  batik really doesn't want to work, I can render out a small svg with about half a dozen streets on it, but anything bigger and I get IllegalPathStateException from batik-rasterizer.jar, details below. I'm guessing there is an object somewhere near the middle of liverpool that is messed up.

Hi Thom,

I can't help you with .NET, but I just wanted to let you know that I have successfully rendered the SVG's using Batik and got the same output as from Inkscape. Just want to reassure you that there is nothing 'funny' about the SVG format.

I have come accross SVG libraries in the past that only render a subset of the SVG operators, which produce strange results when run over SVG's containing the full set. Can't comment on SharpVectors though.

Regards,
Brent.

before?

It seems to render various elements as solid black objects. The 
background rectangle fills the page black, if I remove that then ways 
are just solid black shapes.
