Geographical coordinates determine the position of a point on the earth's surface. Geographic coordinates are based on the spherical principle and consist of latitude and longitude.
Latitude- the angle between the local direction of the zenith and the plane of the equator, measured from 0 ° to 90 ° on both sides of the equator. The geographic 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, but about those close to the equator - how about low.
Longitude- the angle between the plane of the meridian passing through this point and the plane of the initial zero meridian, from which the longitude is measured. Longitudes from 0 ° to 180 ° east of the prime meridian are called eastern, to the west - western. Eastern longitudes are considered to be positive, while western longitudes are considered negative.
Geographic coordinates recording format
The geographic coordinates of one point can be expressed in different formats. Depending on whether minutes and seconds are represented as values from 0 to 60 or 0 to 100 (decimal places).
The coordinate format is usually written as follows: DD- degrees, MM- minutes, SS- seconds, if minutes and seconds are presented as decimal fractions, then they simply write DD.DDDD... For instance:
- DD MM SS: 50 ° 40 "45" "E, 40 50" 30 "" N - degrees, minutes, seconds
- DD MM.MM: 50 ° 40.75 "E, 40 50.5" N - degrees, decimal minutes
- DD.DDDDD: 50.67916 E, 40.841666 N - decimal degrees
Why do you need to know the coordinates of your home
Often, houses in summer cottages and many villages do not have a clear navigation consisting of signs with street names and house numbers, or even houses with signs with numbers can be scattered throughout the village in random order (historically, as the village is being built up). There are times when everything is fine with navigation in the settlement, but not all car GPS-navigators have such a house or street. Residents of such houses have to explain for a long time and, as a rule, confusingly how to get to them using different landmarks. In this case, it is easier to give the coordinates of the house, because any car navigator can pave the way along the coordinates.
To work out the technical possibility of connecting the Internet in a country house, we also ask our customers to provide the coordinates of the house, especially if it is not located at the address on any of the online cartographic services.
Determination of coordinates using online cartographic services
Currently, the most famous online cartographic services with a search function are Google and Yandex maps. Consider how you can determine the geographical coordinates on a map or satellite image in the service Google Maps:
2. Find the exact location on the map. For this, the map can be moved mouse, zoom in and out by scrolling the mouse wheel. You can also find the location you want using search by name using the locality, street and house. To find the place of your home as accurately as possible, switch between display modes: Map, Hybrid or Satellite.
3. Click right by clicking on the desired location on the map and choose from the menu that opens paragraph “What's in there?” . A marker in the form of a green arrow will appear on the map. Repeat the operation if the marker is not positioned accurately.
4. When you hover the mouse over the green arrow, the geographical coordinates of the place will appear, they will also appear in the search bar from where they can be copied to the clipboard.
Rice. 1. Determining the coordinates of a place by a pointer on a Google map
Now let's look at how you can determine the geographical coordinates on a map or satellite image in the service Yandex maps:
To find a place, we will use the same algorithm as for searching on Google maps. Open Yandex.Maps: http://maps.yandex.ru. To obtain coordinates on the Yandex map, use tool"Get information"(button with an arrow and a question mark, in the upper left part of the map). When you click on the map with this tool, a marker appears on it, and the coordinates are displayed in the search bar.
Rice. 2. Determination of the coordinates of the place by the pointer on the Yandex map
On search engine maps, by default, coordinates are shown in degrees with a decimal fraction with "-" signs for negative longitude. On Google maps and Yandex maps, first latitude, then longitude (until October 2012, the reverse order was adopted on Yandex maps: first longitude, then latitude).
Coordinates are called angular and linear quantities (numbers) that determine the position of a point on a surface or in space.
In topography, coordinate systems are used that allow the most simple and unambiguous determination of the position of points on the earth's surface both from the results of direct measurements on the ground and using maps. Such systems include geographic, planar rectangular, polar and bipolar coordinates.
Geographical coordinates(Fig. 1) - angular values: latitude (j) and longitude (L), which determine the position of an object on the earth's surface relative to the origin of coordinates - the point of intersection of the initial (Greenwich) meridian with the equator. On a map, a geographic grid is indicated by a scale on all sides of the map frame. The west and east sides of the frame are meridians, while the north and south are parallels. In the corners of the map sheet, the geographic coordinates of the points of intersection of the frame sides are signed.
