What goes first Longitude or Latitude?

Answer 1

Latitude first, Longitude next. Why? By convention, it's the IMO standard. There are no "landmarks" when out on the high seas, so a universally understandable method of reporting location is a must, for both those seeking help and those willing/able to provide help. Background: Beginning in 1958 a world-wide effort to simplify SAR operations on the high seas took effect. Called AMVER, it's a voluntary, computer-based, global position reporting system for ships that rescue center(s) might contact in an emergency. {The closest ship will be contacted and asked to help.} To avoid confusion, a standard was developed for all ships to report their specifics: Who, what, where, speed, course, medical personnel available, and more. Since SAR operations might be cnducted over land or on the seas, and might involve different military units as well as civilial resources (ALL available resources are contacted when the cry for help goes out) an army helicopter pilot needs clear/understandable communications with a Coast Guard vessel, Naval helicopter or a police department - and it's sometimes a situation where two or more countries using different languages might be involved. Having an agreed standard removes confusion. Check the Related Link and you'll see the form used for reporting. IMO = International Maritime Organization SAR = Search And Rescue AMVER = Automated Mutual assistance VEssel Reporting system. source: http://www.amver.com/imostandard.htm

Answer 2

Usually, when writing a location using a GPS-type notation, the northern or Southern Hemisphere is noted first (latitude), then the eastern or Western Hemisphere (longitude).



Here are examples:

• 49N, 127W
• 77S, 177W
• 62N, 0E

Answer 3

Latitude is given first, as in 27°N 112°E.
=====================
-- If you're communicating the coordinates to people, then it really
doesn't matter, just as long as you clearly indicate which is which.

-- If the coordinaters will wind up in a computer, then you must be careful
to list them the way the computer expects them to be presented, which is
usually latitude first.

Answer 4

I have seen them written both ways, with latitude first and with longitude first. But you can always tell, because if the direction is North or South, it is latitude. If the direction is east or west, it's longitude.

Answer 5

Yes!

Just like co-ordinates on a graph, x always comes before y.

Latitude are horizontal lines (x) and longitude are vertical lines (y).

So : (x,y)

Answer 6

Latitude is typically written first. But it makes absolutely no difference, as long as

you clearly identify which is which when you give a set of coordinates.

Answer 7

Latitude generally comes first, but I have seen it written with longitude first. As long as you have labeled the directions (north or south, east or west) it really doesn't matter.

Answer 8

Latitude.

Answer 9
