Answer to a question from iWanderer. Our regular reader has a problem (the author's spelling has been preserved):

Look: I (for example) send you my geolocation. It is sent either through iM or through other messengers that support this function. But only the native Epol card produced by Tom-Tom is sent (we are talking about an iPhone). Or can I send another card? – if SOMETHING is possible, then the question is HOW – and then everything else is removed; if NOTHING, just your native one, then I guess you can somehow get the coordinates from there and enter them into a navigator from Yandex or 2GIS? What would you do? The practical application of this task is probably unnecessary to explain, however, it is worth noting that the native maps are still disgustingly drawn for the Russian Federation; somewhere locally Yandex rules, somewhere Google (I tried it in the Altai Mountains near Lake Teletskoye), somewhere (for example, the situation with the dacha community in the suburbs, described in those very comments) - undoubtedly 2GIS.)))

In this article we will learn how to send coordinates from 2GIS, Yandex Maps and Google Maps using instant messengers installed on your iOS device.

The GPS sensor in mobile devices can be used not only for its intended purpose (for navigation or determining coordinates), but also in a number of other, often not obvious at first glance, tasks.

Since in many cases several programs can perform similar tasks at once, it was given only for one or two, and the rest were listed in “Alternatives”.
Let me remind you that some features (sending coordinates, recording routes) are available in the composition, which were discussed a little earlier.
As usual, all the programs in the review are free, and some of them are available for other mobile platforms, so the material is of interest not only to Android owners.

COORDINATE TRANSMISSION

Simple but useful utilities for quickly transmitting your coordinates to other people.

PARENTAL CONTROL / COORDINATES OF FRIENDS




TRACKING

This section is dedicated to utilities that allow you to update your location information in real time and share it with other people. Similar functions, of course, can be obtained from utilities for finding a lost phone or parental control applications, but they are specialized for other tasks and therefore are not so convenient.

Glympse generates a special link to glympse.com (no registration required) that can be sent to someone via SMS, mail, or any other service installed on Android. The link opens a map in the browser, where the sender's position is displayed in real time.
The transfer of coordinates by default works for 30 minutes (the duration is configurable), after which the page stops updating. The user can also indicate the final destination of their route on the map so that they can be intercepted somewhere along the way.
Glympse is one of the most useful and interesting programs in the review, so it is not surprising that it is marked with the EDITORS' CHOICE badge in the Android Market.


The utility is designed specifically for fans of airsoft and paintball. BattleTac allows you to see the position of all players on your team on the screen and send quick messages and instructions to coordinate actions. The beta version of the program is distributed free of charge.


Alternative: Real Time GPS Tracker

ENHANCED REALITY


A FEW TIPS
If programs take a long time to determine the coordinates of the device in open space, we recommend that you first run the GPS Fix or GPS Test utilities, which you can read about above, or activate the ability to transmit data via GPRS/2G/3G channel. Believe me, it helps.
When recording routes far from civilization, it makes sense to switch the phone to Airplane mode to turn off the cellular module. Mobile communications in such places, as a rule, are practically unavailable anyway, but the saved battery charge may well be enough to continuously record a track throughout the whole daylight hours.
If you don’t have Internet access from your mobile device, but want to see your movement on a map in real time, you can use one of the programs that supports offline maps (for example, RMaps or Maverick).

Most companies indicate exact geographical coordinates near their address in their contacts. With their help, you can clarify the location of the organization, even if a person does not know where the object is located. To find the establishment, institution, or company you need, you will have to find out how to enter coordinates in Yandex.maps.

What do the numbers indicated in the coordinates mean?

On maps in Yandex, such numbers are presented in degrees in the form of a decimal fraction. It is customary in the world to use several more formats for displaying coordinates - minutes, degrees, seconds.

Coordinates are usually called a pair of numbers that determine the location of an object on the map.

  • The first number means latitude or the angle obtained between the zenith direction and the equatorial plane. Northern latitude is designated by the letter N, and southern latitude by S.
  • The second number means longitude (the angle formed between the plane of the meridian and the prime meridian). Longitude 0 - 180° towards the east of the prime meridian is called eastern (E), and to the western side - western (W).

About entering the required coordinates

To set longitude and latitude on maps, you need to find these parameters and click on them with the left side of the mouse. After this action, a hint about the name of the geographical object appears, and the required numbers appear below.


For example, in Saratov you need to find O. Yankovsky Square. After searching, click on it and the following information appears:

  • latitude – 51.533689;
  • longitude – 46.002794.

At the same time, Yandex maps help you build routes from any point to the desired location.

After opening the browser, type the phrase maps.yandex.ru in the address bar or immediately open the Yandex.maps application on your tablet (smartphone). Enter the coordinates in the search field and click on the “Find” button. To call up the search line, click on the magnifying glass icon. The format for entering coordinates assumes the following order: latitude – longitude. The whole part is separated by a dot from the fractional part. There should be no spaces between the numbers, and both numbers should be separated by a comma.

