Nokia buys US geo firm Metacarta -

Finnish giant Nokia said it bought Metacarta, a privately owned firm based in Massachusetts.

Metacarta, said Nokia, has technology for "finding anything written about any place" - it provides geosearch and geotagging abilities.

The company lets documents from any source to be linked to appear in any map. Its Geositesearch product lets people do a geographic search on any content and provides search results ranking based on both location and text relevance.

Nokia did not say what it had paid for Metacarta, which currently has 30 employees. Its customers range from digital publishers such as Returers and the BBC, to US federal bodies, and energy firms such as BP, Shell, Total, Hess and Schlumberger.
