Google recently pushed out an updated version of Google Maps and with this update came the ability to download map data within 16km2 (10 miles2) whilst you have a sufficient data connection, so when you go out into the close-range wilderness you can access Google Maps without the need for 3G or Wi-Fi. Clever. The feature needs to be enabled in the ‘Labs’ menu of the new Google Maps (vers. 5.7.0) and you use it by long pressing on a location, selecting the bubble that appears then hitting the ‘Download map area’ option. Downloaded areas will be shown with a black boxed outline.
The map area downloaded only includes the default map view, so you’ll need data to view satellite view; load up 3D renders of buildings; search for places; and get directions. Since directions are left out, it’s best to know how to get to where you’re going beforehand ;). Hit the source link to download the new Google Maps if you haven’t already.
