Generating a city or region from a height map image

[Lobby]

Hi, in recent versions of the game you can create cities and regions from height map images. Such images look like that:

The brightness of each pixel determines the height of the corresponding tile in the city. The brightness ranges from 0 to 255, with 10 being the sea level. Dependent on where you have your height maps from you may have to adjust their contrast and brightness. See the entry on Wikipedia for more information about height maps.

You can get real world height map data for example from http://terrain.party/

In order to generate a city from a height map place the height map image file into your TheoTown folder and remember its name. Then go into the game, create a new city, and enter the name of the height map file (including the file ending) into the seed text field. The picture will be scaled to match the selected city size.

Append #somerandomtext to add some randomness to the map generation in case you are not happy with the result (e.g. the biomes on the map).

Of course, you can do the same thing for regions. The result

The height map that's used here is a part of New York and was extracted using http://terrain.party/

Note how dark the image is because of the lack of hills in New York.

This feature is compatible with all recent versions of the game
However, the version for iOS doesn't support 16 bit (per channel) images right now. This is a special format that is used by some height map creators; you may have to save them with an image program to make them compatible with the game.

I know quality is bad due to my amateur skills but you can still read the comments to get more information

Hey!

Really been trying to get a map based on my hometown of Stockholm. I've figured out how to download a map but when I go to add it in theotown the game freezes.

I'm playing on a MacBook FYI.

Any advice?

What size is the image?
You might have to reduce the size in a graphics program if it is very large.

I tried a couple of different. But the one I have right now which i want is 317k. It shouldn't be too big I think. I can share it here. https://imgshare.io/images/2020/03/11/sthlm.png

Did you forget to write anything?

If it works for somebody else, is it possible to provide a seed based on the height map?

Append #somerandomtext to add some randomness to the map generation in case you are not happy with the result (e.g. the biomes on the map).

The game also allows you to generate a region out of a height map. To do that, use the following scheme for the cr console command:

Code: Select all

cr:{name:"New York",bmp:"ny.png",size:12,maps:[0,0,6, 6,0,6, 0,6,6, 6,6,6]}

See the topic about generating regions for more information about the cr command and how to use it. Note that you have to enable debug mode and experimental features in the setting in order to use the console.

I tried it but there was no water in dusseldorf i had to make the river thankfully it somewhat had an outline of the river, in amsterdam the whole map was in water

The brightness of each pixel determines the height of the corresponding tile in the city. The brightness ranges from 0 to 255, with 10 being the sea level. Dependent on where you have your height maps from you may have to adjust their contrast and brightness.

So you usually can fix that by adjusting the brightness of the whole image so that the area that should be water has a brightness of 10 or below.

Put the heightmap in the Theotown folder and then do the same thing as the first post.
