Koppen and Holdridge

The last step in climate is to apply the Koppen or Holdridge mappings, based on the local temperature and precipitation properties.

I'm not at all convinced that Holdridge is working for me. But I like to keep it around just in case.

Overall, Koppen seems more intuitively correct.

A nice mix of types of terrain. For some reason I feel like Koppen is easier to work with. Maybe it's the palette. Using all this data, I assign a terrain value (such as forest or savanna). This lets me make a map which is more human friendly.

There's a lot of savanna here, as it turns out. I can live with that.

I think the next thing I'll dive into is individual resource research. I want to start gaming at some point in the next ten years, so it's necessary to get some actual stuff a party could use (as well as the historical simulation for background). That'll be a project in itself.

Temperature VI: PET

I have previously addressed potential evapotranspiration here, so I don't really need to address it again beyond a few minor updates.
