I am not familiar with that map. The idea is that the space maps usually used in this mod restrict the Earth area to roughly the lower 2/13 of the map, and the rescaled files account for that. The NoLL files remove any geographical restrictions, and Orig is the original set of files which is used in the main mod and given here as an easy way to remove the modmod.
Unfortunately, for the last few SVN revisions the longitude/latitude restrictions for spawning were taken out, so that aspect does not work currently. But the other restrictions (e.g. for buildings) still apply.
