I think it would benefit the most from some kind of CAD package that can clip polygons for me, so I don't have to do all the math manually. I was rendering semi-transparent, so I needed to prevent polygon overlap. (or use a different technique like rendering to a texture then rendering the texture semi-transparent, but that gets into zooming artifacts and awkwardness) There was also the problem where roads can turn at sharp bends and the default polygons for that look horrible without some sort of smoothing around the corner. And UGH, intersections...

Geo::SpatialDB itself is just a database of things described in lat/lon, designed to be loaded tile-by-tile at varying levels of detail for the zoom level. I don't think that's really a PDL problem. The polygons it exports could be, if that's what a rendering pipeline wants to consume. But, PDL would need the polygon objects to be available without GLUT installed, because one of the use cases is server-side rendering.
