Description:

Lambert solves a geometrical problem, viz. to reconstruct the course of a ship at sea on the basis of observations with a plane table on the shore. The problem is originally in Marinoni's De Re Ichnographica (1751), which Lambert read early on (1752). Lambert here reduces this problem (the most complicated one in Marinoni) using algebraic methods. Since many observations have to be reduced to solve the problem, these studies constitute one of the starting points for Lambert's work on the theory of errors.
