Tiago and I have been working on a svg to ac converter to create
airports from pdf files.
Most of it is done, however we still have 2 problems, the first is
that the code can't at the moment produce the accurate location of the
origin (lat/long) and the second is that most of the polygons making
the buildings are non convex, thus the ugly result in the following
screenshot.

Also svg2ac automatically fetches the altitude of the buildings from a
running FG via telnet.
In TerraGear we avoid the polygon rendering problems you are seeing by
doing a delauney triangulation ourselves and throwing away everything
outside the polygon boundary. It would likely be a lot of effort on
your part to do the same thing, but it is a technique that will work.
Sometimes you have to drag out the power tools to solve some of the
nastier problems. The good news is that it's only triangles ... :-)
