Determining latitude and longitude on a map?
On the page you can quickly determine coordinates on the map - find out the latitude and longitude of the city. Online search for streets and houses by address, using GPS, to determine coordinates on a Yandex map, how to find a location - described in more detail below.
Determining the geographic coordinates of any city in the world (find out latitude and longitude) using an online map from the Yandex service is actually a very simple process. You have two convenient options, let’s take a closer look at each of them.
Fill out the form: Rostov-on-Don Pushkinskaya 10 (with the help and if you have the house number, the search will be more accurate). In the upper right corner there is a form for determining coordinates, which contains 3 precise parameters - the coordinates of the mark, the center of the map and the zoom scale.
After activating the “Find” search, each field will contain the necessary data - longitude and latitude. Look at the “Center of the map” field.
Second option: In this case it’s even simpler. Interactive world map with coordinates contains a marker. By default, it is located in the center of Moscow. You need to drag the label and place it on the desired city, for example, determine the coordinates on. The latitude and longitude will automatically match the search object. Look at the “Mark Coordinates” field.
When searching for the desired city or country, use the navigation and zoom tools. By zooming in and out +/-, and also moving the interactive map itself, it is easy to find any country or search for a region on the world map. This way you can find the geographic center of Ukraine or Russia. In the country of Ukraine, this is the village of Dobrovelichkovka, which is located on the Dobraya River, Kirovograd region.
Copy the geographic coordinates of the center of Ukraine urban settlement. Dobrovelychkovka — Ctrl+C
48.3848,31.1769 48.3848 north latitude and 31.1769 east longitude
Longitude +37° 17′ 6.97″ E (37.1769)
Latitude +48° 38′ 4.89″ N (48.3848)
At the entrance to the urban settlement there is a sign announcing this interesting fact. It will most likely be uninteresting to examine its territory. There are much more interesting places in the world.
How to find a place on the map using coordinates?
Let's consider the reverse process, for example. Why do you need to determine latitude and longitude on a map? Let's say you need to determine the exact location of the car on the diagram using GPS navigator coordinates. Or a close friend will call on a weekend and tell you the coordinates of his location, inviting you to join him hunting or fishing.
Knowing the exact geographic coordinates, you will need a map with latitude and longitude. It is enough to enter your data into the search form from the Yandex service to determine the location by coordinates successfully. Example, enter the latitude and longitude of Moskovskaya street 66 in the city of Saratov - 51.5339,46.0368. The service will quickly determine and display the location of a given house in the city as a mark.
In addition to the above, you can easily determine the coordinates on the map of any metro station in the city. After the name of the city we write the name of the station. And we observe where the mark is located and its coordinates with latitude and longitude. To determine the length of the route, you need to use the “Ruler” tool (measuring distances on the map). We put a mark at the beginning of the route and then at the end point. The service will automatically determine the distance in meters and show the track itself on the map.
It is possible to more accurately examine a place on the map thanks to the “Satellite” diagram (upper corner on the right). Look what it looks like. You can do all of the above operations with it.
World map with longitude and latitude
Imagine you are in an unfamiliar area, and there are no objects or landmarks nearby. And there is no one to ask! How could you explain your exact location so that you can be found quickly?
Thanks to concepts such as latitude and longitude, you can be detected and found. Latitude shows the location of an object in relation to the South and North Poles. The equator is considered to be zero latitude. The South Pole is located at 90 degrees. south latitude, and North at 90 degrees north latitude.
This data turns out to be insufficient. It is also necessary to know the situation in relation to the East and West. This is where the longitude coordinate comes in handy.
Thank you to the Yandex service for the data provided. Cards
Cartographic data of cities in Russia, Ukraine and the world
Geographical coordinates determine the position of a point on the earth’s surface or, more broadly, in the geographic envelope. Geographic coordinates are constructed according to the spherical principle. Similar coordinates are used on other planets, as well as on the celestial sphere.
Latitude
Main article: LatitudeLatitude- angle φ between the local zenith direction and the equatorial plane, measured from 0° to 90° on both sides of the equator. The geographic latitude of points located in the northern hemisphere (northern latitude) is usually considered positive, the latitude of points in the southern hemisphere is considered negative. It is customary to speak of latitudes close to the poles as high, and about those close to the equator - as about low.
