapping technology.
