    Is there a zoomable Azimulthal-Equidistant map centered on North Pole online and/or what would be the length in miles and midpoint of a line drawn between Point Arena Light, Ca. And Cape May Light, NJ on a North Pole centered AZ map?

    Not that I know of, but you can get an approximation using

    Green = Great Circle, shortest route
    Red = Flat Earth shortest route (straight line)

    Globe Great Circle (Green) = 4154.7 km, 2581.6 miles.
    Globe Flat Earth (Red) = 4182.0 km, 2598.6 miles.

    Flat Great Circle (Green) = 4699.0 km, 2919.8 miles.
    Straight Flat Earth (Red) = 4673.5 km, 2904.0 miles.

    It's not a huge difference, as the closer you get to the pole, the more accurate an AE straight line becomes.

    An AE map is just a projection of a globe, so the distances will be the same - though you can't very easily measure anything other than north to south on an AE map, because the distance between lines of longitude increases the further south you go.

    Are you asking what the distance between those places would be on a flat earth map?