Due to the difference in the shape of the Earth from a sphere, the geographic latitude of points differs somewhat from their geocentric latitude, that is, from the angle between the direction to a given point from the center of the Earth and the plane of the equator.
The latitude of a place can be determined using astronomical instruments such as a sextant or gnomon (direct measurement), or you can use GPS or GLONASS systems (indirect measurement).
Longitude
Main article: LongitudeLongitude- dihedral angle λ between the plane of the meridian passing through a given point and the plane of the initial prime meridian, from which longitude is measured. Longitude from 0° to 180° east of the prime meridian is called eastern, and to the west is called western. Eastern longitudes are considered to be positive, western longitudes are considered negative.
The choice of the prime meridian is arbitrary and depends only on agreement. Now the Greenwich meridian, passing through the observatory in Greenwich, in south-east London, is taken as the prime meridian. The meridians of the observatories of Paris, Cadiz, Pulkovo, etc. were previously chosen as the zero meridians.
Local solar time depends on longitude.
Height
Main article: Height above sea levelTo completely determine the position of a point in three-dimensional space, a third coordinate is needed - height. The distance to the center of the planet is not used in geography: it is convenient only when describing very deep regions of the planet or, on the contrary, when calculating orbits in space.
Within the geographical envelope it is usually used height above sea level, measured from the level of the “smoothed” surface - the geoid. Such a three-coordinate system turns out to be orthogonal, which simplifies a number of calculations. Altitude above sea level is also convenient because it is related to atmospheric pressure.
Distance from the earth's surface (up or down) is often used to describe a place, but "not" serves as a coordinate.
Geographic coordinate system
Rice. 1 In navigation, the center of mass of the vehicle (V) is selected as the origin of the coordinate system. The transition of the origin of coordinates from the inertial coordinate system to the geographic one (that is, from O i (\displaystyle O_(i)) to O g (\displaystyle O_(g))) is carried out based on the values of latitude and longitude. The coordinates of the center of the geographic coordinate system O g (\displaystyle O_(g)) in the inertial system take on the following values (when calculated using a spherical model of the Earth):
X o g = (R + h) cos (φ) cos (U t + λ) (\displaystyle X_(og)=(R+h)\cos(\varphi)\cos(Ut+\lambda)) Y o g = (R + h) cos (φ) sin (U t + λ) (\displaystyle Y_(og)=(R+h)\cos(\varphi)\sin(Ut+\lambda)) Z o g = ( R + h) sin (φ) (\displaystyle Z_(og)=(R+h)\sin(\varphi)) where R is the radius of the earth, U is the angular velocity of the earth's rotation, h is the height above sea level, φ (\displaystyle \varphi ) - latitude, λ (\displaystyle \lambda ) - longitude, t - time.
The orientation of the axes in the geographic coordinate system (G.S.K.) is selected according to the following scheme:
The X axis (another designation is the E axis) is the axis directed to the east. The Y axis (another designation is the N axis) is the axis directed to the north. The Z axis (another designation is the Up axis) is an axis directed vertically upward.
The orientation of the trihedron is XYZ, due to the rotation of the earth and the movement of the T.S. it is constantly shifting with angular velocities.
ω E = − V N / R (\displaystyle \omega _(E)=-V_(N)/R) ω N = V E / R + U cos (φ) (\displaystyle \omega _(N)=V_( E)/R+U\cos(\varphi)) ω U p = V E R t g (φ) + U sin (φ) (\displaystyle \omega _(Up)=(\frac (V_(E))(R ))tg(\varphi)+U\sin(\varphi)) where R is the radius of the earth, U is the angular velocity of the earth's rotation, V N (\displaystyle V_(N)) is the speed of the vehicle to the north, V E (\displaystyle V_ (E)) - to the east, φ (\displaystyle \varphi) - latitude, λ (\displaystyle \lambda) - longitude.
The main disadvantage in the practical application of G.S.K. in navigation is the large angular velocity of this system at high latitudes, increasing to infinity at the pole. Therefore, instead of G.S.K., semi-free in azimuth SK is used.
