@kgjenkins If I ever had ambitions to become a game dev, this chart would have disabused me of that silly idea.

To be fair we not only have lon/lat (yes in that order and I will die on that hill) but also tile coordinate y axis flipping

I nearly forgot about this short demo I made a while back... an Ultima-like adventure game in which you go on an epic quest for geospatial data! #geodata #apple2

EXIF image metadata has the craziest way to store lat/lon coordinates that I've ever seen... a sequence of 3 (degrees, minutes, seconds) values stored as rational64u numeric types

Screenshot showing latitude stored as a sequence of 3 custom number types. 3 because of degrees, minutes, and seconds. Each component number is a "rational64u" value, with numerator and denominator values.

I've never heard of "rational64u" data types before -- was this something invented just for EXIF?
