Default Curvature of the Earth

Hi,
Just a quick question really. Do the maps model the curvature of the Earth? I'm wondering as a way of avoiding radar detection by long-range radar systems. I'm sure it is likely to, but I've never been up high enough to look!

Thanks in advance,

Tom

Curvature of the earth is visible in DCS World.

Thanks, thought it would be!

Mind you, keyword - "Visible" - in Nevada map (and Normandy, perhaps?), while it was NOT in old Caucasus so I don't think it's in revamped either (haven't flown high enough to notice yet).

That being said, not sure if it's "modelled" in a context you think about. Map grid and navaids on all terrains still work like projected on flat surface and I don't think more sophisticated stuff like radio wave propagation (apart from mountains vs flat) is affected.

From memory the map technology can create spherical (or part thereof) worlds, but all the existing maps were started before that became possible and so are 'flat' with 'sphericism' applied after the fact as part of the simulation.

The effects are there, the cause isn't

A long time ago I did a polar circumnavigation of the world on the old Caucasus map to prove it was flat. The Poles in DCS were actually single points on the map you could fly circles around, so if you try circumnavigating along a line of constant latitude, you would most likely end up traveling in a large circle around the pole and if you left the West side of the detailed portion of the map, you would come back on the East side even if the world is flat. Even in real life, staying on a line of constant latitude (other than the equator) requires you to perform a slow continuous turn. For this reason, all such tests should be performed along longitude lines.

During my polar circumnavigation, I started flying my A-10C from Georgia towards the South pole. Some of the navigation equipment stopped functioning properly after passing the south pole, but enough remained operational for me to complete the full circumnavigation and return to the same grid coordinate of the map that I had started my journey at. The map there was completely blank, proving that the DCS world was flat. (I think this was in 1.2.X.)

Now that there are a few new maps available, (especially since the mentioned possibility of EDGE supporting spherical maps) it may be interesting to try tests like this again for each new map.

As to your question about the radar horizon. I remember seeing in the patch notes at one point that DCS does in fact simulate the radar horizon, whether or not the world is flat. See here: https://forums.eagle.ru/showthread.php?t=147601

I almost pissed myself reading that it will be something like this:

Default Earth Curvature

Do we haved curved maps now or (still) not?