Semi-free in azimuth coordinate system
Semi-free in azimuth S.K. differs from G.S.K. only by one equation, which has the form:
ω U p = U sin (φ) (\displaystyle \omega _(Up)=U\sin(\varphi))
Accordingly, the system also has an initial position, carried out according to the formula
N = Y w cos (ε) + X w sin (ε) (\displaystyle N=Y_(w)\cos(\varepsilon)+X_(w)\sin(\varepsilon)) E = − Y w sin (ε) + X w cos (ε) (\displaystyle E=-Y_(w)\sin(\varepsilon)+X_(w)\cos(\varepsilon))
In reality, all calculations are carried out in this system, and then, to produce output information, the coordinates are converted into the GSK.
Geographic coordinate recording formats
Any ellipsoid (or geoid) can be used to record geographic coordinates, but WGS 84 and Krasovsky (in the Russian Federation) are most often used.
Coordinates (latitude from −90° to +90°, longitude from −180° to +180°) can be written:
- in ° degrees as a decimal (modern version)
- in ° degrees and ′ minutes with decimal fraction
- in ° degrees, ′ minutes and ″ seconds with decimal fraction (historical form of notation)
The decimal separator can be a period or a comma. Positive coordinate signs are represented by a (in most cases omitted) "+" sign or the letters: "N" - north latitude and "E" - east longitude. Negative coordinate signs are represented either by the sign “−” or by the letters: “S” is south latitude and “W” is west longitude. Letters can be placed either in front or behind.
There are no uniform rules for recording coordinates.
Search engine maps by default show coordinates in degrees with a decimal, with a “−” sign for negative longitude. On Google maps and Yandex maps, latitude comes first, then longitude (until October 2012, the reverse order was adopted on Yandex maps: first longitude, then latitude). These coordinates are visible, for example, when plotting routes from arbitrary points. Other formats are also recognized when searching.
At the same time, the original method of recording with degrees, minutes and seconds is often used. Currently, coordinates can be written in one of many ways or duplicated in two main ways (with degrees and with degrees, minutes and seconds). As an example, options for recording the coordinates of the sign “Zero kilometer of highways of the Russian Federation” are 55°45′21″ N. w. 37°37′04″ E. d.HGYAO:
- 55.755831°, 37.617673° - degrees
- N55.755831°, E37.617673° - degrees (+ additional letters)
- 55°45.35′N, 37°37.06′E - degrees and minutes (+ additional letters)
- 55°45′20.9916″N, 37°37′3.6228″E - degrees, minutes and seconds (+ additional letters)
GEOGRAPHIC MAP. DETERMINING LATITUDE AND LONGitude
Globe - model of the globe. It accurately conveys the outlines of continents and oceans and the ratio of their areas, which makes it possible to accurately measure the distances between individual places located on different continents and to find the shortest distances between them.
Along with its advantages, the globe has a significant drawback: it is produced only on a small scale. Imagine a globe on the scale of a wall map of Russia, then its diameter would be 2.55 m. Using such a globe would be inconvenient, since it would take up too much space.
A degree network is drawn on the globe, consisting of meridians and parallels, of which there are countless numbers that can be drawn. Usually on the globe and maps they are marked at 5, 10, 15°. The prime meridian is chosen arbitrarily and passes through Greenwich (a suburb of London). The equator is 40,075.7 km long and divides the Earth into the northern and southern hemispheres. Parallels are drawn parallel to the equator.
Using the degree network, the exact position of each point on Earth is determined, i.e. determine its geographic longitude and geographic latitude.
Geographic longitude is the angular distance of a given meridian from the initial one, with the vertex of the angle located at the center of the Earth. For ease of reference, longitude is measured east and west of the Greenwich meridian up to 180°. Longitude is called eastern when measured to the east (abbreviated as E) and western when measured to the west (abbreviated as W). Longitude is measured in degrees, minutes and seconds, for example: longitude of St. Petersburg 30° E; Longitude of Vladivostok 132° E. Longitude of New York 73° W; Longitude of Moscow 37°5"E (37 degrees 5 minutes East longitude).
Geographic latitude is the angular distance from the equator to a given parallel. The vertex of the angle is also located in the center of the Earth, but the angle does not lie in the plane of the equator, but in the plane of the meridian on which the desired point is located. Latitude is also measured in degrees, minutes and seconds from the equator to the north and south (from 0 to 90°). Latitude can be northern and southern (abbreviated as N, S), for example: Moscow latitude - 57° N, St. Petersburg latitude - 60° N, Melbourne latitude (Australia) - 38° S
The latitude and longitude of any point on the globe are its geographic coordinates.
