Better opening site selection map -- mod?

[mzonk]

I'm looking for a mod that can make info on the map sites at the beginning of the game more easily gathered.

I have some specific criteria involving the terrain types (I prefer mountainous) and types of stone available (I prefer sandstone and granite).  My problem is that the map does not readily differentiate flat from hills from mountainous, etc.  I checked the list of mods, and there is none available that remedies this difficulty.  Is there a mod out there that I missed?
