I found this mapping program pretty useful:
Only this is not the latest version, it has some bugs (when you set a point you must fill in all fields with at least a space, if you don't next time you start it, it won't load)... so I tried to find the updated one and did in the Russian rf4 forums. There is an updated .exe in there, you can use but you need an account to download that attach.
I'm not sure if it is okay, so I won't put a link up, but I took the liberty to make an updated package. You can message me if you want it.
All credits should go to Shamon of course!
