It’s been a busy day for Google. Earlier in the day they unveiled Helsinki, Finland in 3D, and the coverage is quite comprehensive. Google Earth Blog has the details.
Also, as pointed out by Google Maps Mania, StreetView imagery has been released for a few countries. This update includes a few major cities in Portugal (Porto and Lisbon), solid coverage over much of Switzerland, and also around Taipei, Taiwan.
All in all, a pretty busy day for Google!