Since the length of all meridians, unlike parallels, is the same, an arc of 1° of any meridian is approximately 111 km. It is somewhat smaller at the equator (110.57 km) and larger at the poles (111.7 km) due to the compression of the Earth at the poles.
What are latitude and longitude?
This is all wonderful, but latitude and longitude are NOT lines. These are angles, that's why they are measured in degrees! - 4 years agoLongitude and latitude are concepts used in indicating geographic coordinates.
For example, they say: the ship is located at 35 degrees north latitude and 28 degrees east longitude.
How can we understand this?
To understand, take a globe and touch your finger anywhere on the equator. Then spin the globe without removing your finger. By turning the globe, you change the position of your finger in longitude.
In the city of Greenwich there is a point where the longitude is zero degrees. This is the point through which the prime meridian passes.
Everything to the right on the map is called eastern longitude, and everything to the left is called western longitude. You can also simply say longitude, then the shift to the west or east will be determined by the sign of the angle. If the angle is negative, then the offset is to the west, and if it is positive, then it is to the east. What is an angle? The angle is the angle between point A with X coordinates at the Greenwich level and Y coordinates at the equator level, point O located in the center of the planet and point B with X coordinates of the desired point and Y coordinates at the equator level.
Latitude is approximately the same thing, only it is plotted vertically, that is, perpendicular to longitude. What is above the equator is northern latitude, and what is below is southern latitude. Or simply latitude, then downwards there is a decrease in the angle (negative angles), and upwards there is an increase.
Here's the diagram:
Mrs. Monica
Latitude and longitude are geographic coordinates, conventional lines on the surface of the globe.
Latitude is a conventional horizontal line (parallel), and longitude is a vertical line. The latitude reference point starts from the equator. This is zero latitude. Latitudes going from the equator to the North Pole are called Northern (N or N) from 0 to 90, from the equator to the South Pole - South (S or S).
The Greenwich meridian is considered the starting point of longitude. This is zero longitude. The longitude going from Greenwich to the east (towards Japan) is called Eastern longitude (E or E), from Greenwich to the west (towards America) is called Western longitude (W or W)
Each latitude and longitude is measured in degrees, each degree is divided into minutes, each minute into seconds. 1 degree = 60 minutes, 1 minute = 60 seconds. These are geometric and astronomical units of measurement.
Each degree, each minute and each second is equal to a certain distance, which changes as you approach the poles: the distance of each degree of latitude increases, and the distance of each degree of longitude decreases. All points of geographic coordinates converge at the poles, so there is only latitude (no longitude): the North Pole is 90°00?00?N latitude, the South Pole is 90°00?00?S latitude.
By definition, both latitude and longitude are angular coordinates that can be used to specify the location of any point on the globe. If on a plane the familiar X and Y are used, defined by metric units of measurement relative to perpendicular axes, then on a spherical surface angular coordinates are used, which show the position of a point relative to two also perpendicular lines on the surface and are measured in degrees. In the case of the Earth, these lines are the equator and the prime meridian. Latitude, north or south, is measured from the equator, and longitude, east or west, is measured from the prime meridian. The angle of latitude is determined by drawing conventional lines from the center of the earth to the desired point and the equator in the meridian plane, and the angle of longitude is determined by drawing the same lines from the center of the cross-section of the globe parallel between the desired point and the prime meridian.
Advice: in order not to be confused about what latitude and longitude are, it is better to remember, for example, the concept of northern and southern latitudes - it already becomes clear that latitude is a line above or below the equator, parallel to it, a parallel. And therefore longitude is a line perpendicular to the equator - a meridian.
Help to
Latitude and longitude are angles. Together they form coordinates that can be used to find the position of an object on a spherical surface like the Earth.
Latitude is defined in relation to the equator. That is, the equator is a zero surface. Positive latitude is northern latitude up to +90 degrees, and negative latitude is southern latitude up to -90 degrees.
Longitude is defined in terms of meridians. There is a main meridian from which the longitude count begins - this is Greenwich. All meridians that are to the east are negative longitude up to -180 degrees, and those to the west are positive longitude up to + 180 degrees.

