Here's a longer explanation of the terms:

10.1.1 says you must go through the Google API and not the servers directly, 10.1.3 is about offline caching, which is only allowed to improve the user's experience and up to 30 days and 10.2.ii states it shouldn't be used in connection with autonomous vehicles. The latter is still open to interpretation, becauseĀ  the maps aren't used directly for navigation, only for flight planning (i.e., the autonomous functions do not depend on the map, only on the GPS coordinates).

Some OS projects dropped Google Maps support in fear of the "do not cache offline" term, but I think engineers themselves interpreted the terms to mean "no caching whatsoever", but weren't actually challenged on violation of the terms in their project.

Mission Planner (3DR/APM) uses offline caching too, so you can bring the laptop into the field where there's no internet access. The spirit of the terms is that users need to go back to the service to get their data and that companies do not offer cached versions from local databases (or codings, etc), or that app developers do not pre-fetch entire local versions of an area (village/city) thereby bypassing the service for an extended amount of time.

I have read them Uriven...

but as Felix I am not a law expert :P, so I do not really know about if an open source project can use them or not. My concern is not about PPz, I would like to use these maps in another open source project and I was curious whether people here know something.

Regarding downloading google maps tiles:
Well, I'm not a lawyer so I don't really know...
At least nobody complained so far...

As alternatives for sat images you can currently select Bing or MapQuest Open Aerial (if it has tiles for that area).

One quick question about using Google maps.

Is it allowed using them in a project such as paparazzi? I do not know exactly the license.

On the other hand, what are other suitable alternatives? Openstreetmaps does not have satellite photos I guess, but they have topography?

Hi all,

just a quick note to let you all know that we changed the directory where the google maps tiles are stored in the master branch (verison v5.3_devel-282-g3fd4b18).

For consistency with other tile sources they are now in var/maps/Google and not directly in var/maps anymore.
So if you use latest master and you want to keep using your already downloaded tiles, you can simply copy all *.jpg files from var/maps to var/maps/Google.
