Geography determination of coordinates on the map. Geographic coordinates and their definition on the map

Every place on earth can be identified by a global coordinate system of latitude and longitude. Knowing these parameters, it is easy to find any location on the planet. The coordinate system has been helping people in this for several centuries in a row.

Historical prerequisites for the emergence of geographical coordinates

When people began to travel long distances across deserts and seas, they needed a way to fix their position and know in which direction to move so as not to get lost. Before latitude and longitude were on a map, the Phoenicians (600 BC) and Polynesians (400 AD) used the starry sky to calculate latitude.

Quite complex devices have been developed over the centuries, such as the quadrant, the astrolabe, the gnomon, and the Arabic kamal. All of them were used to measure the height of the sun and stars above the horizon and thereby measure latitude. And if the gnomon is just a vertical stick that casts a shadow from the sun, then the kamal is a very peculiar device.

It consisted of a rectangular wooden plank measuring 5.1 by 2.5 cm, to which a rope with several equally spaced knots was attached through a hole in the middle.

These instruments determined latitude even after their invention, until a reliable method of determining latitude and longitude on a map was invented.

Navigators for hundreds of years did not have an accurate idea of the location due to the lack of a concept of the value of longitude. There was no precise time device in the world, such as a chronometer, so calculating longitude was simply impossible. Not surprisingly, early navigation was problematic and often resulted in shipwrecks.

Without a doubt, the pioneer of revolutionary navigation was Captain James Cook, who traveled through the expanses Pacific Ocean thanks to the technical genius Henry Thomas Harrison. Harrison developed the first navigational clock in 1759. Keeping accurate Greenwich Mean Time, Harrison's clock allowed sailors to determine how many hours were at a point and at a location, after which it became possible to determine longitude from east to west.

Geographic coordinate system

The geographic coordinate system defines two-dimensional coordinates based on the surface of the Earth. It has an angular unit, a prime meridian, and an equator with zero latitude. Earth conventionally divided into 180 degrees of latitude and 360 degrees of longitude. Lines of latitude are placed parallel to the equator, they are horizontal on the map. Lines of longitude connect the North and South Poles and are vertical on the map. As a result of the overlay, geographic coordinates are formed on the map - latitude and longitude, with which you can determine the position on the surface of the Earth.

This geographic grid gives a unique latitude and longitude for every position on Earth. To increase the accuracy of measurements, they are further subdivided into 60 minutes, and each minute into 60 seconds.

The equator is located at right angles to the Earth's axis, approximately halfway between the North and South Poles. At an angle of 0 degrees, it is used in geographical system coordinates as a starting point for calculating latitude and longitude on the map.

Latitude is defined as the angle between the equatorial line of the Earth's center and the location of its center. The North and South Poles have a width angle of 90. To distinguish places in the Northern Hemisphere from the Southern Hemisphere, the width is additionally provided in the traditional spelling with N for north or S for south.

The earth is tilted about 23.4 degrees, so to find the latitude at the summer solstice, you need to add 23.4 degrees to the angle you are measuring.

How to determine the latitude and longitude on the map during the winter solstice? To do this, subtract 23.4 degrees from the angle that is being measured. And in any other period of time, you need to determine the angle, knowing that it changes by 23.4 degrees every six months and, therefore, about 0.13 degrees per day.

In the northern hemisphere, one can calculate the tilt of the Earth, and therefore latitude, by looking at the angle of the North Star. At the North Pole it will be 90 from the horizon, and at the equator it will be directly ahead of the observer, 0 degrees from the horizon.

Important latitudes:

North and South polar circles, each is at 66 degrees 34 minutes north and south latitude respectively. These latitudes limit the areas around the poles where the sun does not set at the summer solstice, so the midnight sun dominates there. IN winter solstice the sun does not rise here, the polar night sets in.
Tropics are located at 23 degrees 26 minutes in the northern and southern latitudes. These latitudinal circles mark the solar zenith with the summer solstice of the northern and southern hemispheres.
Equator lies at latitude 0 degrees. The equatorial plane runs approximately in the middle of the Earth's axis between the north and south poles. The equator is the only circle of latitude that corresponds to the circumference of the earth.

