Flat Earth Investigations / Re: Peirce Quincuncial Projection
« on: June 05, 2018, 09:24:58 PM »I actually thought it was a good video, well made.I agree the statement is untrue, but it might be not as straightforward as that. Because few earth images are photographs as with a camera. Himaware-8 and the US's GOES satellites use multi-spectral imagers that assemble products from strips, including frequencies outside of human visible light. Whether or not that is considered a "composite" I don't know. I think not, but you might get sticklers contesting since it's not a single exposure photograph. I'm not even sure if any geostationary satellites have cameras with a FOV wide enough to capture the whole earth in one shot.
There's loads of thing wrong with the content, first point was the claim that:
"Every image of earth since the blue marble is a composite. Only one image of earth in existence."
Completely untrue. The NASA quote is taken completely out of context. The himawari8 satellite (nothing to do with NASA) takes a photo of the whole earth every 10 minutes.
The EPIC imager on DSCOVR (which is positioned much further away from earth than geostationary imagers) is multispectrum also, but I believe it's distance from earth, aperture and method of image capture should qualify it as a noncomposite image, even though it does combine 10 spectral channels to create images. The FOV, though, is wide enough to image the entire earth in one "shot," so even if Himarawa and GOES are disqualified from refuting the blue marble claim, I think DSCOVR (EPIC) isn't.

Interesting. I never quite understand the issue of composite images, FE people seem to confuse "composite" with "fake".
Surely the relevant point here is the images are said to have been taken from space. That's the bit you need to prove false if you're going to maintain FE belief, not how the images are processed or whether images have been stitched together.
