Building a better map of Europe

unable to retrieve full-text contentMore than a billion people use Google Maps each month to find their way around town and around the world. To help these people get exactly the information they need, the Google Maps team works constantly to ensure that the geographic data behind our maps is comprehensive and accurate. As part of this ongoing effort, weve just released updated maps for 10 countries and regions in Europe: Andorra, Bulgaria, Estonia, Gibraltar, Hungary, Latvia, Lithuania, Slovakia, Slovenia and Spain.

Todays update is part of a project called Ground Truth that began in 2008. Through this initiative, we acquire high-quality map data from authoritative sources around the world and then apply a mix of advanced algorithms, supplemental data (including satellite, aerial and Street View imagery), and human input to create a map that corresponds as closely as possible to the real-world facts that youd find if you were to visit that location.

For example, this update adds a new 70-km section of Bulgarias Trakiya motorway, which opened recently to drivers but hasnt been reflected on most maps of the region until now.
