A waypoint is an intermediate point or place on a route or line of travel, a stopping point or point at which course is changed, first use of the term tracing to 1880. In modern terms, it most often refers to coordinates which specify one's position on the globe at the end of each "leg" (stage) of an air flight or sea passage, the generation and checking of which are generally done computationally (with a computer or other programmed device). - Source: Wikipedia
