fixed Hump in middle of Tinian North Field

[Nealius]

Unload camera coordinates command does not work. Nothing is saved to my clipboard. Location of the hump is along the central road that passes perpendicular through the middle of the runways. 

 

North Field is known to be used for STOL exercises present day, and should be relatively flat. this topographic map shows it should have a gentle incline on the east end. No hump is shown. 

 

Summit of the hump looking west. Note the decline. 

 

Summit of the hump looking east. Note the decline on this side too.

 

Hump visible from distance on runways Able and Baker.

 

Present-day picture of runway Able, showing it to be mostly flat, and with significantly fewer trees.

Here's a camera position for you, I've tried my best to line it up with the screenshots you posted

Here's the one looking to the west: -camera 175.187876 0.043040 92.087912 -cameradir 0.006132 0.034124 -0.999399

And here's the one looking to the east: -camera 175.187876 0.043040 92.087912 -cameradir -0.044981 0.006807 0.998965

I'm noticing that these issues keep cropping up, there seem to be a lot of areas on the Marianas islands where the geometry is just off, and it's typically areas that should be flat IRL being much more hilly.

As for the trees, you're right, it should mostly just be undergrowth (though fairly dense by the looks of it).

It looks like Guam's Northwest Field is experiencing some terrain issues as well, though it appears flat. The abandoned runways are still used for STOL exercises present-day, but trying to land something there and you get thrown around and flipped over.

There's plenty of issues with the geometry all over the place if I'm honest and it's on all of the major islands.

If you follow the main road from around Apra harbour and follow it east, you see a load of bumps and some really rather alarming geometry (with roads with 60-80° inclines and bridges that in some cases, even the Caucasus map honestly does better on).

But all of the islands have issues with their geometry, namely roads that are nearly vertical, and areas being much more hilly and precarious than they actually are, and sometimes the geometry is just plain wrong, with varying levels of severity.

With me, my main gripe is placing things like SAM systems down - before the Marianas map released, I had gone over in Google Earth, C:MANO as well as some topographic mapping sites such as this one, such that I could find ample areas for SAM sites, FOBs, RADAR sites, etc, only to find that in DCS, the geometry is completely unsuitable and the foilage much too tall.

Personally, I think there should be a stickied geometry errors thread where users can post screenshots of geometric issues they come across, attaching camera positions, locations and supporting evidence.

I had the same issue with the SAMs. I placed some emitters for practice on FDM, south end, where the "ALT" map shows it being flat. The emitters end up on 10-degree inclined hills.

@NealiusI tried to locate the runways as shown in the OP, but I couldn't. Was this issue solved?

Still hilly across all four runways. Should be perfectly flat. 

 

The runways are on the north end of Tinian island. I've attached a mission that has a FARP there so it's easier to find.

I hadn't tried to take off from them yet. Now that I did, I agree this looks a bit like a motocross ride.

I'm doing a check with available raster data, compared to those from the game.

It's basically a ski ramp if you fly the P-51 from there.

Here's a comparison of real life and DCS altitudes in meters. We can clearly see DCS has a hump that doesn't exist IRL.

Looks like the hump has been removed, but the runway has been made perfectly flat with a constant elevation of 30 m/98 ft.

The real place increases in elevation from west to east, being about 23 m at the western extremity and 41 m at the eastern extremity.

Yep, looks more useable now, but there is still way too much vegetation, particularly tall trees, immediately surrounding the runways.