Rice. 1. System of geographic coordinates on the earth's surface
In the geographic coordinate system, the position of any point on the earth's surface relative to the origin of coordinates is determined in angular measure. The point of intersection of the initial (Greenwich) meridian with the equator is taken as the beginning in our country and in most other states. Thus, being the same for the entire planet, the geographic coordinate system is convenient for solving problems of determining the relative position of objects located at significant distances from each other. Therefore, in military affairs, this system is used mainly for conducting calculations related to the use of long-range combat assets, for example, ballistic missiles, aviation, etc.
Plane rectangular coordinates(Fig. 2) - linear quantities that determine the position of the object on the plane relative to the accepted origin of coordinates - the intersection of two mutually perpendicular straight lines (coordinate axes X and Y).
In topography, each 6-degree zone has its own rectangular coordinate system. The X-axis is the axial meridian of the zone, the Y-axis is the equator, and the point of intersection of the axial meridian with the equator is the origin.
Rice. 2. System of plane rectangular coordinates on maps
The plane rectangular coordinate system is zonal; it is set for each six-degree zone into which the Earth's surface is divided when it is displayed on maps in the Gaussian projection, and is designed to indicate the position of the images of points on the earth's surface on the plane (map) in this projection.
The origin of coordinates in the zone is the point of intersection of the axial meridian with the equator, relative to which the position of all other points of the zone is determined in a linear measure. The origin of the zone coordinates and its coordinate axes occupy a strictly defined position on the earth's surface. Therefore, the system of planar rectangular coordinates of each zone is associated with both the coordinate systems of all other zones and the geographic coordinate system.
The use of linear values to determine the position of points makes the system of flat rectangular coordinates very convenient for making calculations both when working on the ground and on a map. Therefore, in the troops, this system is most widely used. Rectangular coordinates indicate the position of terrain points, their battle formations and targets, with their help they determine the relative position of objects within one coordinate zone or in adjacent areas of two zones.
Polar and bipolar coordinate systems are local systems. In military practice, they are used to determine the position of some points relative to others in relatively small areas of terrain, for example, when target designation, intersection of landmarks and targets, drawing up terrain diagrams, etc. These systems can be associated with systems of rectangular and geographic coordinates.
2. Determination of geographical coordinates and plotting objects on a map by known coordinates
The geographical coordinates of a point located on the map are determined from the closest parallel and meridian, the latitude and longitude of which are known.
The frame of the topographic map is divided into minutes, which are divided by dots into divisions of 10 seconds each. Latitudes are indicated on the sides of the frame, and longitudes are indicated on the north and south sides.
Rice. 3. Determination of the geographical coordinates of the point on the map (point A) and plotting the point on the map using geographical coordinates (point B)
Using the minute frame of the map, you can:
1 ... Determine the geographical coordinates of any point on the map.
For example, the coordinates of point A (Fig. 3). To do this, it is necessary to measure the shortest distance from point A to the southern frame of the map using a caliper-measuring device, then attach the caliper to the western frame and determine the number of minutes and seconds in the measured segment, add the resulting (measured) value of minutes and seconds (0 "27") with the latitude of the southwest corner of the frame - 54 ° 30 ".
Latitude points on the map will be equal to: 54 ° 30 "+0" 27 "= 54 ° 30" 27 ".
Longitude is defined similarly.
The shortest distance from point A to the western frame of the map is measured with a caliper-measuring compass, the caliper is applied to the southern frame, the number of minutes and seconds in the measured segment (2 "35") is determined, the obtained (measured) value is added with the longitude of the south-western corner frames - 45 ° 00 ".
Longitude points on the map will be equal to: 45 ° 00 "+2" 35 "= 45 ° 02" 35 "
2. Put any point on the map at the specified geographic coordinates.
For example, point B latitude: 54 ° 31 "08", longitude 45 ° 01 "41".
To map a point in longitude, you need to draw the true meridian through this point, for which you connect the same number of minutes along the northern and southern frames; to map a point in latitude, you need to draw a parallel through this point, for which you connect the same number of minutes along the western and eastern frames. The intersection of the two lines will determine the location of point B.
3. Rectangular grid on topographic maps and its digitization. Additional mesh at the junction of coordinate zones
The coordinate grid on the map is a grid of squares formed by lines parallel to the coordinate axes of the zone. Grid lines are drawn through an integer number of kilometers. Therefore, the coordinate grid is also called the kilometer grid, and its lines are called kilometers.
