[OSM-dev] Mapnik overlapping tiles

[Anthony]

Okay, I've got some higher resolution imagery which I'm trying to use
in potlatch.  I've decided to use generate_tiles.py as part of Mapnik
to generate tiles from the Geotiff I have.  I converted the tif with
gdal to the WGS84 projection, and run generate_tiles.py on the
reprojected tif.  It works kind of well, but the tiles are
overlapping.  For instance, see
http://mcfly.org/tiles/20/283842/439031.png and
http://mcfly.org/tiles/20/283842/439032.png.  The front of the car is
visible in both images.

Any ideas what might be going on?  Or is there a better way for me to
be converting a geotiff to tiles?