Of course, everything will depend on the meaning of the word. After all, it can be the breadth of the soul and the length of the clothes. But, we still take geographical concepts as a basis. In order not to delve into specific and abstruse terminology, I will try to explain these concepts as simply as possible. After all, it is an accessible explanation that helps to remember information for a long time. I remember back in school they told us to imagine ourselves as travelers on a ship. And to understand where our ship is, we must learn to calculate latitude and longitude. To understand our location in relation to the North and South Pole, we need latitude.

Latitude and longitude are coordinates with which you can determine the location of an object on the surface of our planet or any other celestial body. Longitude can be east or west. Latitude can be determined using devices such as: a gnomon is an ancient astronomical instrument and a sextant-measuring, navigational instrument.
Modern satellite navigation systems such as GPS and GLONASS are used to determine latitude and longitude. Latitude and longitude are measured:

From school geography we know that geographic coordinates are used to determine the position of points on the Earth on an ellipsoid (sphere). The initial planes in the geographic coordinate system are the planes of the prime meridian and the equator, and the coordinates are angular values: longitude and latitude of the point. Determining the position of a point using latitudes and longitudes was introduced by Hipparchus in the 2nd century. BC e. Geographic latitude points are called corner between the equatorial plane and the normal (plumb line) drawn from a given point. Geographic longitude dots are dihedral angle between the plane of the prime (prime Greenwich) meridian and the plane of the meridian passing through a given point.
Azamatik
Good day.
Everyone has probably encountered and heard about such concepts as longitude and latitude.
Most often this happened in geography lessons.
So, both of these concepts mean an angle. Latitude- this is the angle between the equator, or rather its plane, and the line from this point; longitude this is the angle between the plane of the meridian passing through a given point and the plane of the prime meridian.
Longitudes from 0 to 180° east of that same prime meridian are usually called eastern (they are usually called or considered positive), and to the west - western (they are also called negative).
Longitude is the dihedral angle between the prime (Greenwich) meridian and the local meridian. Longitudes are counted from 0 to 180, from the Greenwich meridian. In general, longitude and latitude are the data necessary to determine a point in space, in a plane; from geodetic latitude and longitude, a transition is made to flat coordinates in the Gauss-Mercator projection for drawing up topographic plans of sites. Longitude and latitude can be geodetic, astronomical, depending on what coordinate system are you considering?
Moreljuba
Latitude and longitude are purely geographical indicators that are familiar to all schoolchildren. They use latitude and longitude to compile the coordinates of the location of an object.
And now in more detail on each concept separately:
1) This is what is meant by latitude:
2) This is what is meant by longitude:
To determine a point on the earth's surface, longitude and latitude are used. Latitude is the distance from a certain point to the equator, and longitude is the distance to the zero point of the meridian, or Greenwich. This distance is indicated in degrees, minutes and seconds.

LatitudeL9; - the angle between the local zenith direction and the equatorial plane, measured from 0 to 90° on both sides of the equator. The geographic latitude of points lying in the northern hemisphere (northern latitude) is usually considered positive, the latitude of points in the southern hemisphere - negative. In addition, it is customary to speak of latitudes that are larger in absolute value as high, and those close to zero (that is, to the equator) as low.
Due to the difference in the shape of the Earth (geoid) from a sphere, the geographic latitude of points differs somewhat from their geocentric latitude, that is, from the angle between the direction to a given point from the center of the Earth and the equatorial plane.
The latitude of a place can be determined using astronomical instruments such as a sextant or gnomon (direct measurement), you can also use GPS or GLONASS systems (indirect measurement). The length of the day depends on latitude, as well as on the time of year.
LongitudeL9; - the angle between the plane of the meridian passing through a given point and the plane of the initial prime meridian, from which longitude is calculated. Now on Earth the prime meridian is taken to be the one that passes through the old observatory in Greenwich, southeast London, and therefore it is called the Greenwich meridian. Longitudes from 0 to 180° east of the prime meridian are called eastern, and to the west - western. Eastern longitudes are considered to be positive, western longitudes are considered negative. It should be emphasized that, unlike latitude, for a system of longitudes the choice of the origin (prime meridian) is arbitrary and depends only on agreement. So, in addition to Greenwich, the meridians of the observatories of Paris, Cadiz, Pulkovo (on the territory of the Russian Empire), etc. were previously chosen as the zero meridians.
