Google Maps 5.7 for Android has a new feature: you can “Download map area,” and in addition to this there are two other features “Scale bar” and “Measure.”
Ability to download Google Maps will be of great help for any person visiting a location where either data access telecom signal is not possible or he is not able to access for some reason.
In short using Google Maps for mobile, one will not require to carry a paper map.
The downloaded map areas can be managed in the Google Maps cache settings so that one can delete maps after it is no longer required. Alternately after 30 days, all downloaded map areas will be removed from your cache; they can be re-downloaded any time.
