What is a map projection?

  • A.A way of printing a map in several colours
  • B.A way of representing a curved surface on a flat one
  • C.A way of measuring distances on the ground
  • D.A way of naming the features on a map

Answer: B

Correct answer: A way of representing a curved surface on a flat one

A projection is a systematic transformation from positions on the ellipsoid to positions on a plane. Because a curved surface cannot be flattened without distortion, every projection distorts something, and the whole subject consists of choosing which distortion to accept and where to put it.
