ability to share OSM tile cache with tangogps

[mascellani@…]

Hi.

This bug was reported as Debian bug #528320, see ​http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=528320.

Josm could share its tile cache with other programs that use OSM tiles, putting them in a standard location, maybe in $HOME/.cache (at least for Linux, don't know about other OSs) or so. This way, different programs could be serving the same tiles quickly, reducing at the same time the load on OSM servers.

Thanks, Giovanni.

I don't know how the tile structure of JOSM is, tangogps saves them in zoom/x/y directories. If JOSM does the same you can simply set a symlink to the JOSM tile cache directory (only one symlink for the top level tile cache dir).

Otherwise you can configure the tilecache dir in tangogps to point to the JOSM tile cache.

Thanks for the answers. I'm aware of this tricks, but I think that the submitter of the Debian bug had a more general proposal: the problem isn't just with JOSM and tangogps, but with all the programs that consume OSM tiles. Thinking of a shared cache between all these programs could improve significantly user experience for these programs.
