Synopsis
On an island, a narrator reflects on distance and connection. The film discusses triangulation, a surveying method used for centuries to locate distant points. By measuring angles between known locations, surveyors can determine the position of a third point. This technique has been essential in mapping coastlines and establishing arcs of longitude. The documentary illustrates how this method has contributed to understanding the shape of the Earth itself. The runtime is 23 minutes.
