I have a TON of vector drawings available to me in PDF format that I'm georeferencing. So far, I'm doing it by converting them to PNGs and using r.to.vect to massage them. This is really tedious and the data isn't as clean as a straight vector conversion would be. In Illustrator, I can see that all the vector math is there. That is, the PDF isn't simply a wrapper around raster data.
I've tried opening the PDFs in Illustrator and exporting them as DXFs, but Grass ignores a lot of the data when I do this...they look very different in Grass once imported. I can export them as SVG from Illustrator, but surprisingly, there doesn't appear to be a single open-source tool available out there that converts SVG into some mainstream GIS file format.
Does anyone have experience doing this type of conversion? Pointers welcome.