Local time depends on longitude.

In the Google Earth program, there is a GRID function, that is, a grid is drawn over the entire globe, you can test yourself and learn to understand. All parallels and meridians are signed. True in English, for example - 50 N and 50 E, that is, 50 degrees north latitude and 50 degrees east longitude. in general, to make it easier to remember, cut the Earth in half from north to south, and then along the equator.
Yulia Ostanina
Well, that means the object being defined has an address - this is latitude and longitude (for example, 57 N 33 E - these are the coordinates of the city of Moscow)
Latitude is horizontal lines, longitude is vertical.
Latitude can be north or south (north latitude or south latitude) depending on which side of the equator the object that needs to be determined is located on.
western and eastern longitude (w. and east) divides them by the prime meridian

You will need - a watch; - protractor
Instructions
1First you must determine geographic longitude. This value shows the deviation of the object from the prime meridian, from 0° to 180°. If the desired point is east of Greenwich, the value is called east longitude; if it is to the west, it is called west longitude. One degree is equal to 1/360 of the equator.

1First you must determine geographic longitude. This value shows the deviation of the object from the prime meridian, from 0° to 180°. If the desired point is east of Greenwich, the value is called east longitude; if it is to the west, it is called west longitude. One degree is equal to 1/360 of the equator.
2Pay attention to the fact that in one hour the Earth rotates by 15° of longitude, and in four minutes it moves by 1°. Your watch should show accurate local time. To find your geographic longitude, you need to set the local noon time.
3Find a straight stick 1-1.5 meters long. Stick it vertically into the ground. As soon as the shadow from the stick falls from south to north, and the sundial “shows” 12 o’clock, note the time. This is local noon. Convert the received data to Greenwich Time.
4Subtract 12 from the result obtained. Convert this difference to a degree measure. This method does not give 100% results, and the longitude from your calculations may differ from the true geographic longitude of your location by 0°-4°.
5Remember, if local noon occurs earlier than noon GMT, this is eastern longitude, if later, it is western longitude. Now you must set the geographic latitude. This value shows the deviation of an object from the equator to the north (north latitude) or south (south latitude) side, from 0° to 90°.
6. Note that the average length of one degree of latitude is approximately 111.12 km. To determine the geographic latitude, you need to wait until nightfall. Prepare a protractor and point its lower part (base) at the polar star.
7 Place the protractor upside down, but so that the zero degree is opposite the polar star. Look at what degree the hole in the middle of the protractor is opposite. This will be the geographic latitude.

1. To determine geographic latitude, the map shows parallels - lines drawn parallel to the equator. Geographic latitude is northern and southern. All points located in the northern hemisphere have northern latitude (N), and those in the southern hemisphere have southern latitude (S).
Geographic latitude shows the distance from the equator to a given point, expressed in degrees.
The geographic latitude of the equator is 0°. From the equator at an equal distance, in your maps, after 10 or 20 degrees, other parallels are drawn - use them to guide you. The further a point is from the equator, the greater its latitude.
At the poles the latitude is 90°.
2. To determine geographic longitude, the map shows meridians - lines that connect the north and south poles.
Everything to the right of the prime meridian is eastern longitude, everything to the left is western longitude.

These short designations come from the English language: West - west and East - east.
How to determine geographic coordinates from a map?
1. Find the geographic latitude of the point. To do this, you first need to determine in which hemisphere (northern or southern) it is located. If above the equator, then in the north, if below, then in the south.
Determine between which parallels the point is located (usually they are signed on the right or left of the edge of the map).
Find out how many degrees are from the nearest parallel from the equator to a given point.
2. Determine the geographic longitude of the point. To do this, first find out in which hemisphere (western or eastern) relative to Greenwich it is located. If to the left of Greenwich, then in the west, if to the right, then in the east.
Determine between which meridians the point is located (their longitude is usually written on the upper and lower edges of the map, and sometimes at the intersection with the equator).
Find out how many degrees it is to the point from the nearest meridian on the Greenwich side.
Globes and geographic maps have a coordinate system. With its help, you can plot any object on a globe or map, as well as find it on the earth's surface. What is this system, and how to determine the coordinates of any object on the surface of the Earth with its participation? We will try to talk about this in this article.
