[OSM-dev] Mapnik script broken?

[Sven Geggus]

Hello,

I'm fiddling with mapnik, but am currently not able to generate
geographically correct tiles.

My generated tiles always seem to be shifted north by
approximately the height of one tile (I did not measure this exactly
however).

I'm using generate_tiles.py from svn more or less unmodified.

The Problem does not seem to be related to the postgis-database as objects
can be selected from there at the correct position:

osm=> select osm_id,astext(transform(way,4326)) from planet_osm_point where amenity='parking' and name='Weiherhof-Center';
  osm_id   |              astext               
-----------+-----------------------------------
 246878379 | POINT(8.4726817 48.9969750990528)
(1 Zeile)

This is exactly where
http://www.openstreetmap.org/api/0.5/node/246878379 is supposed to
be.

Any hint?

Sven
