Understanding Latitude and Longitude. Because the address is in numbers, people can communicate about location no matter what language they might speak. A global address is given as two numbers called coordinates. It has horizontal lines and vertical lines that intersect. A location can be mapped or found on a grid system simply by giving two numbers which are the location's horizontal and vertical coordinates; or, to say it another way, the "intersection" where the place is located. Latitude Horizontal mapping lines on Earth are lines of latitude.

Longitude and latitude are tools that pinpoint any location on Earth. But the latitude and longitude system is the basis of many of those mapping apps, and an understanding of how to read those coordinates is a great way to increase geographical awareness and communicate global addresses in any language. Latitude and longitude are broken into degrees, minutes, seconds and directions, starting with latitude. Under the longitude and latitude system, the Earth is divided into a grid of horizontal and vertical lines. The horizontal lines are called latitude lines; because they run parallel to the equator, they are also called parallels of latitude. The starting point for latitude lines is the equator, which is at 0 degrees latitude. Each line of latitude both north and south of the equator increases by one degree, until you hit the North and South Poles, which sit 90 degrees north and south, respectively, of the equator.

Latitude and longitude are measurements of location on the globe. If you know how to read latitude and longitude on a map, you can determine the geographic coordinates of any spot on the map. While online maps make it easy to determine latitude and longitude with the click of a button, sometimes it is helpful to know how to do it on paper. In order to read latitude and longitude correctly, you must first understand the basic concepts behind these measurements. Once you have the basics down, learn how to identify latitude and longitude markers on a map and pinpoint exact locations.

Before we dive into the reading of GPS coordinates , it is important that you have a good grasp of the GPS system and basic knowledge of the geographical lines of latitude and longitude. This is made possible by the network of 24 man-made satellites, called GPS satellites, which orbit above the Earth at great speeds and precision. Originally a system used only by the military, the GPS system became available for use by citizens almost 30 years ago. It is maintained by the U. Department of Defense. Reading and understanding GPS coordinates requires a basic understanding of navigation using the lines of latitude and longitude.

Every single spot on the earth can be identified by a global latitude and longitude coordinate system - whoa, big words, dude! Well, let's slow down a bit. Latitude and longitude are just used to pinpoint your location. Translating the earth to a map requires some sort of agreed-upon way to describe each spot. Take a look at this map: Obviously, that is a map of the earth.
