Would love to see som flying from Norway and its scenery.
How it looks in outerra

Please?

[cameni]

Norway doesn't look very nice now because of the fact that current dataset does include only 1km resolution data above 60° latitude. But we have got the permission to use data from Viewfinder Panoramas that will allow us to have a consistent resolution for northern parts of the world, and also to use even finer resolution for mountainous regions (where it matters most).

We will be preparing a new dataset, but first we have to rewrite the tool used for it - it needs to be optimized using CUDA or OpenCL because it now takes insane amounts of time to process the data and it also contains several bugs.

[tknudsen]

That sounds like an excellent idea, ill be looking forward to some screens in the future then, awsome work you guys put in.

The most int. part is that your say there in fact is coverage above 62N degrees with resolution under 75m (arc 3 is it?)
In regards to Microsoft Flight Simulator we have been looking for this some time now. For Norway there is an LOD10 (35m) mesh and buffer mesh LOD 5,6,7,8 (that gives detail in the distence only, but not all that suited for FSX (works, but...)

So it is with great int. that I am watching the Outerra project and its work.


Once again, from the bottom of my heart, thanks for your development, much appreciated

The coverage map of Viewfinder Panoramas data is here. These are 3'' data extracted from topographic maps. Only some parts of Siberia and Svalbard are still missing.

[tknudsen]

Thanks, and the southern part is covered somewhere els right?

[cameni]

Yes, the southern part below 60° is already included in the global SRTM dataset. There exists also a newer Aster dataset that was supposed to provide global 30m resolution data for most of the world. Upon reviewing it we found that it is in fact less precise than SRTM, and what's worse - it contains very noticeable artifacts that make it totally unusable for Outerra.

[tknudsen]

Ok, I see

Well time will show, hopefully there will be a new shuttle mission some time in the future that aim to cover more of the world, more spesific data and better quality.

My question is tho, does America have the most detailed terrain in Outerra?

[cameni]

No, we are using 3'' data for North America at the moment as well, instead of the 1'' that are available. New compilation will probably include 1'' data where available, and the resulting dataset can be stripped of detail levels when needed - for some types of games it's not necessary.

[tknudsen]

Sounds excellent sir, but where would you say in Outerra the best mesh resolution is? See that Himalaya have excellent resolution, might I be right asuming that this is 3" ?

[cameni]

As I have said - resolution of 3'' is used on all land below 60° north, and 30'' on the rest of the land and seas. Himalayas use 3'' as well, although there are some places where the data were interpolated (so called "voids") and the quality is lower. Viewfinder Panoramas data can be used to fix these as well. Generally, mountainous regions would benefit from 1'' data, gaining finer erosion patterns.

[tknudsen]

Ok, Thank you

We are now in the progress of making mesh for X-plane with the link you provided
It will be int. to see how it comes out..

[Jagerbomber]

I'm curious. (3" is amazing to me.   )  Why do you add the "artificial" bumps on the hills/mountains (I forgot what the term was) if you have a 3 inch resolution?  (I could be understanding this completely wrong.  )

[cameni]

No, that's arcsecond, an angular measure. As they say, not to be confused with the symbol for inches

It corresponds to roughly 90 meters (~300ft) at equator.
A dataset with resolution 3 inches would be insanely huge.

[necro]

Which imaginary resolution do you gain with extrapolating? I think you wrote that there is no physical border because of your floating point space but im not sure. Actually you should reach 3" :p

[Jagerbomber]

Ah, ok.  I should have known that.  

So where is each data point?  I'm assuming they make a grid and have 4 for each 3" square (curved/distorted to make the shape of the earth, at least when the points are applied to the engine).
