You really need separate levels of detail (LoD) for what you're trying 
to model.  When the whole planet is in view, even the largest mountains 
occupy only a handful of pixels, and therefore a low resolution map will 
do fine.  For closer views, you need greater detail, but only of the 
areas that are actually in view.

So you need the capability to tell what's actually in the camera's view, 
and to parse the maps for that area for the level of detail appropriate 
to that view.

John
