About this file


  • DEM for Finland created from NLS elevation models, ground resolution is about 20 meters.
  • 3D terrain for 186 airports / flightplaces / emergency landing places / helicopter landing areas (:P) in Finland, ground resolution 4-5 meters
Regarding airports:This is based on data from NLS elevation models, with minor fixes done on airport areas in case source data is not up to date or has errors.
If you spot errors, please let me know, with as much detail as possible.
Install by extracting to Community folder as usual, remove previous folders when updating to be sure that there is no leftovers.

Recommended mods/modders:
Mods known to work with this mod (doesn't mean others won't):
Known issues:
  • Edges of covered area don't blend to the original in-game/bing DEM
  • Peak elevations might have small "spikes"
  • Sub-optimal file size
For creators:
Uses priority 20 and 21 to override default airport areas without seaming. So if you want to build something that uses this as a baseline, use at least priority 22 if you do terraforming or additional heightmaps over this one.

Documentation and basic implementation to create native DEMs is available at
Please post technical question and comments at github or at forum: MSFS - Everything about CGL generation

    While at some parts of the region it improved elevation by a lot (especially on a lot of small islands), unfortunately it also created a lot of hilly terrain where the Sim update fixed them. At some cities I also noticed the elevation data cannot distinguish between the hill and a building - again, creating a lot of bumps where the terrain should be flat. So, while it can indeed improve the shape of the hills unfortunately it works exactly the opposite way where terrain is mostly consists of fields or a cityscape.

    Hi! thank you for this game changing addon! I had a look at your github page, I wanna help and make countries with high resolution as well. I just dont quite understand your tool completely. Can you provide some kind of tutorial? That would be awesome!

    Even the parts of Norway that was included looks better. Keep'em coming. Thank you!

    Excellent addon, Finland looks totally different in a good way. It's great to fly around and enjoy the scenery,

    This is an amazing job! Thanks! The DEM creation tool is great too! Have you also thought of a tutorial to better understand how the instrument works? Finland is hilly and in my opinion in countries like Norway you could better appreciate the custom DEM!

    I'm currently refactoring it to be more simple to use, with some feedback to the user. Norway and Alps would indeed benefit more of it, and they will get a makeover in due time. I do hope though, that Asobo will in time get the best open data and bake it into their base DEM, from all over the world.

    Thank you very much! I hope that Asobo is faster at fixing bugs than we have been carrying out since the first patch! It goes very slowly. I just hope that Asobo completes the SDK. I am waiting for the management of the water masks but unfortunately still nothing!

    Thank you very much. I think a lof of simmers were waiting for these . There is an excellent resource of LIDAR data for Slovakia specifically mountains as High Tatras ,Low Tatras and others which you can use under creative license. I
