To load the static geometry you can either use
dbLoadObject and load the universe.dbo file, or you can use
dbLoadStaticObjects which will load the object with the added bonus of using portal occlusion on the map which is a definite advantage.
(Note: the portal occlusion will only work on the FPSC maps, I'm not sure whether this function will load any object regardless of occlusion)
But to load all of the dynamic entities etc you would need to parse the scripts or whatever it is that FPSC uses to store the map objects.
