State whether the following is true or false.
Two interpolation methods applied to the same set of observations will produce the same surface.

  • A.True
  • B.False
  • C.True only at large scales
  • D.False only at small scales

Answer: B

Each method makes different assumptions about how influence falls off with distance, so the surfaces differ, sometimes markedly, between the observation points. They agree only at the observations themselves, where the data pin them down.
