Hello Bjørn, I had similar issues when first working with Mapnik. The only solution I found was to convert all my data to spherical Mercator, rather than try to work with a mix. No problems since.

For zoom level 1 only labels on the southern hemisphere (the two bottom tiles) are rendered - see the image attachment. The other zoom levels are rendered correctly. It works when using standard latitude/longitide projection (EPSG:4326), but not "spherical mercator". tilecache.cfg [country_labels2] type=Mapnik mapfile=C:\EarthAtlas\maps\merc_country_labels2.xml spherical_mercator=true metaTile=true metaBuffer=50 metaSize=2,2 merc_country_labels2.xml <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE Map> <Map srs="+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgri...@null"> <Style name="country_labels"> <Rule> <TextSymbolizer name="nor" face_name="DejaVu Sans Book" size="8" wrap_width="50" fill="black" halo_fill="white" halo_radius="1" dy="0" dx="0" vertical_alignment="middle" allow_overlap="false"/> </Rule> </Style> <Layer name="Cities" srs="+proj=latlong +datum=WGS84"> <StyleName>country_labels</StyleName> <Datasource> <Parameter name="encoding">latin1</Parameter> <Parameter name="type">shape</Parameter> <Parameter name="file">originals/countries_point_lonlat_sorted/countries_point_lonlat_sorted</Parameter> </Datasource> </Layer> </Map> I've also tried to reproject the shapefile before rendering the tiles - but the error was still there. Anyone else who have experienced this problem?
