![]() ![]() Once you learn how to plot latitude and longitude on a map, the possibilities are endless. What Can You Do With Latitude and Longitude Coordinates? You can format the number pairs as degrees of decimals (called decimal degrees) or expressed in degree minutes seconds (DMS). Number pairs separated by a comma often represent latitude and longitude coordinates. Plot 51.500833 latitudes and -0.141944 longitude, and you’ll arrive at Buckingham Palace, which is very near the Greenwich Observatory. Using a world map or a globe, for example, and plotting zero latitudes (0 degrees) and -78.455833 longitude (-78.455833 degrees or -78 degrees and 456 minutes), you’ll arrive at the Mitad del Mundo in Quito, Ecuador. The latitude always comes first, and the longitude comes second. Using these imaginary lines, you can plot latitude and longitude number pairs - or coordinates -on a map. It’s also the universally accepted method to do so. Plot points on a map using latitude and longitude because it’s the most accurate way to find exact locations. Why Plot Points on a Map Using Latitude and Longitude Coordinates Longitude, therefore, measures the distance east and west of the prime meridian. Meridians to the west range from -1 to -180 degrees. Meridians east of the prime meridian go from one to 180 degrees. ![]() Longitude lines run around the earth from the North pole to the South pole and parallel to the prime meridian. The Greenwich Observatory in London is the zero longitude or the prime meridian. On the other hand, imaginary longitude lines have no natural zero reference point. Parallels below the equator (towards the South Pole) are from -1 to -90 degrees. Latitude lines, or parallels, that run above the equator (towards the North Pole) go from one to 90 degrees. The central reference point is the equator - the zero latitude. ![]() Now let’s apply this to how to plot points on a map.īecause the world is spherical and not flat, imaginary latitude lines encircle the globe east-west and parallel to each other. In that case, you already understand latitude (represented by the Y-axis) and longitude (represented by the X-axis). Every vertical graph line corresponds to a point on the Y. Each horizontal graph line corresponds to a point on the X-axis. If you recall, the axes of this graph were X and Y axes. Here’s another way to understand that basic description of lat and long.ĭo you remember algebra from your school days? A teacher would show you a graph and ask you to plot points to form a line. They’re measurements on a map or globe used to determine location coordinates. Latitude and longitude (sometimes shortened at lat/long) are imaginary graph lines covering the earth’s surface. Keep reading for tips on how to do this and how to use online plotting tools. If you want to make maps, you’ll need to know how to find coordinates and plot points using these lines. That’s why knowing how to plot latitude and longitude remains invaluable to cartographers. However, even modern geolocation methods still use longitude and latitude coordinates to craft maps. Advanced tools, such as satellites, GPS, aerial photography, sensors, and other data-driven technologies, assist map-making these days. txt file is free by clicking on the export iconĬite as source (bibliography): Points Plotter on dCode.Back when much of the world was still unexplored, map making, or cartography, was tedious and difficult.
