Google today said it had updated maps for 10 countries and regions in Europe, bringing the number of countries it has mapped through its globe-spanning Ground Truth project to 40.

The new maps cover the following places: Andorra, Bulgaria, Estonia, Gibraltar, Hungary, Latvia, Lithuania, Slovakia, Slovenia, and Spain.

The update comes as part of Ground Truth, the 4-year-old effort to combine licensed map data with algorithms, photography, and old-fashioned human labor to create the best map possible.

In addition to new roads and highways, the update encompasses walking paths, ferry lines, building outlines, park boundaries, and university campuses, Google said in a blog post.
