The three point problem - to make a geological map
A demonstration of how to make better geological maps using the "three point problem" to predict the position of planar geological boundaries, interpolating them between outcrops. Part of "The Shear Zone" video channel. A copy of the map is available on the Shear Zone website (see link from Channel home page).
