Although I use FS 2004 "FS Global SE" for my World Mesh, I also find that Stephen Rothlisberger's "Terrain Mesh for the whole World" invaluable for adding that little bit more accurate realism to the ground scenery!....hills and valleys!...

Whenever I wish to explore a new area in my FS 2004, I first add the particular scenery mesh to those areas in my add-on scenery library!
It makes a "World" of difference to the experience!
The hills and valleys become more pronounced, and more representative of the actual area your are travelling over!
Well worth a try!
