Questions about Sigma-Cartographer Mod (how to use)

[Nightside]

I think this mod can help me, but I don't know how to use it.  I didn't see any controls in game, am I missing something? 
I'm trying to bulk-generate every runway in the world from GIS data. My data has elevations, but I'm finding that RSS/Kopernicus does not really match elevations very well, sometimes it is off by 1000s of meters.
- Can I use Cartographer to generate a height map of RSS-Earth as it exists in game? 
- Does it work with Kopernicus planets?
- Assuming I can have it generate a height map, what are the limits of resolution? I'm thinking I should go to 0.01 degrees/pixel. 
- Again, assuming I can export a height map, can I control the extents? That is: have the longitude axis go from -180 to +180, with the prime meridian right in the middle, or it like kopernicus where the map goes from -270 to +90 (with -90 in the middle).
 
Thanks for your help