On map 1: 25000, the lines forming a coordinate grid are drawn every 4 cm, that is, every 1 km on the ground, and on maps 1: 50,000-1: 200000 every 2 cm (1.2 and 4 km on the ground, respectively). On the map 1: 500000, only the outputs of the grid lines are plotted on the inner frame of each sheet every 2 cm (10 km on the ground). If necessary, coordinate lines can be plotted on the map along these outputs.
On topographic maps, the values of abscissas and ordinates of coordinate lines (Fig. 2) are signed at the outputs of the lines outside the inner frame of the sheet and in nine places on each sheet of the map. The full values of abscissas and ordinates in kilometers are labeled near the coordinate lines closest to the corners of the map frame and near the intersection of coordinate lines closest to the northwest corner. The rest of the coordinate lines are signed with abbreviated two numbers (tens and units of kilometers). The labels near the horizontal lines of the coordinate grid correspond to the distances from the ordinate in kilometers.
The labels near the vertical lines indicate the zone number (one or two first digits) and the distance in kilometers (always three digits) from the origin, conventionally shifted to the west of the zone's axial meridian by 500 km. For example, the signature 6740 means: 6 - zone number, 740 - distance from the conventional origin in kilometers.
On the outer frame, the outputs of the coordinate lines are given ( additional mesh) coordinate systems of the adjacent zone.
4. Determination of rectangular coordinates of points. Plotting points by their coordinates
On a grid using a compass (ruler), you can:
1. Determine the rectangular coordinates of a point on the map.
For example, point B (Fig. 2).
For this you need:
- write down X - digitizing the lower kilometer line of the square in which point B is located, i.e. 6657 km;
- measure along the perpendicular the distance from the lower kilometer line of the square to point B and, using the linear scale of the map, determine the value of this segment in meters;
- add the measured value of 575 m with the digitization value of the lower kilometer line of the square: X = 6657000 + 575 = 6657575 m.
The ordinate Y is determined in the same way:
- write down the Y value - digitizing the left vertical line of the square, i.e. 7363;
- measure along the perpendicular the distance from this line to point B, i.e. 335 m;
- add the measured distance to the digitization value Y of the left vertical line of the square: Y = 7363000 + 335 = 7363335 m.
2. Put the target on the map at the specified coordinates.
For example, point G by coordinates: X = 6658725 Y = 7362360.
For this you need:
- find the square in which the point G is located by the value of whole kilometers, i.e. 5862;
- set aside from the lower left corner of the square a segment on the map scale equal to the difference between the abscissa of the target and the lower side of the square - 725 m;
- from the obtained point along the perpendicular to the right, postpone a segment equal to the difference between the ordinates of the target and the left side of the square, i.e. 360 m.

5. Accuracy of determining coordinates on maps of various scales
The accuracy of determining geographic coordinates on maps 1: 25000-1: 200000 is about 2 and 10 "", respectively.
The accuracy of determining the rectangular coordinates of points on the map is limited not only by its scale, but also by the amount of errors allowed when shooting or compiling a map and plotting various points and terrain objects on it
Most accurately (with an error not exceeding 0.2 mm), geodetic points and are plotted on the map. objects that stand out most sharply on the ground and are visible from a distance, which have a meaning of landmarks (individual bell towers, factory chimneys, tower-type buildings). Therefore, the coordinates of such points can be determined with approximately the same accuracy with which they are plotted on the map, i.e. for a 1: 25000 scale map - with an accuracy of 5-7 m, for a 1: 50,000 scale map - with an accuracy of 10 15 m, for a map with a scale of 1: 100000 - with an accuracy of 20-30 m.
The rest of the landmarks and points of the contours are plotted on the map, and, therefore, are determined from it with an error of up to 0.5 mm, and the points related to contours that are indistinct on the ground (for example, the contour of a swamp), with an error of up to 1 mm.
6. Determination of the position of objects (points) in systems of polar and bipolar coordinates, plotting objects on the map by direction and distance, by two angles or by two distances
System flat polar coordinates(Fig. 3, a) consists of the point O - the origin of coordinates, or poles, and the initial direction of the OP, called polar axis.
Rice. 3. a - polar coordinates; b - bipolar coordinates
The position of point M on the terrain or on the map in this system is determined by two coordinates: the position angle θ, which is measured clockwise from the polar axis to the direction to the determined point M (from 0 to 360 °), and the distance ОМ = D.
