Different Kinds of Map Projection Robinson Polar / Azmuthal Goode’s Mercator & more……

Robinson Shape and size are both somewhat distorted but not extremely distorted

Mercator One of the simplest projections One of the more distorted Shapes are more accurate size is not accurate

Goode’s

Polar - Azimuthal

Problem…. Distortion!!!! (No, Greenland is NOT as large as Africa!

Why? THE EARTH IS NOT FLAT, but Maps are! This is the answer to a test question…..

IF you could map the round earth….

Great Circle Routes…. Which route is shorter? Kinda seems to depend on which map you look at…….
