How are latitude and longitude measured?

Answer 1

The lines aren't measured at all, except possibly in the process of printing the map.

It's the longitude that needs to be measured, and lines are often printed on maps

in order to make that job easier. Longitude is an angle, so it's described in angle units,

most commonly in degrees.

If you see a line on a map, every point on the 'line' has the same longitude, so there's

nothing on the line to measure.

Answer 2

These lines are imaginary and run east-west as circles parallel to the equator. Latitude used with Longitude serve to record places on the Earth. The units are in degrees (and minutes and seconds). Oo is the Equator, and the Poles are at 90o.

The position is determined either by GPS satellite methods, or by astronomy methods, or by Surveyors.

Answer 3

They are measured in degrees, and they are measured in such a way that each line of longitude crosses 180 degrees of latitude, and each line of latitude crosses 360 degrees of longitude. I am considering that each line of longitude extends from pole to pole and intersects the equator once. There is a corresponding line of longitude 'opposite' a given line. It is the line of longitude that would complete a circle that goes from pole to pole. But the two sections of this circle are of two different measures of longitude and so as lines of longitude they are distinct.

The Prime Meridian, or the Greenwich Meridian, is zero degrees longitude. It extends from pole to pole going exactly through the observatory in Greenwich, England. From there, degrees west extend to the west, across the Atlantic, the Americas and most of the Pacific, until you reach 180 degrees longitude, the International Date Line. This is the line 'opposite' the Prime Meridian. You don't have to specify 180 degrees east longitude or west longitude, because they are the same line. Degrees east longitude begin at the Prime Meridian and continue east across Europe, Africa, Asia and Australia until they reach 180 degrees, the International Date Line.

Lines of latitude, the parallels, mark the same latitude wherever you are on a given parallel. Zero degrees latitude is the equator. Degrees north latitude move, not surprisingly, northward from the equator until you reach 90 degrees north latitude, the north pole. The south latitudes extend to 90 degrees south, the south pole.

So if you travel any line of longitude along with its 'opposite' line of longitude on the other side of the planet, you will cover 360 degrees of latitude. No matter what line(s) of longitude you travel, you will go very nearly exactly the same distance. If you stay on any one line of latitude and travel its length, you will cover 360 degrees of longitude, but your journey could be anywhere from about 25,000 miles at the equator, to an arbitrarily short stroll around one of the poles.

Answer 4

Latitude and longitude are measured in degrees, minutes, and seconds. Latitude measures how far north or south a location is from the equator, while longitude measures how far east or west a location is from the Prime Meridian, which runs through Greenwich, England. Latitude ranges from 0° at the equator to 90° at the North and South Poles, while longitude ranges from 0° at the Prime Meridian to 180° east or west.
