ATS concept map (fanmade)

[Trakaplex]

Interesting how big the 1:15 UK is. You can almost lay it across 1:20 Texas. Are you sure you calculated the 1:15 UK accordingly @ads678? And ATS might bring a Texas-sized chunk with Oklahoma, the Great Plains, and the Dakotas within a year or two.

[ads678]

Yeah, forgot about 1:15 for Britain, corrected the post.
Interestingly, OK+KS+NE combined are smaller than HoR (~600,000 vs estimated ~700,000 sq km).

I am curious, how did the 1:15 UK look like?
Comparing the current to the ETS2 background map, it looks more like the IRL size map.

Here is the comparison. I used thetruesize service, also ATS map was scaled down by 5% because of scale difference.

Awesome, I was just about to bug you about making an updated comparison image!

BTW, I was wondering if you could put together a similar comparison of the current ATS map and the map at release.

Regarding the ETS2 scale, the background map scale ain't a straight 1:19.
North/south, it is around 1:19,7 Berlin 1 of the cities crossing it. Counted from close to Karlstad, to east of Palermo.
West/East on height of Montpelier, it is about 1:19,64 . Counted from close to Montpelier, to Pleven.
The same, on the height around Kotka. Gives about 1:19,55 . Counted from Bergen to St Petersburg.


USA, west to east, from Gold Beach, Oregon, to north of Boston MA, gives a scale of 1:19,67
Laredo TX to around Boca Raton FL 1:19,28

Biggest difference is the time scale, for both maps, I think.

Shiva, numbers that vary in the way that yours do suggest that you may have used the wrong map projection to run your calculations. You may wish to double-check that.

ATS appears to use Lambert Conformal Conical with standard parallels of 33° and 45°. That should yield pretty much exactly 1:20 (except for SCS's "coastline cheating" in Texas and L.A., obviously). I don't know which projections are used by the two parts of ETS2.

Edited to add: I looked into it myself and couldn't confirm 1:20 using LCC. I think we may both be using the wrong projection. Not sure atm which the right one would be.

[ads678]

@Shiva So ETS 2 and ATS have basically the same map scale?

@rbsanford Ok, done. ATS 1.0 vs ATS 1.46

nautofon, I do count ingame, in the editor.
Or, the background map of ATS, that I gridded.

Counting is done like this.
grid/sector lines divided from the IRL kilometers.
The result divided by 4. One sector is 4 by 4kilometers

ads678, for a flat map? quite close.
Depending on how the map is flattened.
As far as I know, the ingame background map is flatter than a pancake.

North/south, Roseau, Minnesota, to Houston "just south, where I-69 has turned and goes west" 1:19,6759.
2125km , 27 sector/grid lines passed. Line 0 is never counted.

Shiva: The background map isn't a real projected map, it's stitched together from transformed images. These images don't line up exactly along their seams most of the time. The positional error caused by this varies, but can easily reach the claimed 1-2% scale difference from 1:20. This means your methodology by itself has inadequate accuracy to be able to support your conclusion.

Additionally, from your description it seems you're directly comparing geodesic (IRL) distances to projected (map) distances. This has a significant error as well. Its size depends on the map projection, but it's often much more than 2%.

Now, you might perhaps still be correct in saying the ATS scale is 1-2% larger than 1:20. But I don't think there's a way to say anything for sure without knowing how SCS defines the scale and the projection, and sadly I do not. (I thought I did before, but it seems I was wrong.)

[Shiva]

Yes, the map is stitched together.
Yes, not all cities have their centers on the exact center point.
The IRL distance, I took with google maps.
Time scale used by SCS, does not mean that the map scale itself is the same.

North/south scale, is almost the same, for both games.

I could someday get comparisons on the diagonal distances.

ETS2 and ATS, both are around 1:19,5 in scale. +-0,2 I would say. Map scale, that is.
