To reiterate, the question is if the submission can stay on OGA. The question is NOT if the asset can be used by a Canadian/US citizen or not. Assets on OGA must be reasonably safe for Europeans, Australians, UK, et al as well. If images in the Public Domain are still claimed as copyrighted by the US government abroad, then they are an exception to the Bernie Convention. The questions in my earlier comment ( https://opengameart.org/comment/97510#comment-97510 ) remain unanswered.
Again, I agree with bzt on that point. It fell into the PD in 1927. It says "in the USA" but that is referring to the lack of information about other publications in other countries, not that it isn't PD outside the US. That isn't the same as work that is placed into a weird Public-Domain-but-only-in-the-US by the US military. the "in the USA" part of that book's license appears to be saying "did you derive stuff from this book? or a Spanish version of this book?" If it was actually that book and not "Una introducción al estudio de los jeroglíficos mayas por Sylvanus Griswold Morley", then your derivatives are truly from PD.
The most relevant part of what surt said should not be left out; "it's not really public domain."
Any time you add extra stipulations to a license, it is no longer that license.
"This is licensed CC-BY. just give me credit. but also, don't resell it"
Well, not really CC-BY any more, is it?
"GPL: if it's used with other art, that other art must also be GPL, but only if you're using it commercially"
Well, not really GPL any more, is it?
"Public Domain: Do whatever you want with it, but only within the United States"
Well, not really Public Domain anymore, is it?
For your own personal uses, I think bzt's assessment is fairly solid. However, since the question is 'what does this mean for OGA?', mmmnot quite as safe: Yes, I know, PD is more like the absence of copyright than it is a copyright license, but the underlying effect is, if it isn't one of the licenses we accept on OGA, and it can't be converted to one of those same licenses, then we can't host it here. Note that I'm not saying "we cannot host Technopheasant's FPS pistols". I'm saying "I am not sure if derivatives of 'Public Domain US Military' can be licensed as CC0 or not." It's possible the answer is "yeah, that's totally fine" but I'm not sure. That's the part we need more information on.
Until we have that additional clarification, I must mark those derivatives as having a licensing issue. Because they may not be safe to use outside the US, and that is not something we expect any of our users to govern.
@bzt, please don't say stuff like "not possible" when it is not only possible, but easy. Is it possible to have the file saved as monochrome palette? no, probably not, but that isn't what Gaymoo was asking, nor are the files currently stored as an actual monochrome palette anyway. The sprites themselves are still monochrome even if the file's palette wouldn't be. An indexed palette with 1-bit transparency works just fine. The attached is less than half the file size of the original. If gaymoo mentions an interest in the intricacies of marginal gains in storage space and load times of overly-complicated image handling in game engines, then we can discuss more, but otherwise that kind of stuff is off-topic on this thread.
@Gaymoo: eh, for almost any other color set, it may be more useful to have a transparent background, but for black and white assets like these? It is trivial to just select all white (or black?) pixels and convert to transparent, so I would say nah, no need to submit a transparent version. The developer who wants to use it can do that if they need it. It certainly doesn't make it less useful if you choose to do so, though. More variety of useful forms is always better than less. :)

Yes, as far as I know, all NASA images are NOT CC0 / Public Domain. That doesn't mean that none of them are, but most are not. It also depends on which NASA images you're talking about. For instance, the ESA/Hubble images are under CC-BY 4.0:
yes, there are some vector graphics on OGA. Unfortunately, there are no categories just for vector graphics. The best way to find them is add the word "vector" to your search and/or search for the tags ".svg" or "svg" or other common vector file format extensions.

Ah, I see! "Inter Governmental Oranization". Interesting. Good find, marko. Thanks.
I'm curious what that is. Do you have a link to the page where it mentions CC-BY-SA 3.0-IGO?
Yep! As long as you're getting the images from https://esahubble.org/images/ they're all CC-BY 4! :D
Some of the Credit: text is kind of long, depending on the image. Just be sure to include the full text of it.
