I've tried some tools which convert PDF  to DXF to ESRI shapefile, but the
results are not really satisfactory, because by converting, some information
is lost.
The maps are created in Adobe Illustrator and the company creating the maps
has provided me an .ai and a dwg file.
But I haven't managed to make the dwg file work as a source of map server.
How do you do this? Do you use OGR? If I run ogrinfo on the dwg file, it
tells me that it can't open it. Maybe, a special driver is needed to open
the dwg file.