Depending on the problem being solved, an observation post, a firing position, a starting point of movement, etc., are taken as a pole, and a geographic (true) meridian, a magnetic meridian (direction of a compass magnetic needle) or a direction to a landmark ...
These coordinates can be either two position angles defining the directions from points A and B to the desired point M, or the distance D1 = AM and D2 = BM to it. The angles of position in this case, as shown in Fig. 1, b, are measured at points A and B or from the direction of the basis (i.e. angle A = BAM and angle B = ABM) or from any other directions passing through points A and B and taken as initial. For example, in the second case, the place of point M is determined by the angles of position θ1 and θ2, measured from the direction of the magnetic meridians. planar bipolar (bipolar) coordinates(Fig. 3, b) consists of two poles A and B and a common axis AB, called the base or the base of the intersection. The position of any point M relative to two data on the map (terrain) of points A and B is determined by coordinates that are measured on the map or on the ground.
Drawing the detected object on the map
This is one of the most important points in object detection. The accuracy of determining its coordinates depends on how accurately the object (target) will be mapped.
Having found an object (target), you must first accurately determine by various signs what is detected. Then, without stopping observing the object and without revealing yourself, put the object on the map. There are several ways to draw an object on the map.
Ocularly- Draws an object on the map if it is near a known landmark.
By direction and distance: to do this, you need to orient the map, find your point of position on it, trace the direction to the detected object on the map and draw a line to the object from your point of position, then determine the distance to the object by measuring this distance on the map and measuring it with the scale of the map.
Rice. 4. Drawing the target on the map with a straight line intersection from two points.
If in this way it is graphically impossible to solve the problem (the enemy interferes, poor visibility, etc.), then you need to accurately measure the azimuth to the object, then translate it into a directional angle and draw a direction on the map from the standing point, on which to postpone the distance to the object.
To get the directional angle, you need to add the magnetic declination of this map (direction correction) to the magnetic azimuth.
Serif... In this way, an object is put on a map from 2 to 3 points from which it is possible to observe it. To do this, from each selected point, a direction to the object is drawn on an oriented map, then the intersection of straight lines determines the location of the object.
7. Methods of target designation on the map: in graphic coordinates, flat rectangular coordinates (full and abbreviated), in squares of a kilometer grid (up to a whole square, up to 1/4, up to 1/9 of a square), from a landmark, from a conventional line, in azimuth and target range, in the bipolar coordinate system
The ability to quickly and correctly indicate targets, landmarks and other objects on the ground is essential for controlling units and fire in battle or for organizing combat.
Targeting in geographic coordinates it is used very rarely and only in cases where targets are removed from a given point on the map at a considerable distance, expressed in tens or hundreds of kilometers. In this case, geographic coordinates are determined from the map, as described in question number 2 of this lesson.
The location of the target (object) is indicated by latitude and longitude, for example, altitude 245.2 (40 ° 8 "40" N, 65 ° 31 "00" E). On the eastern (western), northern (southern) sides of the topographic frame, mark the position of the target in latitude and longitude with an injection of a compass. From these marks, perpendiculars are lowered into the depth of the topographic map sheet until they intersect (command rulers, standard sheets of paper are applied). The point of intersection of perpendiculars is the position of the target on the map.
For approximate target designation rectangular coordinates it is enough to indicate on the map the grid square where the object is located. The square is always indicated by the numbers of the kilometer lines, the intersection of which forms the southwest (lower left) corner. When specifying a square, the card adheres to the rule: first, they name two numbers signed at the horizontal line (at the western side), that is, the "X" coordinate, and then two numbers at the vertical line (the southern side of the sheet), that is, the "Y" coordinate. In this case, "X" and "Y" are not spoken. For example, enemy tanks have been spotted. When transmitting a report by radiotelephone, the square number is pronounced: "Eighty eight zero two".
If the position of a point (object) needs to be determined more precisely, then full or abbreviated coordinates are used.
Work with the full coordinates... For example, you need to determine the coordinates of the road indicator in square 8803 on a map with a scale of 1: 50000. First, determine what is the distance from the lower horizontal side of the square to the road sign (for example, 600 m on the ground). In the same way, measure the distance from the left vertical side of the square (for example, 500 m). Now, by digitizing kilometer lines, we determine the full coordinates of the object. The horizontal line has the signature 5988 (X), adding the distance from this line to the road sign, we get: X = 5988600. In the same way, we define the vertical line and get 2403500. The full coordinates of the road indicator are as follows: X = 5988600 m, Y = 2403500 m.
