When is Google updating Google Maps?

How has Google tagged places, roads etc in Google maps? And what is the process/frequency of updating them?

• Answer:

  Most of the changes done in already mapped world are done by the users themselves. These changes are done mostly using Google Map Maker, which allows users to create and edit Google Maps. This product makes it possible for Google Maps to reflect the real world more comprehensively, accurately and real-time than ever before. (See: http://www.nbcnews.com/technology/collapsed-i-5-bridge-gone-google-maps-almost-quickly-it-6C10067906.) Apart from Map Maker, users also just report issues using other reporting tools inside Google Maps, which are fixed by operators at Google. Time to time, Google also acquires data from other sources and merge them into their existing data, but it's not very common nowadays since in most countries the data on Google Maps is usually best data available out there and the third party data rarely add any value to it.
