Hello,

first, thank you all for your hints.

I think this is the next thing i'll try.  I just downloaded the latest version
of planet_osm and i'll install in WGS84 (if that does not break any other
programs / scripts).  I mainly use mapnik.

It also looks natural to me to install in WGS84 and if that also solves some
problems, that's great.


Best regards,
Torsten.