Abbreviated coordinates respectively will be equal: X = 88600 m, Y = 03500 m.
If it is required to clarify the position of the target in the square, then target designation is used in an alphabetic or digital way inside the square of the kilometer grid.
When targeting letter way inside the square of the kilometer grid, the square is conventionally divided into 4 parts, each part is assigned a capital letter of the Russian alphabet.
The second way is digital way target designation inside the square of the kilometer grid (target designation by snail ). This method got its name from the arrangement of conditional digital squares inside the square of the kilometer grid. They are arranged as if in a spiral, while the square is divided into 9 parts.
When targeting in these cases, they call the square in which the target is located, and add a letter or number that specifies the position of the target inside the square. For example, height 51.8 (5863-A) or high voltage support (5762-2) (see Fig. 2).
Target designation from a landmark is the simplest and most common method of target designation. With this method of target designation, the landmark closest to the target is first called, then the angle between the direction to the landmark and the direction to the target in divisions of the goniometer (measured with binoculars) and the distance to the target in meters. For instance: "The second landmark, forty to the right, then two hundred, at a separate bush - a machine gun."
Target designation from the conditional line usually used on the move in combat vehicles. With this method, two points are selected on the map in the direction of action and connected with a straight line, relative to which target designation will be carried out. This line is designated by letters, divided into centimeter divisions and numbered starting from zero. Such a construction is done on the maps of both the transmitting and receiving target designation.
Targeting from a conventional line is usually used in motion on combat vehicles. With this method, two points are selected on the map in the direction of action and connected with a straight line (Fig. 5), relative to which target designation will be carried out. This line is designated by letters, divided into centimeter divisions and numbered starting from zero.
Rice. 5. Targeting from a conventional line
Such a construction is done on the maps of both the transmitting and receiving target designation.
The position of the target relative to the conditional line is determined by two coordinates: a segment from the starting point to the base of the perpendicular dropped from the point of the target location to the conditional line, and a segment of the perpendicular from the conditional line to the target.
When targeting, the symbolic name of the line is called, then the number of centimeters and millimeters contained in the first segment, and, finally, the direction (left or right) and the length of the second segment. For instance: “Direct AC, five, seven; zero to the right, six - NP ".
Target designation from a conventional line can be issued by indicating the direction to the target at an angle from the conventional line and the distance to the target, for example: "Straight AC, to the right 3-40, twelve hundred - machine gun."
Target designation in azimuth and range to the target... The azimuth of the direction to the target is determined using a compass in degrees, and the distance to it is determined using an observation device or visually in meters. For instance: "Azimuth thirty-five, range six hundred - a tank in a trench." This method is most often used on terrain where there are few landmarks.
8. Problem solving
Determination of the coordinates of terrain points (objects) and target designation on the map are practiced practically on training maps using previously prepared points (plotted objects).
Each learner defines geographic and rectangular coordinates (maps objects to known coordinates).
Target designation methods on the map are being worked out: in flat rectangular coordinates (full and abbreviated), in squares of a kilometer grid (up to a whole square, up to 1/4, up to 1/9 of a square), from a reference point, in azimuth and target range.

Map data of cities in Russia, Ukraine and the world
Modern technologies make our life much easier, making it easier, simpler and more convenient. Among the variety of such innovations, an important place is occupied by tools that make it easy to navigate the terrain, build a convenient route to a particular geographical point, find place names and other topographic objects on the map. One of the options for finding the desired object on the map is to search for it using geographic coordinates. And in this article I will tell you how to search by coordinates on Yandex Map, and what are the features of this search.
As you know, in the modern digital market of cartographic services, there are several competing companies offering the user the ability to search for a point by coordinates. The list of such services includes the popular “Google Maps”, “Yandex.Maps”, “2GIS” (specialization in detailing cities), “Bing Maps”, “HERE WeGo”, “OpenStreetMap” the previously existed “Yahoo! Maps ”(now closed).
The main competitors in the Russian market are “ Google.Maps" and " Yandex maps". If the use of Google maps is preferred on a global scale, then in the vastness of Russia we would recommend using the Yandex service. The latter provides better coverage of Russia, has a high level of detail, boasts a special tool for editing maps by users called "People's Map", displays traffic jams in domestic cities, works well with "Geocoder", has other useful features.
