Maps - Please do not store offline data in /tmp

[Sjors]

I have scrolled around the map in Locations [0] to download some map data of places I plan to go to. That way I can use the map when I am offline.

However, the data is stored in /tmp/diversity-maps/osm which gets deleted upon reboot.

Temporary workaround: tar all tiles and move them to a save place, copy them back after reboot.

Proposed solution: store files in a permanent location.

If the tiles are stored in a permanent location, then the Locations application should probably have a preference menu where you can allocate a maximum number of megabytes.

I think the main problem is that the disk space is fairly limited. Jeremy can tell you more about that - he is the author of locations.

In tangogps it works ok. /tmp is default but you can change configuration to point the cache dir to your preferred location

The Locations package provides om-locations-map-pack to store the downloaded data to create a map package:
​Create offline Maps

Yea, if you want to save downloaded maps, you can use ​Create offline Maps. That's the way for it. For now the UI has no ways to configure it.

The storage path is configurable through the config file since 2c362f86b598cd35a63977cb0e6d92d8883d932d on 0.2 branch. See

More work (limiting the total size used) is needed befre the path can be default to nand flash.
