[MapServer-users] How to avoid writing empty tiles with mapcache_seed

[Philippe Ghesquiere]

Hi all,

While creating a GPKG cache with mapcache_seed, I would like to avoid
writing empty tiles.
I know that <symlink/> can save disk space. But I would like to get rid of
these empty tiles.
Is there any parameter to achieve it ?

If there is no such parameter, do you have any idea for some post-process
SQLITE command to remove these tiles ?

Thanks for your help
Philippe
