Hi Martin, We now use Google groups for the mailing list: http://mapnik.org/contact/
This one is retired, so please post to the new list. But, a hint would be to use nik2img.py to test rendering. generate_image.py is hardcoded to zoom to Britain and may not be a proper way to display your own data in a custom projection. Also, try removing the Min/Max 'ScaleDenominator' limitation. Dane On Dec 20, 2011, at 2:26 AM, Styp wrote: > > Hi, > > I'm working on a custom xml to work with a navteq dataset.
