Feature proposal: Preload data via GPX track for offline mapping

[johnjohndoe]

Scenario

• When travelling I usually plan the route in advance. Specially, I prepare a GPX track for bicycle trips to loosely follow along. I imagine the same applies for people who hike.

Proposal

• It would be great if the Vespucci app could use the GPX track in order to download the respective area around the track upfront. A certain buffer might be useful to download data left and right of the track to some extend.
• I consider this especially useful as I am not using a data connection on my device - which means I do use Vespucci fully offline.

While we currently don't have such a facility, you can use offline data from http://mapsplit.poole.ch/ (or generate such sources yourself) which is generated every morning from data that is roughly one hour old (all the caveats about using old data apply).

The current plan is to implement this via a GPX track replay function.

👍 Which version will contain this feature? Is there documentation for how to apply it?

17.1 will have it, use

• load track
• turn on location based download
• turn on follow GPS
• playback the track

Note that you will have to up the auto prune limit massively or else the data will be deleted again. And currently the playback tempo is 1 point/sec which probably needs some tweaking for this kind of use.