Latitude and longitude on the map are important geographic coordinates. Longitude is much more difficult to calculate than latitude. The earth rotates 360 degrees a day, or 15 degrees an hour, so there is a direct relationship between longitude and the times the sun rises and sets. The Greenwich meridian is indicated by 0 degrees of longitude. The sun sets an hour earlier every 15 degrees east of it and an hour later every 15 degrees west. If you know the difference between the sunset time of a location and another famous place, then you can understand how far east or west is from it.

The lines of longitude run from north to south. They converge at the poles. And the longitude coordinates are between -180 and +180 degrees. The Greenwich meridian is the zero line of longitude, which measures the east-west direction in a system of geographic coordinates (such as latitude and longitude on a map). In fact, the zero line passes through the Royal Observatory in Greenwich (England). Greenwich meridian as zero is Starting point to calculate longitude. Longitude is specified as the angle between the center of the prime meridian of the center of the Earth and the center of the center of the Earth. The Greenwich meridian has an angle of 0, and the opposite longitude along which the date line runs has an angle of 180 degrees.

How to find latitude and longitude on a map?

Definition of exact geographical location map depends on its scale. To do this, it is enough to have a map with a scale of 1/100000, or better - 1/25000.

First, the longitude D is determined by the formula:

D \u003d G1 + (G2 - G1) * L2 / L1,

where G1, G2 - the value of the right and left nearest meridians in degrees;

L1 - distance between these two meridians;

Calculation of longitude, for example, for Moscow:

G1 = 36°,

G2 = 42°,

L1 = 252.5 mm,

L2 = 57.0 mm.

Search longitude = 36 + (6) * 57.0 / 252.0 = 37° 36".

We determine the latitude L, it is determined by the formula:

L \u003d G1 + (G2 - G1) * L2 / L1,

where G1, G2 - the value of the lower and upper nearest latitude in degrees;

L1 - distance between these two latitudes, mm;

L2 - distance from the definition point to the left nearest one.

For example, for Moscow:

L1 = 371.0 mm,

L2 = 320.5 mm.

Desired width L = 52" + (4) * 273.5 / 371.0 = 55 ° 45.

We check the correctness of the calculation, for this it is necessary to find the coordinates of latitude and longitude on the map using online services on the Internet.

We establish that the geographical coordinates for the city of Moscow correspond to the calculations:

55° 45" 07" (55° 45" 13) north latitude;
37° 36" 59" (37° 36" 93) East.

Determining location coordinates using iPhone

Accelerating the pace of scientific and technological progress by present stage led to revolutionary discoveries of mobile technology, with the help of which a faster and more accurate determination of geographical coordinates became available.

For this, there are various mobile applications. On iPhones, this is very easy to do using the Compass app.

Definition order:

To do this, click "Settings", and then - "Privacy".
Now click "Location Services" at the very top.
Scroll down until you see the compass and tap it.
If you see that it says "When used on the right side", you can start the definition.
If not, tap it and select "When using the app".
Open the Compass app and you will see your current location and current GPS coordinates at the bottom of the screen.

Determination of coordinates in an Android phone

Unfortunately, Android doesn't have an official built-in way to get GPS coordinates. However, it is possible to get Google Maps coordinates, which requires some additional steps:

Open Google Maps on Android device and find the desired definition point.
Press and hold it anywhere on the screen and drag it to Google Maps.
An informational or detailed map.
Find the Share option on the information card in the upper right corner. This will bring up a menu with the Share option.

This setup can be done in Google Maps on iOS.

This is a great way to get coordinates without the need to install any additional apps.

