I have never messed with any of the games of the IL-2 Sturmovik franchise, so I can't say for sure, but I am afraid that comparing a submarine simulator with a flight simulator wouldn't lead to any conclusion: in one case we have a world made for being observed from the sea level, while in the latter case the privileged view is obviously from top...

ROGER that. Thank you mate, the next release shouldn't take too long.
I will let you know if I need you to do some testing

So changing = 3 to = 1 would give us 30m (Also saw that commented out so maybe we can't do that)

Resolution for SH5 is 25m per height value is it not?
Forget about meters. Due to distance stretching caused by cylindrical map projections, and to the arbitrary scale used in SH5, we better use angles than meters as unit of measure.

The 30-Meter SRTM dataset that we want to use in game, has a resolution of 1" (= 1 deg / 3600) whereas SH5 RAW files have a resolution of 1.5" (= [1 deg / 24] / 100).

Theoretically, using github/OldCoder's exe for downsampling SRTM data to the SH5 resolution, we should apply a stepping factor of 1.5.
If a similar factor was applied correctly, for a tile of 1 deg x 1 deg, I would expect an output containing 5,764,801 height points (= 2401 x 2401) rather than the full resolution 12,967,201 (= 3601 x 3601) height values.

Yet, no matter what stepping factor I apply (tried with 1, 1.5, 2 and 3), I always obtain an output with 1,442,401 height values (= 1,201 x 1,201)

I hope I made myself clearer now
