           Summary: Prepackaged compressed cached tiles using webp?
           Product: marble
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: wishlist
          Priority: NOR
         Component: general

  Target Milestone: ---

Hey guys!  One of the really great features of Marble is that it can be used
offline, but large amounts of map data can be extremely large, and there's not
really a good way to do bulk downloads.

To make this easier, a feature could be added allowing either png or webp
tiles, choosing png if available, along with a second feature defining a simple
.zip format for packaging complete complete maps, tiles, metadata, points of
interest, and all.

A quick test of this shows that a lot of the larger OSM tiles can still be
compressed 3x or more, despite not being photographic, with most seeming to be
around 2x, with decent enough quality for something largely functional like a
map.

The files could then be distributed via Torrents much like Kiwix .zim files
currently are.  This would even enable some educational distros to include
low-res maps out of the box!