Video lesson "Geographical latitude and geographical longitude. Geographical coordinates» will help you get an idea of geographic latitude and geographic longitude. The teacher will tell you how to correctly determine the geographical coordinates.

Geographic latitude- the length of the arc in degrees from the equator to the given point.

To determine the latitude of an object, you need to find the parallel on which this object is located.

For example, the latitude of Moscow is 55 degrees and 45 minutes north latitude, it is written as follows: Moscow 55 ° 45 "N; New York latitude - 40 ° 43" N; Sydney - 33°52"S

Geographic longitude is determined by meridians. Longitude can be western (from 0 meridian west to 180 meridian) and eastern (from 0 meridian east to 180 meridian). Longitudes are measured in degrees and minutes. Geographic longitude can have values from 0 to 180 degrees.

Geographic longitude- length of the arc of the equator in degrees from the initial meridian (0 degrees) to the meridian of the given point.

The prime meridian is the Greenwich meridian (0 degrees).

Rice. 2. Definition of longitudes ()

To determine longitude, you need to find the meridian on which the given object is located.

For example, the longitude of Moscow is 37 degrees and 37 minutes of east longitude, it is written as follows: 37 ° 37 "E; the longitude of Mexico City is 99 ° 08" W.

Rice. 3. Geographic latitude and geographic longitude

For exact definition the location of an object on the surface of the Earth, it is necessary to know its geographic latitude and geographic longitude.

Geographical coordinates- quantities that determine the position of a point on earth's surface using latitudes and longitudes.

For example, Moscow has the following geographic coordinates: 55°45" N and 37°37" E. The city of Beijing has the following coordinates: 39°56′ N 116°24′ E The latitude value is written first.

Sometimes you need to find an object by already given coordinates, for this you must first assume in which hemispheres this object is located.

Since the time of man's entry into the seas, the need to determine longitude and latitude has been vital necessary skill person. Epochs changed, and a person became able to determine the cardinal directions in any weather. More and more new methods of determining one's position were required.

The captain of a Spanish galleon in the eighteenth century knew exactly where the ship was due to the position of the stars in the night sky. A 19th-century traveler could determine a deviation from an established route in the forest from natural clues.

Now it's the twenty-first century and many have lost the knowledge gained in geography lessons. Smartphones based on Android or iPhone can serve as a tool, but they will never replace the knowledge and ability to determine your location.

What is latitude and longitude in geography

Determination of geographical coordinates

Applications that users install on iPhone read location coordinates to provide services or data based on where the person is located. After all, if the subscriber is in Russia, then he has no reason to read sites on English language. Everything happens in the background.

While the average user will never deal with GPS coordinates, knowing how to get and read them can be valuable. In some cases, they can save a life when there is no card nearby.

In any geographic system, there are two indicators: latitude and longitude. Geodata from a smartphone shows exactly where the user is located relative to the equator.

How to determine the latitude and longitude of your location

Consider two options for determining geographic coordinates:

Via Android the simplest is the Google Maps application, perhaps the most complete collection of geographic maps in one application. After launching the application google maps location will be accurately determined. road map so that the user can get the best view of the surrounding area. The app also offers an extensive list of features, including real-time GPS navigation, traffic status and transit information, as well as detailed information about nearby places, including popular food and recreation spots, photos and reviews.
Through iPhone you don't need any third party app to view latitude and longitude data. The location is determined only with the maps application. To find out the current coordinates, just run the "maps". Touch the arrow in the upper right corner of the screen, then touch the blue dot - this is the designation of the location of the phone and the user. Next, we swipe up the screen, and now the user can see the GPS coordinates. Unfortunately, there is no way to copy these coordinates, but you can get such data.

You will need another Compass application to copy them. It is already installed on the iPhone, you can immediately use it.

To view the latitude, longitude and altitude coordinates in the Compass app, just launch and find the data at the bottom.

