SU7 AP Heightmaps FLATTENS Helsinki Photogrammtry.

Temporary(?) fix: remove  "EF_HELSINKI.bgl" and "EFHF.bgl" from folder "morko-dem-finland-heightmap-airports\scenery\heightmaps\finland".

BEFORE UPDATING REMOVE PREVIOUS VERSIONS

"Main file" contains the heightmaps for airports/flightplaces and POI fixes

"CGL-DEM vXXX Part1" and "CGL-DEM vXXX Part2" contain the "base dem" for whole area. Unless you know you need these, don't download. Base dem will be overridden by online data when close to the terrain  because higher detail is available from cloud. In PERFPLUS update asobo update their local cgls, there should be no more bumps -> these do not enhance the scenery.

This is based on data from NLS elevation models and laser scanning data 0.5p, 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.

If this mod is incompatible with a scenery that you use (floating buildings etc) you can remove the 3D heightmap from that airport:
 1. Navigate to morko-dem-finland-heightmap-airports\scenery\heightmaps\finland\
 2. find bgl that corresponds to the area you want to remove, most are ICAO codes. Otherwise refer to areacodes.png
 3. rename/delete said bgl. For example rename EFTP.bgl to EFTP.bgl.disabled

Mods known to work with this mod (doesn't mean others won't):

• Addons by WildLynxPilot
• Addons by Kumihiiri
• EFHK by Epixeri

Known issues in airport heightmaps:

• You tell me?

Known issues in CGL-DEM:

• Edges of covered area don't blend to the original in-game/bing DEM
• 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.

Out of date documentation and basic implementation to create native DEMs is available at github.com/muumimorko/MSFS2020_CGLTools
