Sorry for asking, but where can I find the original, minus the lat/long lines?
Oh someone ping me here, well this one is the original, but it has a crucial detail,
Q-BAM does not have a known projection formula, they have had past attempts to try to find out which projection it is but without success; so keep in mind that the
Q-BAM is not a symmetric map, the southern hemisphere is larger than the north and the east-west edges apparently have extended water pixels, so the grid of coordinates that I had assembled doesn’t fit perfectly.
Summarizing the way I set this up, the latitudes were done based on the supposed equator line (aka looking at the possibility of the cities where the equator passes in Q-BAM), after that, it was basically doing the same thing with other latitudes of 5 in 5 degrees going north (which hemisphere I think is more correct); the logitudes were made with pure mathematics (the length of the Q-BAM divided by 180), note that from east to west the Q-BAM is symmetrical (despite the extra water) and the primary meridian has two pixels.
Another very important thing: the
primary meridian of Q-BAM (or as I like to call
Qreenwich) is located over Oslo, Norway, around
11.5 degrees east of Greenwich (which is marked with the red line next to degree -10), this happens to try not to cut Russia and the USA in Beringia, something that unfortunately is not possible (and that is why there is the mistake of having extra water there).
