Using the Map Editor in Cities:Skylines 2

Import a height map

Generate the height map

To import a height map into the Cities: Skylines 2 Map Editor we need to create a 4096×4096 pixel 16 bit grayscale height map.

To generate the height map and overlay map image of an area of the Earth, we can use the following sites:

Create the directories


The editor selects the heightmaps from the Heightmaps folder

  • Create the “Heightmaps” folder for the height map files at “C:\Users\YOUR_USER_NAME\AppData\LocalLow\Colossal Order\Cities Skylines II”


The editor selects the Thumbnail and Preview images from the Screenshots folder

  • Create the “Screenshotsfolder for the thumbnail and preview files at “C:\Users\YOUR_USER_NAME\AppData\LocalLow\Colossal Order\Cities Skylines II”

Update the height map

  • Open the images in Gimp, a free open source image editor
  • Resize the image to 4096×4096
  • Check the image mode, make sure it is set to grayscale

  • Check the color precision, make sure it is set to 16 bit

Save the image in the new Heightmaps folder
