Determining latitude and longitude on a map?

Determining the geographical coordinates of any city in the world (find out latitude and longitude) by 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 the desired city or countries, use the navigation and zoom tools. By zooming in and out +/-, also moving the interactive map, easy to find any country, 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 geographical coordinates center of Ukraine town. 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 notifying about 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 your 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 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. South Pole 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

Video tutorial " Geographic latitude and geographic longitude. Geographic Coordinates" will help you get an idea of geographic latitude and geographic longitude. The teacher will tell you how to correctly determine geographic coordinates.

Geographic latitude- arc length in degrees from the equator to a 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 like this: Moscow 55°45" N; latitude of New York - 40°43" N; Sydney - 33°52" S

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

Geographic longitude- length of the equatorial arc in degrees from the prime meridian (0 degrees) to the meridian of a given point.

The prime meridian is considered to be the Greenwich meridian (0 degrees).

Rice. 2. Determination of longitudes ()

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

For example, the longitude of Moscow is 37 degrees and 37 minutes east longitude, it is written like this: 37°37" east; the longitude of Mexico City is 99°08" west.

Rice. 3. Geographical latitude and geographic longitude

To accurately determine the location of an object on the surface of the Earth, you need to know its geographic latitude and geographic longitude.

Geographical coordinates- quantities that determine the position of a point on the 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 First the latitude value is recorded.

Sometimes you need to find an object at already given coordinates; to do this, you must first guess in which hemispheres the object is located.

Good day!

Almost all of us have found ourselves in a situation where we are wandering in an unfamiliar part of the city and trying to find the right address. Now, of course, technology has stepped forward and an ordinary smartphone allows you to navigate the area perfectly...

However, not everywhere and not everything is depicted on Google and Yandex maps. Not long ago I was in a new part of my city, and, as it turned out, some streets in this area were simply not shown on the map. How can you tell another person where you are and how to find you?

Actually, this short note is dedicated to coordinates and searching for a specific point on the map using map services from Yandex and Google. So...

How to determine your coordinates and how to find an address using coordinates

I'll start with Google maps, official website :

To accurately determine your coordinates, click on the “Location Determination” button; usually a small window immediately pops up in the browser asking whether to allow access (select “I allow”).

Important! By the way, in some cases different services may show you in “different places”. Therefore, double-check your coordinates using 2 maps at once.

If the street is long and there are no house numbers (or Google maps do not indicate houses in this area at all) - then left-click on the point next to the one identified by Google - a small tab should pop up at the bottom, in which your coordinates!

Coordinates represent consists of two numbers. For example, in the screenshot below these are: 54.989192 and 73.319559

Knowing these numbers, you can transmit your location to anyone (even if he does not use Google maps, which is very convenient).

To find the desired point in Google by coordinates, simply open maps and enter these two numbers in the search bar (top left): after 1-2 seconds. A red flag will light up on the maps indicating the desired point.

Note:

coordinates must be indicated using a dot, not a comma (correct: 54.989192 73.319559; incorrect: 54.989192 and 73.319559);
indicate the coordinates in the order in which the map gives them to you: i.e. first latitude, then longitude (if you break the order, you will get a completely wrong point, perhaps even 1000 km further than the one you are looking for...);
coordinates can be specified in degrees and minutes (example: 51°54" 73°31").

Yandex maps

BY by and large, with Yandex maps the principle of operation is similar. It is worth noting that if the address is not determined for one service, try using another. Sometimes, if a street or area is not drawn in Google maps, then in Yandex, on the contrary, it is displayed quite fully, all the streets are signed, and you can easily find your way where to go and what to do.

Yandex Maps also has a special one. a tool that allows you to find out your location online (click on the arrow in the white circle on the right, see screenshot below).

To determine the coordinates - just click on the desired point on the map - a small window will pop up with addresses and two numbers - this is what they are.

You can insert both a specific address and coordinates into the search line (don’t forget that they need to be specified correctly: do not confuse the sequence, specify through a dot, not a comma!).

Addition!

I have another article of a similar nature on my blog - about determining distances between cities, choosing the optimal road and estimating travel time. It will be useful to anyone who is planning to travel to another city, I recommend:

Additions are welcome...

Counted 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.

Longitude

Longitude- 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. 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.

Height

To 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 geographic envelope, the “height above sea level” is usually used, measured from the level of the “smoothed” surface - the geoid. Such system of three coordinates 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, however Not serves coordinate

Geographic coordinate system

The main disadvantage in practical application GSK in navigation is the large angular velocity of this system at high latitudes, increasing to infinity at the pole. Therefore, instead of the GSK, a semi-free CS in azimuth is used.

Semi-free in azimuth coordinate system

The azimuth-semi-free CS differs from the GSK in only one equation, which has the form:

Accordingly, the system also has starting position that the GCS and their orientation also coincide with the only difference that its axes and are deviated from the corresponding axes of the GCS by an angle for which the equation is valid

The conversion between the GSK and the semi-free CS in azimuth is carried out according to the formula

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

The WGS84 system is used to record geographic coordinates.

