Is there a way to locate Strategic Resources on the map?
Solution 1:
You can turn on the "resource icon" overlay which will put up floating icons showing what all the resources are (Ctrl+R, or click on the "toggle map options" button to the left of the mini-map and tick "resource icons").
If you then zoom out you should be able to see where the resources are quite easily, and what they are.
Solution 2:
Whoward's strategic view Overlay Resources mod is useful for this: http://www.picknmixmods.com/mods/f2968890-fe71-41d4-b609-805097365935/mod.html