Determine the geographical coordinates of Moscow

For this:

We open the cards of the yandex search engine.
Enter the name of our capital "Moscow" in the address bar.
The city center (Kremlin) opens and under the name of the country we find the numbers 55.753215, 37.622504 - these are the coordinates, that is, 55.753215 north latitude and 37.622504 east longitude.

Worldwide GPS coordinates are defined by latitude and longitude according to the wgs-84 coordinate system.

In all situations, latitude is a point relative to the equator and longitude is a point relative to the meridian of the British Royal Observatory in Greenwich, UK. This defines two important parameters of online geography.

Finding the latitude and longitude of St. Petersburg

To consolidate the skill, let's repeat the same algorithm of actions, but for the Northern capital:

We open "Yandex" maps.
We prescribe the name of the northern capital "St. Petersburg".
The result of the request will be a panorama of the Palace Square and the desired coordinates 59.939095, 30.315868.

Reading GPS data or where negative numbers come from

The object's geographic positioning system has changed several times. Now, thanks to it, you can accurately determine the distance to the desired object and find out the coordinates.

The ability to show the location is a vital necessity in the search activities of the rescue services. different situations happen with travelers, tourists or extreme sportsmen. It is then that high accuracy is important, when a person is on the verge of life, and minutes count.

Now, dear reader, having such knowledge, you may have questions. There are many of them, but even from the table one of the most interesting arises - why is the number negative? Let's figure it out.

GPS when translated into Russian sounds like this - "global position system". Remember that the distance to the desired geographical object (city, village, village, and so on) is calculated according to two landmarks on the globe: the equator and the observatory in London.

At school they talked about latitude and longitude, but in yandex maps they are replaced by the left and right parts of the code. If the navigator positive values then you are heading north. Otherwise, the numbers become negative, which indicates the southern latitude.

Likewise with longitude. Positive values are east longitude and negative values are west longitude.

For example, the coordinates of the Lenin Library in Moscow are: 55°45’08.1″N 37°36’36.9″E. It reads like this: “55 degrees 45 minutes and 08.1 seconds north latitude and 37 degrees 36 minutes and 36.9 seconds east longitude” (data from Google maps).

Latitude - the angle φ between the local direction of the zenith and the plane of the equator, measured from 0 ° to 90 ° on both sides of the equator. GEOGRAPHICAL COORDINATES - latitude and longitude, determine the position of a point on the earth's surface. By default, search engine maps show coordinates in degrees from decimal with "-" signs for negative longitude.

Eastern longitudes are considered to be positive, western - negative. To fully determine the position of a point in three-dimensional space, a third coordinate is needed - the height. The main disadvantage in practical application G.S.K. in navigation is the large values of the angular velocity of this system at high latitudes, increasing up to infinity at the pole.

These coordinates are visible, for example, when laying routes from arbitrary points. The search also recognizes other formats. The most common way to find a point on the surface of the Earth (globe) is well known - using geographical coordinates called latitude and longitude. Parallels and meridians form a grid system of coordinates on the surface of the Earth, with which any place on Earth can be precisely defined.

We can think of the Earth as a sphere rotating on its own axis. The ends of the axis are the North and South Poles. The equator is a line of latitude with a value of 0°. This means that the Equator is the starting point for measuring other lines of latitude.

All lines of latitude are parallel to the equator and are sometimes also called parallels. The equator divides the Earth into northern and southern hemispheres. Northern latitudes are positive and southern latitudes are negative values. In the end, it was decided that the line of zero longitude passes through the Greenwich Laboratory, located in England on the eastern outskirts of London. This line is also called the zero or Greenwich meridian.

What is longitude?

Each circle line can be divided into degrees with minutes and seconds. A degree of longitude is 1/360 of the equator. The interval between the 39th and 40th parallels is 1° of latitude. The interval between the 175th and 176th meridians is 1° of longitude. Thus, the complete record of the geographical coordinates of the Ngauruhoe volcano: 39° 07′ S, 175° 37′ E. 39 degrees, seven minutes south latitude.

What is latitude?

