By understanding the best way to learn latitude and longitude, you possibly can open up an entire new world of data.
Understanding Latitude and Longitude
Latitude and longitude are a coordinate system used to pinpoint areas on the Earth’s floor. Latitude measures the gap north or south of the Equator, whereas longitude measures the gap east or west of the Prime Meridian. These two coordinates, when mixed, permit for the exact identification of any location on the globe.
Latitude is expressed in levels, minutes, and seconds. The Equator, which kinds the dividing line between the Northern and Southern Hemispheres, is designated as 0 levels latitude. The poles, positioned on the prime and backside of the globe, are at 90 levels latitude (north and south, respectively).
Longitude, then again, is measured from the Prime Meridian, which passes by means of Greenwich, England. The Prime Meridian is designated as 0 levels longitude. The road extending reverse the Prime Meridian, referred to as the one hundred and eightieth Meridian, serves because the Worldwide Date Line.
The Earth’s floor is split into 180 levels of longitude, with 90 levels extending each east and west from the Prime Meridian. The Japanese Hemisphere encompasses the world from the Prime Meridian to the one hundred and eightieth Meridian, whereas the Western Hemisphere occupies the world from the one hundred and eightieth Meridian to the Prime Meridian.
