[WIP] The SH5 EcoMod

I have received your files. The recompiled exe works now, though, whatever stepping value is used as its argument, the resulting .txt output contains 1,442.401 (i.e. 1,201 x 1,201) height points, which is equal to one third of the original resolution (stepping factor = 3).

For our purposes we need to apply a stepping factor of 1.5. Using that value I would expect an output containing 5,764,801 (i.e. 2,401 x 2,401) height points.

Any idea on why the stepping factor doesn't work and how to fix it? I have the source code that you sent me, but I know nothing about C++, and even if I started learning it today, I am afraid it would take long before I could figure out the problem by myself

Not following you here.
Height points in a RAW file is 10201
It's 101 floats x 101 floats

From looking at the source code I see this.......

const int secondsPerPx = 3; //arc seconds per pixel (3 equals cca 90m)

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?

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...

btw i just installed this mod in my mod list damn look awesome ....

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

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

Could be this line in the source.............
const int totalPx = 1201;

I'm reading the code as I do back ground checks on new applicants for jobs.

Maybe try using the data extractor yourself first... maybe I am doing something wrong though I doubt that

Okay, thanks. Check your email

Had to go back to Cleveland for a few days but I have the files.
Now I just got word I have to go to California for a few days.