A second of latitude is approximately 0.03 kilometer, or approximately 30 meters. At the equator it is about 111 kilometers, the same distance as a degree of latitude. The size of longitude gradually decreases and tends to zero as the meridians converge at the Earth's poles. Thus, at a latitude of 45°, a degree of longitude is approximately 79 kilometers. As degrees of longitude change in size, minutes and seconds of longitude also change, decreasing in size towards the poles.

Almost all globes have lines of parallels and meridians. Also, many globes have a so-called meridian arc, which serves not only to hold the sphere of the globe on a stand, but also helps to determine geographical coordinates. There is a degree scale on the meridian arc (see photo). This scale is used to determine latitude. If there is no degree scale on the meridian arc, then there is such a scale on the prime meridian (Greenwich) and on the international date line (meridian 180°). But longitude is determined by the equator.

If this point is above the equator, then it will be the northern latitude, if below the equator - south latitude. Then determine the longitude. To do this, you need to look at the numerical value of the point of intersection of the equator and the meridian arc. This value must be viewed on the equator scale. It combines the beauty of levitation and modern technology.

An electromagnetic globe is a wonderful gift and souvenir for you and your friends. The geographical latitude of points lying in the northern hemisphere (northern latitude) is considered to be positive, the latitude of points in the southern hemisphere is negative. It is customary to speak of latitudes close to the poles as high, and those close to the equator as low. The choice of the zero meridian is arbitrary and depends only on agreement.

Within geographical envelope usually used is ‘altitude above sea level’, measured from the level of a “smoothed” surface - the geoid. Such a system of three coordinates turns out to be orthogonal, which simplifies a number of calculations. The orientation of the axes in the geographic coordinate system (GCS) is selected by the algorithm. The orientation of the trihedron is XYZ, due to the rotation of the earth and the movement of the vehicle, it constantly shifts with angular velocities.

There are no uniform rules for recording coordinates. All GPS navigators and major mapping projects on the Internet work in this coordinate system. The generally available accuracy when working with geographic coordinates is 5 - 10 meters on the ground. Coordinates are angular quantities and are expressed in degrees. Geographic coordinates will appear in the search bar of the map (as well as in the panel on the right).

A panel with the address and geographic coordinates will appear below the search bar. The current location is usually captured as a waypoint, from which coordinates can later be read.

At the same time, the numerical values of the coordinates remain available (they can be seen in the search bar of the map that opens via the link). Please note that point markers displayed on the map are tied to roads, and their position corresponds to the entered coordinates only approximately. Recording forms can be simply converted one into another (1 degree = 60 minutes, 1 minute = 60 seconds).

On Google maps and Yandex maps, latitude first, then longitude (until October 2012, the reverse order was adopted on Yandex maps: first longitude, then latitude). Longitude - the angle λ between the plane of the meridian passing through the given point, and the plane of the initial zero meridian, from which the longitude is counted.

Geographic latitude and longitude are plotted on a world map. With their help, it is easy to determine the location of the object.

A geographical map of the world is a reduced projection of the earth's surface on a plane. Continents, islands, oceans, seas, rivers, as well as countries, big cities and other objects.

On the geographical map a grid has been drawn.
On it you can see clearly information about the continents, seas and oceans, and the map allows you to create an image of the relief of the world.
Using a geographical map, you can calculate the distance between cities and countries. It is also convenient to search for the location of land and ocean objects.

The shape of the Earth is like a sphere. If you need to determine a point on the surface of this sphere, then you can use the globe, which is our planet in miniature. But there is the most common way to find a point on Earth - these are geographical coordinates - latitude and longitude. These parallels are measured in degrees.

Geographic map of the world with latitude and longitude - photo:

The parallels that are drawn along and across the entire map are latitude and longitude. With their help, you can quickly and easily find any place in the world.

The geographical map of the hemispheres is convenient for perception. Africa, Eurasia and Australia are depicted on one hemisphere (eastern). Another - western hemisphere- North and South America.

