noop, it is Navteq, which provides GIS data and Maps.
You can get your FREE API account in http://www.uk.map24.com/. Map24 is the equivalent of Google Maps, but you get the data from the source, with a definitely better quality for some areas (ok, ok, I put an emphasis in Greek Islands, where Google Maps is very poor...). For example, coverage for my island Ithaca (Ithaki, Thiaki, Ιθάκη, Θιάκι), Greece is excellent, in contrast to the likes of Google, Yahoo and Microsoft Maps.
