Latitude and longitude. Global address
Description
Every point on earth has a unique global address, which is described by the system of latitude and longitude. With today's satellite navigation systems, we can find latitude and longitude positions with an accuracy of a few centimeters. This program describes how the system of latitude and longitude works, clearly defining key terms and concepts with the use of diagrams, illustrations, and video footage. The history of latitude and longitude is examined, from the early experiments and charts of Eratosthenes and Ptolemy to the inventions of the late 18th century allowing mariners to find longitude at sea. The video also reviews the use of latitude and longitude today, including electronic navigation and Global Positioning System satellite technology. This video is an excellent resource for geography, world history, and earth science classes.
