There's no way you can extract the data at this stage. It's in the new terrain mesh bgl format which was introduced in FS2000 and some new features were added for CFS2 and FS2002.
This new bgl section contains elevation, land class (which is a land use texture map), decals (roads, shorelines), and 'flatten' polygons (and some other stuff). M$ has revealed absolutely no info on this format at this stage. I have cracked about 70% of the format which took me about a year! I can read land class files and possibly elevation maps, but only when they aren't compressed. You will only find compressed files on the net, and I have no clue what the compression could be, I assume it would be some 2D lossless compression, but I don't know enough about these things... On the other hand, the Satpac mesh is based on the AUSLIG 250 DTM, and by the end of the year we should have the better 90m SRTM dataset. Juergen, I assume your elevation support is the old FS98 elevation bgl commands? I have also cracked the 'flatten' polygons and the decal polygons, but decal lines remain a mystery at this stages...
