Questions tagged [latitude-longitude]

Angular geographic coordinates that specifying the north-south and east-west positions of locations.

This tag indicates questions involving issues with or concepts about latitude, longitude, or both.

This tag should not be used for referencing lat/lon GmbH software

"In geography, the latitude of a location on the Earth is the angular distance of that location south or north of the equator" (Wikipedia). It can also be one of many not-quite-equivalent determinations, such as the angle made between "straight up" and the earth's equatorial plane (the "astronomical latitude").

Why latitude/longitude and not other way round?

When you google "latitude/longitude" you get 10 times more results than "longitude/latitude". This I find very confusing as "x/y" seems 20 times more common than "y/x". But on a map Latitude is on the Y axis and longitude on the X. Any…

Representing degrees between -1 and 0 in Degrees:Minutes:Seconds

When representing latitude and longitude in degrees, minutes and seconds, with -180 <= D <= 180 (or -90 and 90) 0 <= M < 60 (0 if D is at an extreme) 0 <= S < 60 (0 if D is at an extreme) How can values between -1 degree and 0 degrees be…

What to use to divide longitude on smaller parts than time zones?

I have a database of earth's grid, I have consolidated elements from 1152x576 to 360°x180° and then those degrees into geographical zones and time zones so I get 5(6) geographical zones (N/S frigid, N/S temperate, (N/S) torrid) and ~24 time zones…

Converting DMS to decimal degrees, what precision?

I'm working on a piece of software that converts Lat & Long from DMS (35° 19′ 20″ N) to decimal degrees. At the moment, the code creates number with 16 digits after the decimal point, which seems absurd. Since we never have more than 2 digits for…

Shortest and longest amount of numbers that latitude and longitudinal coordinates may have?

What is the shortest and longest amount of numbers that latitude and longitudinal coordinates may have? For instance i know that London is 51.5072 0.1275. So the first value is 6 numbers and the second is 4 (or 5 depending on how you look at it).
