I’m repeatedly amazed at how Google maps manages to generate an accurate overlay to satellite photography. I wonder is the photography manipulated in some sort of matrix to make its xy coords mathematically predictable? I have zero maths skills so will live in wonder and confusion but if it is projection based (mathematically projecting a sphere onto a flat surface), how cool would it be if Gmaps let you select your projection? My current fave is the Peters projection which shows accurate areas (and a high shock value) and goes some way to helping us find ‘our place’ on the planet (I would say a few specks is a truer assessment than a Conquering Horde)
