Mask

# Generating a satellite mask¶

Based on the object and terrain height data the application can generate a mask image. This allows different ground textures below woods compared to the rest of the island, as well as no clutter below houses and streets. Same for the sea and water-land transition.

The parameters for generating the mask are are set in config/mask.yaml.

It is expected that the user will have to do some manual editing of the image before it is suitable for use in the game.
