The Köppen–Geiger climate classification made simpler (I hope so)

[Azélor]

Prerequisites to this guide
• I made this guide for earth-like planets.
• This tutorial is mostly a follow-up of the tutorial made by Pixie : https://www.cartographersguild.com/s...ad.php?t=27118
• To get a better understanding on climates you really need to read this, the climate cookbook: http://web.archive.org/web/201306191..._cookbook.html


Software:
You can use any software you like to do this but using multiple layers is a necessity. I would recommend Photoshop or Gimp. Personally, I used Photoshop CS3.
I have worked on a script to make step 7 easier. It’s not impossible to do without the script but it’s much faster/easier since it’s automated. I works well with Photoshop.


Map projection:
Examples are made with the Winkle triple projection, it’s the same projection used by National Geographic. It’s useful because it minimizes all the types of distortions. But you can use other projections too. The euqirectangular is useful if you want to convert it to other projections later. Winkle triple cannot be converted into another projection, use it only if you’re sure you won’t need to convert it later. Otherwise, you’re better to use equirectangular.


Informations:
I used this as the main source of information : Köppen climate classification - Wikipedia, the free encyclopedia
But also other pages and some scientific articles.

The first part I did was to collect the info on the wiki and also elsewhere to get a clear definition for each climatic zone: what it is but also where to place them:
where they are the most likely to appear.

A reference for climates, may contain some inaccuracies:
