For example, Britain’s national mapping organisation’s brand is associated in our national consciousness with going to a small shop in a quaint village to get a map showing how to walk up a mountain. It’s called Ordnance Survey. If that sounds like Artillery Research to you, that’s because the project started because the king wanted to know how to accurately bomb Scotland.
i don’t even understand what you think ‘straight’ and ‘curved’ even mean at this point.
I’m talking about how in this image, the upper curved line is shorter than the straight line that follows the equator:
Because the curvature of the earth is greater than the curvature of the upper line. So by taking the upper curved line, you “skip” some of the curvature of the earth.
