How does the game get info on sites (where are the sites coded/listed in-game)?

[tinkthank]

I have been repairing some maps and trying to mod some of my own, but cannot figure out where the sites are stored in-game. (I clicked on a whole bunch of files in the dom2 directory and tried to open them with wordpad, but no luck.)

I ask for two reasons. The Map Mod Doc in the dom2 folder lists a "short sample" of sites at the end -- but where is this taken from? That must be stored somewhere....
The second reason is the excellent Exel-Chart of sites I found on Sunray's site; this is a great chart, and I by no means want to criticize it, but there are a few errors in it (which I am correcting bit by bit); and s/he had to have gotten this information from somewhere too...

thanks much
