You have a rather optimistic view of the capabilities of most nations to
handle development of truly accurate x-y-z topo data sets. And once you do
have that data, you have to have a guidance system that can read it, remain
compact enough to fit in your missile,

You do realise, you can get hard disks small enought otfit in your
hand, that store tens of gigabytes these days?

You do realize the problem isn't *storing* the data, it's *generating
and integrating it*. It's not a matter of storage, or CPU capacity,
but of analysis and algorithms. (A friend of mine recently generated
a 3-d topo of our county as the first step in building an integrated
GIS for the local water department. Took six months.)
