For example, Beijing, China's longitude is 116°23'30"E. The 116° indicates that it lies near the 116th meridian while the minutes and seconds indicate just how close it is to that line. Observers also needed to know the specific time and measure the moon and Mars' positions on a stable viewing platform- both of which were difficult to do at sea. In 1761, the chronometer was tested and determined to be accurate, officially making it possible to measure longitude on land and at sea.

ISSN: 2639-1538 (online), The Hidden Side Of Cities: Using Aquifer Thermal Energy Storage For Energy Saving. A (geographic) meridian (or line of longitude) is the half of an imaginary great circle on the Earth's surface, terminated by the North Pole and the South Pole, connecting points of equal longitude, as measured in angular degrees east or west of the Prime Meridian.The position of a point along the meridian is given by that longitude and its latitude, measured in angular degrees north or … In his measurements, Vespucci calculated the angle between his location, the moon, and Mars. These longitude lines break up the Earth in equal “slices” in order to determine where a point is located on Earth horizontally. Admire the research gone into this. The five major parallels of latitudes from north to south are called: Arctic Circle, Tropic of Cancer, Equator, Tropic of Capricorn, and the Antarctic Circle. The longitude of Seattle, Washington, for example, is: It’s this extremely precise system, when combined with the latitude system of measurement, allows people to figure out their exact place on the globe. On a map (diagram), lines of longitude are the vertical lines running from the North Pole to the South Pole and are perpendicular to lines of latitude. This problem was eventually solved by John Harrison, who invented a device called the marine chronometer which allowed sailors to determine their longitude position while at sea. 5.

Longitude divides the globe into east and west halves, centered on a line called the Prime Meridian, or 0 degrees longitude. In the early 1600s, a new idea to measure longitude was developed when Galileo determined that it could be measured with two clocks. Latitude was determined easily by observing the inclination of the sun or the position of known stars in the sky and calculating the angular distance from the horizon to them. It was hard to coordinate the schedule of trains because each city would have its own time. Shortly thereafter, there were several attempts to make a clock that could accurately tell time on the unstable deck of a ship. You’ve probably heard of latitude and longitude before.
