For the mesh (for the level of terrain, to replace the sometimes flat world with correct hills and valleys). From Pilot (Those are working the best with FTX Global Base) there is FS Global 2010. this one contains the entire planet on a reasonable level of detail. They have also a newer version, FS Global Ultimate, with more detail than the older one. This one is devided in three products, one for America, one for Europe and Africa, and one for Asia. Beside there is FS Genesis, that has even more detail but comes in smaller regions and is not fully compatible with FTX Global Base. Beside those, it is also a good to have FTX Global Vector. This brings roads, rivers and coastlines on the wright place. On the side of ORBX they have some nice demo pictures of FSX without FTX Global, or with only FTX Global base, and as last with base and vector. It's prety impressive.
