I don't want to say much about it, as I'm keeping some of the concepts pretty close to the chest.  However, this will be a war game, and I'm trying to determine worldwide resource distribution.  Economics will play a relatively simplistic but crucial role in the game, and so I'm trying to determine the following resources:

Energy: this represents the fossil fuels, i.e. oil or coal.

Ore: this represents the metals to construct your war machines, i.e. iron and copper.

Cash: this actually serves a doubled representation, both as actual capital as well as manpower, i.e. higher population areas are worth more cash.

I'm looking for good maps online that could assist me in determining how resources are distributed throughout the world, but most aren't all that helpful.  I need to rather realistic regional representation, not merely that Iran and Russia as a whole produce a bunch of oil or natural gas.  I need to know population density (actually, I've got a pretty good map of this, but any suggestion is helpful) and industrial regions (i.e. Hong Kong).  Any suggestions/hints will be recompensed in the next life :)
