to Toofri and Don.Edwards for theirs advises.

Here screenshots:






Dowload Earthnight 16 k png.zip now ! (~ 57 Mo)

Bye !

Can you provide a comparison between how a particular city looks with the standard texture and how it looks with the new one? That way people can decide if downloading the new texture is worth the wait.

Soooo....

How long before we can get textures with one FOOT per pixel?

I'd LOVE to see my house in Celestia....

the largest map i was able to find was The Defense Meteorological Satellite Program (DMSP) witch i think was 42k b&w tiff or .dem

So does anyone know if these night maps are accurate representations from what the earth would look like at night? Of course I've been in a plane at 5 miles and looked down... and the lights don't seem nearly as bright as they do looking down from 200 miles higher (in Celestia). Yet I assume these night light maps are pulled from real sky shots...?

Is the night side of Earth really that blue? I know there is some light scattering around Earth's limb, but the blue in the screenshots seems ... intense Is this a real effect?

Is it once again a case of a favourite question here on the forum....
....What does the human eye actually see compared to an image created by a "camera". ?

Anyway, here's an interesting website.

well what the eye sees and what the camera saw are two very different things . So for me my earth night map is an artistic view
the blue is to show where the land is ,as to bleak water . The brightness of the lights is as a camera would see it ,because with the unadded eye only the most bright would be visable

some on this fourm go for what the eye would see , and others like me do an artistic look . so the upshot is it is in the eye of the beholder .

Thanks for the info, John. Definitely in the eye of the beholder... it's just nice to know which is which. Sometimes I'm in the mood for a pretty fly through the galaxy just for its own sake... sometimes I'm in the mood for a "Wow... this is what it REALLY would look like to my eyes" trip. Just depends on which part of the soul one is trying to satsify at that moment.

Though, for terminology clarification, I would add the distinction isn't necessarily between the "eye" and the "camera"... a camera photo can be taken to simulate exactly what the eye sees OR it can be taken in such a way (longer exposure, different wavelengths, etc.) that is NOT what the eye sees. It is, as you later said, really between "the eye" view and "the artistic" view. A "camera view" can be used in the service of either.

In any case, thanks for the link, T. I e-mailed the site and asked them the "favorite question" regarding their pictures... I shall post their response.

And just a question, is it normal the forum is very very slow ? i thinks it isn't my Adsl's connection.

I agree with you and I think it is more beautiful to see the night side in "blue" than to see in "black", isn't you ?

Bye!
