The Google Maps version for Android recently received a new update.
For those who travel by plane ( in the United States ) or they like to spend a lot of time in malls, the update is welcomed because it provides indoor maps of some public interest buildings.
The previous Indoor Google Maps version displayed some stores details, but now it also offers directions.
Also, with the new update, Indoor Google Maps also displays the floor you are on. This if you are in New York.
Still, the GPS signal is pretty weak in most buildings so Google had to use a database of wi-fi routers to be able to find out the location of a user. So, a big number of connected hotspots will offer a bigger location accuracy.
What we have to mention is that the service is available in the United States so users from other countries should not worry about the weak signal of the Indoor Google Maps service.