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 s decimal
in ° degrees, "minutes and" seconds with decimal fraction (historical form of notation)

The decimal separator is always a dot. Positive coordinate signs are represented by a (in most cases omitted) "+" sign, or by the letters: "N" - north latitude and "E" - east longitude. Negative coordinate signs are represented either by a “-” 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.

On the maps search engines By default, coordinates are shown in degrees with decimal fractions, with “-” signs 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.

In navigators, by default, degrees and minutes with a decimal fraction with a letter designation are often shown, for example, in Navitel, in iGO. You can enter coordinates in accordance with other formats. The degrees and minutes format is also recommended for maritime radio communications.

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” - 55.755831 , 37.617673 55°45′20.99″ n. w. / 55.755831 , 37.617673 37°37′03.62″ E. d.:

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)

What is a coordinate system?

People invented a system that reads the coordinates of any point a long time ago. This system consists of parallels indicating latitude and meridians indicating longitude.

Since it was difficult to determine latitude and longitude by eye, a grid of longitudinal and transverse arcs, indicated by numbers, began to be applied over all types of geographical images.

What does latitude mean?

The number responsible for the latitude of a place on the map indicates its distance relative to the equator - the further the point is from it and the closer to the pole, the more its digital value increases.

On flat images, as well as globes, latitude is determined by spherical lines drawn horizontally and parallel to the equator - parallels.
At the equator there is a zero parallel, towards the poles the value in numbers increases.
Parallel arcs are designated in degrees, minutes, seconds, as angular measurements.
From the equator towards the north pole, the value will have positive values from 0º to 90º, indicated by the symbols “n. latitude,” that is, “north latitude.”
And from the equator towards the south - negative, from 0º to -90º, indicated by the symbols “southern latitude”, that is, “southern latitude”.
The values 90º and -90º are at the peak of the poles.
Latitudes close to the equator are called “low”, and those close to the poles are called “high”.

To determine the location of the required object relative to the equator, you just need to correlate its point with the nearest parallel, and then look at what number is opposite it to the left and right behind the map field.

If the point is located between the lines, you must first determine the nearest parallel.
If it is north of the desired point, then the coordinate of the point will be smaller, so from the nearest horizontal arc you need to subtract the difference in degrees to the object.
If the nearest parallel is below the desired point, then the difference in degrees is added to its value, since the desired point will have a larger value.

Since it is sometimes difficult to determine latitude and longitude on a map at a glance, they use a ruler with a pencil or compass.

Remember! All points on the globe, and accordingly on a map or globe, located along one parallel arc will have the same value in degrees.

What does longitude mean?

Meridians are responsible for longitude - vertical spherical arcs converging at the poles into one point, dividing the globe into 2 hemispheres - western or eastern, which we are used to seeing on the map in the form of two circles.

Meridians similarly facilitate the task of accurately determining the latitude and longitude of any point on earth, since the place of their intersection with each of the parallels is easily indicated by a digital mark.
The value of vertical arcs is also measured in angular degrees, minutes, seconds, ranging from 0º to 180º.
Starting from 1884, it was decided to take the Greenwich meridian as the zero mark.
All coordinate values in the direction west of Greenwich are designated by the symbol “W,” that is, “western longitude.”
All values in the direction east of Greenwich are designated by the symbol “E,” that is, “Eastern longitude.”
All points located along the same meridian arc will have the same designation in degrees.

Remember! To calculate the longitude value, you need to correlate the location of the desired object with the digital designation of the nearest meridian, which is placed outside the image fields above and below.

How to find the coordinates of the desired point

The question often arises of how to determine latitude and longitude on a map if the desired point, distant from the coordinate grid, is located inside a square.

Calculating coordinates is also difficult when the terrain image has huge scale, but I don’t have more detailed information with me.

Here you cannot do without special calculations - you will need a ruler with a pencil or a compass.
First, the nearest parallel and meridian are determined.
Their digital designation is recorded, then the step.
Next, the distance from each arc is measured in millimeters, then converted to kilometers using a scale.
All this correlates with the pitch of parallels, as well as the pitch of meridians drawn on a certain scale.
There are images with different pitches - 15º, 10º, and there are less than 4º, this directly depends on the scale.
Having found out the distance between the nearest arcs, also the value in degrees, you need to calculate the difference, by how many degrees a given point is deviated from the coordinate grid.
Parallel - if the object is in the northern hemisphere, then we add the resulting difference to the smaller number, and subtract it from the larger one; for the southern hemisphere this rule works similarly, only we carry out the calculations as with positive numbers, but the final number will be negative.
Meridian - the position of a given point in the eastern or western hemisphere does not affect the calculations; we add our calculations to the smaller value of the parallel, and subtract from the larger value.

Using a compass is also easy to calculate the geographic location - to get the value of the parallel, its ends need to be placed on the point of the desired object and the nearest horizontal arc, and then the thrust of the compass must be transferred to the scale of the existing map. And to find out the size of the meridian, repeat all this with the nearest vertical arc.