Even our ancestors were engaged in the study of latitude and longitude. Even then there were maps of the world, not similar to modern ones, but with their help you can also determine where and what object is located. A simple explanation of what the geographic latitude and longitude of an object on a map is:

Latitude is a coordinate value in the system of spherical numbers that defines a point on the surface of our planet relative to the equator.

If the objects are located in the northern hemisphere, then the geographic latitude is called positive, if in the southern hemisphere - negative.
South latitude - the object is moving from the equator towards the North Pole.
North latitude - the object is moving towards South Pole from the equator.
On a map, latitudes are lines that are parallel to each other. The distance between these lines is measured in degrees, minutes, seconds. One degree is 60 minutes and one minute is 60 seconds.
The equator is zero latitude.

Longitude is a coordinate value that determines the location of the object relative to the zero meridian.

This coordinate allows you to find out the location of the object relative to the west and east.
Lines of longitude are meridians. They are located perpendicular to the equator.
The zero point of longitude in geography is the Greenwich Laboratory, which is located in east London. This line of longitude is called the Greenwich meridian.
Objects that are to the east of the Greenwich meridian are the east longitude area, and those to the west are the west longitude area.
East longitudes are considered positive, and west longitudes are considered negative.

With the help of the meridian, such a direction as north-south is determined, and vice versa.

Latitude on a geographical map is measured from the equator - this is zero degrees. At the poles - 90 degrees of geographical latitude.

From what points, what meridian is the geographic longitude measured?

Longitude on a geographical map is measured from Greenwich. The prime meridian is 0°. The farther away from Greenwich an object is, the greater its longitude.

To determine the location of an object, you need to know its geographical latitude and longitude. As mentioned above, latitude shows the distance from the equator to a given object, and longitude shows the distance from Greenwich to the desired object or point.

How to measure, find out the geographical latitude and longitude on the world map? Each parallel of latitude is indicated by a specific number - a degree.

Meridians are also indicated by degrees.

Measure, find out the geographical latitude and longitude on the world map

Any point will be located either at the intersection of the meridian and the parallel, or at the intersection of intermediate indicators. Therefore, its coordinates are indicated by specific indicators of latitude and longitude. For example, St. Petersburg is located at the following coordinates: 60° north latitude and 30° east longitude.

As mentioned above, latitude is parallels. To determine it, you need to draw a line parallel to the equator or a nearby parallel.

If the object is located on the parallel itself, then it is easy to determine its location (it was described above).
If the object is between parallels, then its latitude is determined by the nearest parallel from the equator.
For example, Moscow is located north of the 50th parallel. The distance to this object is measured along the meridian and it is equal to 6 °, which means that the geographical latitude of Moscow is 56 °.

An illustrative example of determining the geographical coordinates of latitude on a world map can be found in the following video:

Video: Geographic latitude and geographic longitude. Geographical coordinates

To determine geographic longitude, you need to determine the meridian on which the point is located, or its intermediate value.

For example, St. Petersburg is located on the meridian, the value of which is 30°.
But what if the object is located between the meridians? How to determine its longitude?
For example, Moscow is located east of 30° east longitude.
Now add the number of degrees along the parallel to this meridian. It turns out 8 ° - it means that the geographical longitude of Moscow is 38 ° east longitude.

Another example of determining the geographic coordinates of longitude and latitude on a world map in a video:

Video: Finding latitude and longitude

All parallels and meridians are indicated on any map. What is the maximum value of geographic latitude and longitude? Highest value geographic latitude - 90 °, and longitude - 180 °. Most small value latitude is 0° (Equator), and the smallest value of longitude is also 0° (Greenwich Mean Time).

Geographic latitude and longitude of the poles and equator: what is it?

The geographical latitude of the points of the earth's equator is 0 °, North Pole+90°, South -90°. The longitude of the poles is not determined, since these objects are located on all meridians at once.