To determine the location on the territory of the Russian Federation, it is better to use "Yandex.Maps" In this case, you can use the Yandex.Maps functionality both with the help of a regular stationary browser on a PC, and by installing the mobile application of the same name on your phone (for example, from the Play Market).
Search by latitude and longitude
If you are faced with the question of finding a geographic place on the map, or there is a need to point to a place on the map for another person, then you should use the method of determining the location of a geographic object by its coordinates, including latitude or longitude.
Let me remind the reader that latitude coordinates show the location of the desired object in relation to the North and South Pole (i.e. it is a point between north and south), and longitude coordinates determine the location of the object between east and west.
Zero latitude is usually considered the equator, therefore, the south pole is at 90 degrees south latitude, and the north pole is at 90 degrees north latitude.
In this case, the north latitude is denoted by the letter "N" (Nord - north), South - by the letter "S" (South - south), west longitude by the letter "W" (West - west), and east longitude by the letter "E" (East - east ).
Find a place by coordinates on Yandex Map
To determine the latitude and longitude coordinates of an object, it is enough to open Yandex.Maps, find the object we need on the map, and click on it with the cursor. A small window will immediately open next to the cursor, informing about the selected object, and indicating its coordinates in latitude and longitude.
Now, to find this object on the map, it will be enough to write down these numerical values, and then simply enter them separated by commas in the Yandex.Maps search bar and press enter. The map will immediately move to this place, and will point you to the object specified by the entered coordinates.
It is most convenient to share such coordinates while being somewhere in nature, the other side will easily find your location by simply typing your coordinates into the Yandex.Maps search box.
In addition to finding the desired point in latitude and longitude, the Yandex.Maps functionality makes it possible to build a pedestrian, car, bus route to it. To do this, just enter the latitude and longitude numbers of the object you need into the search line, press enter, and after it is displayed on the screen, click on the button on the left "Build a route".
Click on "Build a route" to build different route options to the desired geographic point You will need to enter the coordinates of the starting point of your path (or type its address), and the service will automatically lay the most optimal route to it, as well as indicate the approximate travel time and mileage.
Conclusion
If you need to search for your coordinates on Yandex Map, then it will be enough to enter the coordinates of the desired object in latitude and longitude in the search bar, and then press enter. If you just need to get the coordinates of the object you need, it will be enough to find it on Yandex.Map, click on it, and the required latitude and longitude coordinates will immediately appear in the appeared plate on the left.
Good day!

How to determine your coordinates and how to find an address by coordinates
I'll start with Google Maps, the official site :
To accurately determine your coordinates - click on the "Locate" button, usually a small window immediately pops up in the browser asking whether to allow access (select "Allow").
Important! By the way, in some cases, different services can 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, in Google maps, houses on this territory are not indicated at all) - then left-click on the point next to the one that Google defined - a small tab should pop up below, in which your coordinates!
Coordinates represent from itself two numbers. For example, in the screenshot below, these are: 54.989192 and 73.319559
Knowing these numbers, you can transfer 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, just open the maps and enter these two numbers in the search box (top left): after 1-2 seconds. a red flag will light up on the maps to indicate the desired point.
Note:
- coordinates must be specified with a dot, not a comma (correct: 54.989192 73.319559; incorrect: 54.989192 and 73.319559);
- specify the coordinates in the order in which the map gives 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 desired one ...);
- coordinates can be specified in degrees and minutes (example: 51 ° 54 "73 ° 31").
Yandex maps
By and large, the principle of operation is similar with Yandex cards. It is worth noting that if the address is not detected for one service, try using another. Sometimes, if a street or a district is not drawn in Google maps, then in Yandex, on the contrary, it is displayed quite fully, all streets are signed, and you can easily find out where to go and what to do.
Yandex maps also have specials. a tool that allows you to find out your location online (on the right, click on the arrow in the white circle, see the screen below).
To determine the coordinates - just click on the point on the map you need - a small window will pop up with addresses and two numbers - that's what they are.
You can insert both a specific address and coordinates into the search line (do not forget that you need to set them correctly: do not mix up the sequence, indicate through a period, not a comma!).
Addition!
I have another article of a similar kind on my blog - about determining the distances between cities, choosing the optimal road and estimating travel time. It will be useful to everyone who is going to go to another city, I recommend:
