3 Ways to Determine Latitude and Longitude [1]
wikiHow is a “wiki,” similar to Wikipedia, which means that many of our articles are co-written by multiple authors. To create this article, 25 people, some anonymous, worked to edit and improve it over time.
There are several ways to find your latitude and longitude – some of which require many more resources than others. Find your coordinates with a map and protractor once you understand latitude and longitude.
Since the earth is round, distance from the equator is measured in angular degrees with the equator being 0 degrees and the northernmost point — the North Pole — being at 90 degrees. The southernmost point — the South Pole — is also at 90 degrees.[1] X Research source

DIY: Measuring latitude and longitude [3]
This content is associated with The Open University’s Geography courses and qualifications.. To pinpoint your position on a map of the world you need to work out your co-ordinates, known as latitude and longitude
Lines, or parallels, are drawn around the Earth at intervals. The North Pole is assigned the latitude 90º north and the South Pole latitude 90º south.
The line of longitude corresponding to 0º, which passes through Greenwich in London, is called the Prime (or Greenwich) Meridian. Longitude lines run along the Earth’s surface in a north–south direction, and unlike latitude lines, they divide the globe into segments like those of an orange, rather than regular strips.
GSP 270: Latitude and Longitude [4]
When we describe the Earth in spherical coordinates it is called Geographic, or Un-projected. The most common system for locating points on the earth is with “Longitudes” and “Latitudes”
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).
You’ve seen lines running across maps your whole life and may not have noticed them. The lines running North to South are called “Meridians” or “lines of longitude” (Figure 2), while the lines running East to West are called “Parallels” or “lines of latitude” (Figure 3).
How to determine your coordinates (latitude and longitude) without GPS [5]
Being a mobile star dome, we travel all over the UK to bring space science to our learners. Luckily, there are sat navs to show us directions and seamlessly guide us through busy traffic, road closures and congestion
Today’s challenge is to learn to calculate the coordinates the old-fashioned way. On Earth we specify one’s position using two coordinates: latitude and longitude
Latitude lines, or parallels, run horizontally and parallel to the equator. Latitude tells us how far North (values 0 to 90 degrees N) or South (values 0 to 90 degrees S) we are from the equator.
6.10 Latitude & Longitude [6]
Latitude and longitude are measuring lines used for locating places on the surface of the Earth. They are angular measurements, expressed as degrees of a circle
The symbol for minutes is (´) and for seconds is (“).. Latitude lines (called parallels) circle the planet’s surface in lines parallel to the equator, which lies halfway between the North and South poles
Longitude lines (called meridians) run north and south and circle the planet from pole to pole. Each line is identified by the number of degrees east or west from a starting point at Greenwich, England, known as the prime meridian
Where on earth are you? A beginners guide to longitude [7]
For as long as humans have been exploring, we have sought reliable methods to navigate our way across the Earth. Until the invention of an accurate sea clock by carpenter and clockmaker John Harrison in the 18th century, there was no dependable technique to measure a ship’s longitude – its east or west position at sea – especially when the ship’s navigator could not sight landmarks or celestial markers due to the weather.
This meant that ships could miss their supply points, sail past safe harbours or, worse, become wrecked upon rocks or reefs they didn’t realise they were sailing into.. To chart your position there are two co-ordinates you need:
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).
Determining Your Site’s Latitude and Longitude [8]
If you have adequate reception at your site, you can use your phone to determine your latitude and longitude.. – Android: Open Google Maps; it will zoom to your approximate location
If you don’t have Google Maps, you can install a free GPS app before heading to your site.. If you don’t have adequate cellular reception at your site to use the methods above, you can determine your site’s latitude and longitude when you get back to your computer.
See step-by-step instructions on WikiWatershed.org.. If you are not sharing your data on Monitor My Watershed (please do!), you can use Google Maps to determine your site’s latitude and longitude
2.1 Latitude and Longitude – Introduction to Oceanography [9]
Any point on Earth can be defined by the intersection of its lines of latitude and longitude. is measured as the angle from the equator, to the Earth’s center, to your position on the Earth’s surface (Figure2.1.1)
Thus the poles are referred to as high latitude, while the equatorial region is considered low latitude. Lines of equal latitude are always the same distance apart, and so they are called parallels of latitude; they never converge
One degree of latitude is divided into 60 minutes (‘). One minute of latitude equals one , which is equal to 1.15 land miles (1.85 km)
Units of Longitude and Latitude [10]
The demarcation of the longitude coordinate is done with lines going up and down are called the meridians. Longitude ranges from 0° to 180° East and 0° to 180° West
The zero point of longitude is defined as a point in Greenwich, England called the Prime Meridian. (Why Greenwich of all places?) 180° away from the Prime Meridian is the line called the International Date Line
The demarcation of the latitude coordinate is done with circles on the globe parallel to the equator. These parallel circles, fittingly enough, are called parallels of latitude
Rough Science . Latitude and Longitude Challenge [11]
Measuring latitude using the sun can only be done at noon, when the sun. a watch or radio) place a stick at the southernmost end of your north-south
shadow cast by the stick crosses the north-south line, it’s noon.. As soon as it’s noon, align the sighting nails on the quadrant’s aiming
shadows, so move the end of the beam up or down so that these two shadows. When the shadows coincide, the beam is aimed exactly at the sun
Understanding Latitude and Longitude [12]
numbers, people can communicate about location no matter what language. A global address is given as two numbers called coordinates.
Using Lat/Long is different from using a street address. a specific street address, Lat/Long works with a numbered grid system,
and vertical coordinates; or, to say it another way, the “intersection”. Latitude and Longitude lines are a grid map system too
Latitude and longitude | Definition, Examples, Diagrams, & Facts [13]
Our editors will review what you’ve submitted and determine whether to revise the article.. – Equator parallel geographic latitude geocentric latitude pluviometric equator
Latitude is a measurement on a globe or map of location north or south of the Equator. Technically, there are different kinds of latitude—geocentric, astronomical, and geographic (or geodetic)—but there are only minor differences between them
Given in degrees, minutes, and seconds, geocentric latitude is the arc subtended by an angle at Earth’s centre and measured in a north-south plane poleward from the Equator. Thus, a point at 30°15′20″ N subtends an angle of 30°15′20″at the centre of the globe; similarly, the arc between the Equator and either geographic pole is 90° (one-fourth the circumference of Earth, or 1/4 × 360°), and thus the greatest possible latitudes are 90° N and 90° S

