[WIP] Building a world from tectonics onward

[worldbuilding pasta]

2 quick notes:

1, I've done some tests lately with exoplasim runs starting with 1 meter of initial global glacial cover; it takes a bit longer for the climate to settle out, at least 50 years whereas they usually are mostly settled within 20 years otherwise, but the resulting glacial cover is a lot more accurate, as well as the global average temperature. it does make some mid-latitude areas even colder than they should be, though.



2, I've seen at least some indication that T85 runs are better at reproducing the precipitation patterns in Africa and India, but I've never really got around to fully investigating it; this is a run someone on discord did for just 16 years (and I think it's from back when we used an earlier version of the topography script that was heavily land-biased)

This is a really good point and something I'll try soon. Thanks!

Out of curiosity, what do you mean by this? I'm guessing (hoping) this isn't the Image2sra_2.0.3.py script that I've been using.

I think this was way back before Ostimeus had released the script anywhere so don't worry about it

What do you mean ? I was trying to follow the tut on WBP but i found a bit of confusion on where to put Low pressure circles.

Sorry, was replying to bragg earlier regarding the image2sra script, I haven't used old-school forums in ages, I didn't remember how the reply stuff worked.

Am I wrong or places mediterranean in wrong positions?

That output almost looks like it came from one of ExoPlaSim's "snapshot" files, at least when I mistakenly use those to generate climates I get similar weird distributions of Med climates like in that example. I guess it could also come from the fact that a 16 year simulation isn't yet converged, so it could have wacky thermal / precipitation parameters.

I guess I have to try to mess with that program too... but is it worth the whole job of installation and so on ? Its seeming overly conplicate to me if the result is getting a 256 pixel map when I usually work at over 20k scale ?