Geographic latitude and longitude
Longitude and latitude are geographical concepts that are measured in angular units (degrees). They serve to indicate the position of any point (object) on the earth's surface.
Geographic latitude is the angle between a plumb line at a particular point and the plane of the equator (zero parallel). Latitude in the Southern Hemisphere is called southern, and in the Northern Hemisphere it is called northern. Can vary from 0∗ to 90∗.
Geographic longitude is the angle made by the meridian plane at a certain point to the plane of the prime meridian. If the longitude is counted east from the prime Greenwich meridian, then it will be east longitude, and if it is to the west, then it will be west longitude. Longitude values can range from 0∗ to 180∗. Most often, on globes and maps, meridians (longitude) are indicated when they intersect with the equator.
How to determine your coordinates
When a person finds himself in an emergency situation, he must, first of all, be well oriented in the area. In some cases, it is necessary to have certain skills in determining the geographic coordinates of your location, for example, in order to convey them to rescuers. There are several ways to do this using improvised methods. We present the simplest of them.
Determining longitude by gnomon
If you go traveling, it is best to set your watch to Greenwich time:
- It is necessary to determine when it will be noon GMT in a given area.
- Stick a stick (gnomon) to determine the shortest solar shadow at noon.
- Find the minimum shadow cast by the gnomon. This time will be local noon. In addition, this shadow will point strictly north at this time.
- Using this time, calculate the longitude of the place where you are.
Calculations are made based on the following:
- since the Earth makes a complete revolution in 24 hours, therefore, it will travel 15 ∗ (degrees) in 1 hour;
- 4 minutes of time will be equal to 1 geographical degree;
- 1 second of longitude will be equal to 4 seconds of time;
- if noon occurs before 12 o'clock GMT, this means that you are in the Eastern Hemisphere;
- If you spot the shortest shadow after 12 o'clock GMT, then you are in the Western Hemisphere.
An example of the simplest calculation of longitude: the shortest shadow was cast by the gnomon at 11 hours 36 minutes, that is, noon came 24 minutes earlier than at Greenwich. Based on the fact that 4 minutes of time are equal to 1 ∗ longitude, we calculate - 24 minutes / 4 minutes = 6 ∗. This means that you are in the Eastern Hemisphere at 6 ∗ longitude.
How to determine geographic latitude
The determination is made using a protractor and a plumb line. To do this, a protractor is made from 2 rectangular strips and fastened in the form of a compass so that the angle between them can be changed.
- A thread with a load is fixed in the central part of the protractor and plays the role of a plumb line.
- With its base, the protractor is aimed at the North Star.
- 90 ∗ is subtracted from the angle between the plumb line of the protractor and its base. The result is the angle between the horizon and the North Star. Since this star is only 1 ∗ deviated from the axis of the world pole, the resulting angle will be equal to the latitude of the place where you are currently located.
How to determine geographic coordinates
The simplest way to determine geographic coordinates, which does not require any calculations, is this:
- Google maps opens.
- Find the exact place there;
- the map is moved with the mouse, moved away and zoomed in using its wheel
- find a settlement by name using the search.
- Right-click on the desired location. Select the required item from the menu that opens. In this case, “What is here?” Geographic coordinates will appear in the search line at the top of the window. For example: Sochi - 43.596306, 39.7229. They indicate the geographic latitude and longitude of the center of that city. This way you can determine the coordinates of your street or house.
Using the same coordinates you can see the place on the map. You just can’t swap these numbers. If you put longitude first and latitude second, you risk ending up in a different place. For example, instead of Moscow you will end up in Turkmenistan.
How to determine coordinates on a map
To determine the geographic latitude of an object, you need to find the closest parallel to it from the equator. For example, Moscow is located between the 50th and 60th parallels. The closest parallel from the equator is the 50th. To this figure is added the number of degrees of the meridian arc, which is from the 50th parallel to the desired object. This number is 6. Therefore, 50 + 6 = 56. Moscow lies on the 56th parallel.
To determine the geographic longitude of an object, find the meridian where it is located. For example, St. Petersburg lies east of Greenwich. Meridian, this one is 30 ∗ away from the prime meridian. This means that the city of St. Petersburg is located in the Eastern Hemisphere at a longitude of 30 ∗.