Latitude and Longitude [15]
People split the Earth into lines of latitude and longitude to help with navigation. Latitude lines are lines around the Earth moving from north to south, and a person’s latitude determines how far north or south they are in degrees
Longitude lines, or meridians, circle the Earth from east to west, and a person’s longitude determines how far east or west they are in degrees. The meridian that passes through Greenwich, in London, is set at 0° longitude for historical reasons.
You can do this by placing a stick in the ground and looking at the angle of its shadow.. At the equator, the Sun will be perpendicular to the ground but as you move away, the Sun will seem tilted because you are on a surface that is tilted
Traditional Ways of Knowing: Estimating Latitude [16]
A diagram depicts the relationship between the North Star, Earth’s axis, and its orbit (diagram is not drawn to scale). If you can locate the North Star, the angle between the height of the North Star when it reaches its zenith (highest point) in the sky and the horizon indicates your location in degrees latitude
At the equator, an observer will see that the North Star is located almost exactly at the horizon. Thus, at the equator, the angle between the horizon and the North Star is zero degrees, indicating the observer is at zero degrees latitude
A diagram depicts the relationship between the North Star, Earth’s axis, and its orbit (diagram is not drawn to scale). To determine your latitude without any instruments, stretch your hand out in front of you as far as it will go
Longitude points using haversine formula in JavaScript [17]
This page presents a variety of calculations for latitude/longitude points, with the formulas and code fragments for implementing them.. All these formulas are for calculations on the basis of a spherical earth (ignoring ellipsoidal effects) – which is accurate enough* for most purposes… [In fact, the earth is very slightly ellipsoidal; using a spherical model gives errors typically up to 0.3%1 – see notes for further details].
|where||φ is latitude, λ is longitude, R is earth’s radius (mean radius = 6,371km);. note that angles need to be in radians to pass to trig functions!
Note in these scripts, I generally use lat/lon for latitude/longitude in degrees, and φ/λ for latitude/longitude in radians – having found that mixing degrees & radians is often the easiest route to head-scratching bugs…. The haversine formula1 ‘remains particularly well-conditioned for numerical computation even at small distances’ – unlike calculations based on the spherical law of cosines
History of longitude [18]
The history of longitude describes the centuries-long effort by astronomers, cartographers and navigators to discover a means of determining the longitude of any given place on Earth. The measurement of longitude is important to both cartography and navigation
Finding an accurate and practical method of determining longitude took centuries of study and invention by some of the greatest scientists and engineers. Determining longitude relative to the meridian through some fixed location requires that observations be tied to a time scale that is the same at both locations, so the longitude problem reduces to finding a way to coordinate clocks at distant places
Later methods used the telegraph and then radio to synchronize clocks. Today the problem of longitude has been solved to centimeter accuracy through satellite navigation.
Latitude, Longitude and Coordinate System Grids [19]
Here’s how you can remember latitude and longitude:. Latitude lines run east-west and are parallel to each other
And its X-coordinates are between -180 and +180 degrees.. Latitude and longitude coordinates make up our geographic coordinate system.
The field of study that measures the shape and size of the Earth is geodesy. Geodesists use coordinate reference systems such as WGS84, NAD27, and NAD83
Latitude vs Longitude – Difference and Comparison [20]
The latitude specifies a location’s distance north or south of the equator. The longitude specifies the location’s distance east or west from an imaginary line connecting the North and South Poles, called the Prime Meridian.
Latitudes, represented by the Greek letter phi (Φ), are called parallels and longitudes, denoted by the Greek letter lambda (λ), are called meridians.. |Direction||East-west, parallel to the equator||North-south; converging at the poles and widest at the equator|
|Denoted by||Greek letter phi (Φ)||Greek letter lambda (λ)|. |Hemisphere||All locations along a common latitude fall in the same hemisphere of the earth (northern or southern)||Locations along a common longitude may be in different hemispheres.|
Discover coordinates or search by latitude & longitude [21]
To search for a place, enter the latitude and longitude GPS coordinates on Google Maps. You can also find the coordinates of the places you previously found.Besides longitude and latitude, you can use plus codes to share a place without an address.
– Degrees and decimal minutes (DMM): 41 24.2028, 2 10.4418. You can find your latitude and longitude in decimal format at the top.
To format your coordinates so they work in Google Maps, use decimal degrees in the following format:. – List your latitude coordinates before longitude coordinates.

Latitude and Longitude Finder on Map Get Coordinates [23]
Latitude and Longitude are the units that represent the coordinates at geographic coordinate system. To make a search, use the name of a place, city, state, or address, or click the location on the map to find lat long coordinates.
Just like every actual house has its address (which includes the number, the name of the street, city, etc), every single point on the surface of earth can be specified by the latitude and longitude coordinates. Therefore, by using latitude and longitude we can specify virtually any point on earth.
The latitude is specified by degrees, starting from 0° and ending up with 90° to both sides of the equator, making latitude Northern and Southern. The longitude has the symbol of lambda and is another angular coordinate defining the position of a point on a surface of earth
