Note that negative latitudes represent the southern hemisphere, and negative longitudes represent the western hemisphere. … In our example, 0.3069° times 60 gives us 18.42 minutes latitude, while 0.8583° times 60 gives us 51.50 minutes of longitude.
Why is longitude in negative?
If the number is negative, it represents south of the Equator. The line of longitude is read as 2 degrees (2), 10.4418 minutes (10.4418) east. The coordinate for the line of longitude represents east of the Prime Meridian because it is positive. If the number is negative, it represents west of the Prime Meridian.
How do you read a negative latitude and longitude?
“A negative number for latitude, such as -7.48° (if it’s negative, the minus is always shown), is a SOUTH latitude!” “And for longitude, if there’s no E or W, and if the number is positive (such as 128.3425° or +128.34°), then the longitude is EAST.
Can longitude values negative?
Each line of longitude runs north and south and measures the number of degrees east or west of the Prime Meridian. Values range from positive 180 to negative 180 degrees.
How do you know if longitude is negative?
Positive longitude is east of the prime meridian, while negative longitude is west of the prime meridian (a north-south line that runs through a point in England). Those values you give describe a point somewhere in Idaho (north of the equator and west of the prime meridian).
What is positive and negative longitude?
Positive longitudes are east of the Prime Meridian; negative longitudes are west of the Prime Meridian. Latitude and longitude are usually expressed in that sequence, latitude before longitude.
Is north positive or negative longitude?
Latitude/longitude coordinates follow a regular Cartesian system starting from the Equator and the Prime Meridian. Positive coordinates are to the right (east) and up (north).
Can degrees minutes seconds be negative?
1 Answer. If possible, stay in decimal degrees and eschew DMS, but sounds like you must. Negative minutes and Negative seconds seems the most appropriate path, placing the negative on the degrees, then the minutes and then the seconds.
Does latitude go first?
Handy tip: when giving a co-ordinate, latitude (north or south) always precedes longitude (east or west). Latitude and longitude are divided in degrees (°), minutes (‘) and seconds (“). There are 60 minutes in a degree and 60 seconds in a minute (similar to measuring time).
Is east longitude positive or negative?
For calculations, the West/East suffix is replaced by a negative sign in the western hemisphere. The international standard convention (ISO 6709)—that East is positive—is consistent with a right-handed Cartesian coordinate system, with the North Pole up.
In which direction latitude of line is negative?
In which direction latitude of the line is negative? Explanation: The latitude of the line is negative when measured southward. It is termed as southing.
Is y a latitude?
Latitude is the Y axis, longitude is the X axis. Since latitude can be positive and negative (north and south of the Equator), and longitude can be as well (negative west of Greenwich and positive eastward) when the -180 to +180 longitude system is use.
Why are longitudes negative in north America?
Latitude/Longitude Formats
Note that negative latitudes represent the southern hemisphere, and negative longitudes represent the western hemisphere. The fractional portion of decimal degrees are instead represented as the number of “minutes” between 0 and 60.
How do you read latitude and longitude?
When outlining the coordinates of a location, the line of latitude is always given first followed by the line of longitude. Therefore, the coordinates of this location will be: 10°N latitude, 70°W longitude. The line of latitude is read as 41 degrees (41°), 24 minutes (24′), 12.2 seconds (12.2”) north.
What is latitude or longitude?
Both longitude and latitude are angles measured with the center of the earth as an origin. … A longitude is an angle from the prime merdian, measured to the east (longitudes to the west are negative). Latitudes measure an angle up from the equator (latitudes to the south are negative).
What are longitudes called?
Longitudes are known as meridians because in Geographical sense, meridians are great circles which are not parallel to each other but intersect each other at the North and the South Poles.
Where is the Prime Meridian?
The prime meridian is arbitrary, meaning it could be chosen to be anywhere. Any line of longitude (a meridian) can serve as the 0 longitude line. However, there is an international agreement that the meridian that runs through Greenwich, England, is considered the official prime meridian.
What are examples of longitude?
An example of longitude is that New York City is at 74° degrees west and local time is 5 hours less than Greenwich mean time. Angular distance measured west or east of the prime meridian.
How many latitudes are there?
There are 180 latitudes in total, which is 90 degrees south and 90 degrees north. These are circles that are concentric to the Equator. There are 360 longitudes in total, 180 degrees eastand 180 degrees west of the Greenwich line.
Can you round latitude and longitude?
So, as you can see from the table below, a lat/long rounded up to a single decimal place can accurately identify a country or region, whereas rounded up to two could identify a large city or district. But five decimal places can accurately hone in on an individual tree, and six can identify a person.
Can you have negative decimal degrees?
In Decimal Degrees format, the latitude and longitude coordinates are represented as positive or negative decimal values.
How was longitude discovered?
Eratosthenes in the 3rd century BCE first proposed a system of latitude and longitude for a map of the world. … He also proposed a method of determining longitude by comparing the local time of a lunar eclipse at two different places, to obtain the difference in longitude between them.
Is longitude horizontal?
Hemisphere – one half of the planet Page 2 Latitude – horizontal lines on a map that run east and west. They measure north and south of the equator. Longitude – the vertical lines on a map that run north and south. They measure east and west of the Prime Meridian.

Is the latitude up or down?
Lines of latitude run east and west. Lines of latitude run horizontally around the Earth and tell you how far north or south you are from the Equator. … As the rungs go up and down a ladder, so do the lines of latitude.
Is north latitude or longitude?
If you take a look at a map or globe of the world, you may notice lines running east-west and north-south. The lines run east-west are known as lines of latitude. The lines running north-south are known as lines of longitude.
When measuring toward northward latitude is negative a true b false?
2. When measured towards southward, latitude is negative. Explanation: Depending on the quadrant in which it lies, the latitude and departure were given signs. For latitude, it is taken as positive in north and negative towards south direction.
What is closed traverse?
A closed traverse is a series of connected lines whose lengths and bearings are measured off these lines (or sides), which enclose an area. A closed traverse can be used to show the shape of the perimeter of a fire or burn area.
What is said about that traverse when total latitude and departure are zero?
The process of adjusting the latitudes and departures to make the algebraic sum of latitudes or departures to zero is called the balancing of errors. … By this rule, total error in latitude (or) departure is distributed in proportion to lengths of traverse legs.
What axis represents latitude?
Latitude is the Y axis, longitude is the X axis. Since latitude can be positive and negative (north and south of the Equator), and longitude can be as well (negative west of Greenwich and positive eastward) when the -180 to +180 longitude system is use.
How do I enter Lat Long in Google Earth?
- Open Google Earth.
- In the Search box in the left-hand panel, enter coordinates using one of these formats: Decimal Degrees: such as 37.7°, -122.2° …
- Google Earth zooms into that location and coordinates will be displayed in the lower right corner.
How many longitudes are there?
To measure longitude east or west of the Prime Meridian, there are 180 vertical longitude lines east of the Prime Meridian and 180 vertical longitude lines west of the Prime Meridian, so longitude locations are given as __ degrees east or __ degrees west.
