Hello, your work is fantastic! It would be even better if it could input a map seed number, then generate the corresponding terrain outline, and plan the building layout based on the terrain outline. The generation rules of the map might be a challenge, but I have some good news. Two mod authors should be aware of the map generation rules. If we could contact them, it might be of great help.
Steam has a mod called “Pangu Map Editor”. One of the functions: “Preview Map Seed: After selecting this option, in the advanced settings for map creation, you can click on “Random Map Seed” or enter a specific map seed. This will allow you to preview the mini map in the top right corner of the interface ahead of time. The preview will take approximately 10 seconds or less - however, it is much faster than actually entering the game.”
Another mod author of this forum, Mitr, there is a mod that allows you to preview the map of the current seed.

Additionally, it is recommended to add a feature for exporting images, which will facilitate showing to other players.