How to determine the coordinates of the geographic longitude of the desired object if it is located between two meridians? At the very beginning, the longitude of the meridian that is located closer to Greenwich is determined. Then to this value you need to add the number of degrees that is on the parallel arc the distance between the object and the meridian closest to Greenwich.
Example, Moscow is located east of the 30 ∗ meridian. Between it and Moscow the arc of parallel is 8 ∗. This means that Moscow has an eastern longitude and it is equal to 38 ∗ (E).
How to determine your coordinates on topographic maps? Geodetic and astronomical coordinates of the same objects differ on average by 70 m. Parallels and meridians on topographic maps are the inner frames of the sheets. Their latitude and longitude are written in the corner of each sheet. Western Hemisphere map sheets are marked "West of Greenwich" in the northwest corner of the frame. Maps of the Eastern Hemisphere will accordingly be marked “East of Greenwich.”
Mapping services on the Internet are becoming increasingly popular among network users and various mobile applications. Such resources are created in order to quickly find a city, country, street, and determine the coordinates of a populated area. In this regard, global search engines, for example, Yandex and Google, are releasing online and offline applications that allow you to search by coordinates on the map. By entering latitude and longitude data into the required line, a person is able to accurately determine where the desired object is located.
How to find out and enter the coordinates of a place
The user must download a map of the desired country or region to a computer, laptop or gadget. Searching for coordinates and entering them to determine the location is carried out as follows:
- Open the search bar on the map.
- Select an option from the proposed categories - “food”, “hotels”, “transport”, “attractions”, “shop”, “ATM”, “parking”, etc.
- Select the desired query option to determine the coordinates. First, the address. Here you enter the city, street, house number. Secondly, the name of the place. Thirdly, any keyword. The search bar will suggest possible words.
- Select “coordinates” in the search bar and click “show on map”. The desired object will be reflected on the map.
- In decimal degrees – 21.40043, 2.1235.
- In degrees and decimal minutes – 41 24.2028.
- In degrees, minutes and seconds – 28°29’12.2″N 5°12’20.5″E.
- The Latin letter d is replaced by a degree symbol.
- Use dots rather than commas to separate coordinates.
- First enter the latitude and then the longitude.
- Latitude is indicated in values from -90 degrees to 90 degrees.
- Longitude is indicated in the range from -180 degrees to 180 degrees.
It often happens that you need to find the location of a particular object in another country. In this case, the user first selects the country, and then searches for the location.
Determining the coordinates of an object is very simple. Having found a place on the map, the user clicks on it and looks at the bottom of the screen. The exact coordinates of the location will be indicated there. The information received is expressed in several formats:
You need to enter the existing coordinates into online maps correctly:
Introduction to geographic coordinates
Taking into account the fact that we have a bot that helps to find the coordinates of any geographical object Geographic coordinates of any cities in the world, the inverse problem naturally arises, and what object is located at the given coordinates. Moreover, the analysis of search queries suggests that such a task is not unique.
Therefore, we will try to help in solving the problem of searching for a geographical object at given coordinates.
We'll tell you the answers to frequently asked questions right away.
Point with coordinates 0 degrees latitude, 0 degrees longitude located on the equator, in the Gulf of Guinea off the western coast of Africa.
Coordinates zero (however, this can be any number) degrees longitude, 90 degrees south latitude- this is the South Pole, and 90 degrees north latitude, at any longitude- this is the North Pole.
Syntax
For those who use the XMPP client: rgeo<широта> <долгота>
Working through the site:<широта> <долгота>
Latitude - geographic latitude (can take values from -90 to +90), Longitude - geographic longitude (can take values from -180 to +180)
Geographic coordinates can be specified in the form of a degree and its fraction, as well as in the form of degrees, minutes and seconds, separated by : (colon)
For ease of perception and data entry, you will receive a response from the bot based on four values. The bot takes into account all points located in the southern/northern/eastern/western hemispheres.
That is, there is no need to enter a plus or minus before the latitude or longitude value.
Simply enter absolute coordinate values.
You will receive the result in the form of information about a populated area or geographic location located at these coordinates.
If nothing is found at the given coordinates, the bot will report that “you may have fallen into the ocean.” In this case, please adjust the specified parameters.
And one last thing. Since the bot uses the Google Maps service, the given values of the found geographical objects will be displayed in English.
Examples:
