Planet texture generation code

Yes Minecraft can be good exampla of how to have huge maps with low memory consumption.
But From what I understand whtemple1959 is trying to make real time strategy game similar to OpenTTD. For RTS you need to have whole map loaded at all times.

If he is trying to make somekinda remake of OpenTTD he will probably alow player to modify terrain as it is posible in OpenTTD.

Nope, only need to load parts where things are happening and even then just what is needed.

Need bit more information maybe. From whtemple1959's message it sounded like RPG or adventure game. In any case, you can't have the whole world "living" at the same time. If you have key structures like airports or such, they can be separate objects from the terrain entirely. Can send aircraft to different airports and so on. Just when you load their area you would see them visually. Single cars in city streets, there's no reason to simulate that for whole world at all times.

Slightly related on topic is 1 of my units in nxPascal. Capable of keeping a huge world loaded up in memory at the same time. Unused parts are compressed, and used parts are automatically recompressed after certain time of no use.
