@vespucci_editor I do not have data for phone, there's no internet. Can I use Vespucci to record where I go and then upload later when I'm on wi-fi contribute to map?

@shaul it is possible to use vespucci in a completely offline fashion including editing offline and unloading later. See

And naturally you can record a GPX track and upload it later. However if you just want to that the app is probably a bit overkill.