After clicking the “Find” button, the marker moves to the point describing the coordinates. The address and reflection in minutes, degrees and seconds appear on the left. If you type coordinates in the wrong sequence, you can quickly change the numerical order in Yandex.maps. To do this, click on the link called “Swap”, and the marker moves to the desired point.


Some electronic cartographic services and navigators operate with the sequence of coordinates: longitude - latitude. We hope that after reading this article it will become easier for you to navigate the space. If you do everything correctly, you can find the desired object on Yandex.Maps as quickly and easily as possible.

The easiest way for owners of Android smartphones is to use the Google Latitude service, which is built directly into Google Maps. It shows your friends' locations on the map. Moreover, their position can be viewed both through a mobile or tablet, and through the Latitude web interface on a computer.

To transfer your own coordinates through Latitude, you need to open Google Maps and select Latitude from the drop-down menu in the upper left corner. If this is the first time you launch the application, a notification will appear on the screen indicating that the device is invisible to others.


Then tap that message. This will open the Google Maps location settings menu. Turn on visibility of the gadget's location and GPS.


Now you need to add friends who can see the coordinates. To do this, go back to the Latitude menu and open Friends List. You can invite friends both from the phone book and via e-mail. As soon as someone accepts the offer, their coordinates will become visible on the map.


At this point, setting up the service is complete, and the coordinates of your friends are already shown on the map.


We have:
Google Maps app on your smartphone.
Mark a point on the map. What is important is the point outside the city. Those. this is not a street with a house under a specific number. This is either a point in the field or an exit from the highway. Well, in general, in the field. :-)
We mark this point as “My Places”.

Task:
transfer this point to another user.
Mark a specific place for him in the field/in the forest/on the highway.

Question?
How the hell can I do this?!

I was unable to obtain the coordinates of the point (in any system, no matter which one). I didn’t find how to do this on a smartphone.

Next, the “Send to friends” function.
A link is formed, but not the coordinates of the point. Using this link, the user gets anything, but not a specific point. He may get a point in a completely different place on the route.
He can get a point on the nearest street (if we are talking about the suburbs), but not the point that I marked.

Does anyone have any solutions? How can I transfer a point marked on Google Maps to another user?

How to find out the coordinates of a place

The way you get coordinates is different in new and classic Google Maps. Also note that you cannot find out coordinates using a smartphone or tablet.

New interface

Click on the desired area of ​​the map with the right mouse button.
Select the What's here? item from the menu.
A panel with coordinates will appear under the search bar.

Classic interface

Open Google Maps.
Click on the desired area of ​​the map with the right mouse button.
Select the What's here? item from the menu.
The coordinates will appear in the search bar (at the top of the page).

In one of the articles we looked at the question of how to determine your coordinates and tell them to a friend. By the way, a very popular article.

Now consider the inverse problem. Let's say you received an SMS message or an email or a message from some messenger from a lost friend, in which he reports the coordinates of the place where he is and asks you to drive up to him and help him out.

What do you need to do? The answer is very simple: you need to use, for example, the application GoogleTOarts or YandexTOarts(you can download and install them using the links provided), enter the received coordinates in the search bar, find this place on the map and get directions using these applications. Let's see how it's done.

Yandex maps

1. When opening the application, the system determines your location and shows this place in the center of the map. In this case there should be GPS enabled navigation ( Geodata in the curtain).

2. In the bottom line, click Search.

3. In a new window enter in sTRoku Search the coordinates you received. You need to enter them definitely in this form : only in the form of decimal numbers (without any degrees, minutes and seconds) separated by a dot, first latitude, then longitude and with a comma between them. For example, like in the screenshot: 60.0, 30.3 Press on the on-screen keyboard Search. The found location appears in the center of the screen in the form of a mark.

4. Click below Finding a route. The application finds route options (you can choose for car or public transport) and, when the Internet is turned on, taking into account current traffic jams.

5. Select the one you need and click yellow arrow in the upper right corner or option Travel with Yandex navigator. And you go, you meet a friend who is waiting for you and says thank you. :)

Google Maps

The steps are almost the same as those described above. I provide explanatory screenshots.

1. Open Maps, enter coordinates in the search bar.

2. Click the car icon in the lower right corner. Choose the type of transport.

3. Choose one of the proposed routes. Click on the arrow icon in the lower right corner.

4. You are driving, walking, etc.

AND one more note. If in a friend’s message the coordinates are given in as a link like http://maps.google.com/maps?q=loc:60.0,30.3, then everything is much simpler and faster: you just need to click on the link and select Open URL. This will automatically open the Google Maps application (if it was installed by default for such links) or a browser window with maps and the desired point will be in the center. And then everything is as described above: we are looking for a route, etc.

If in the found area there are no roads, there are no pedestrian roads (for example, in a forest) and it is not possible to automatically build a route, then, seeing your position and the position of a friend on the map, you can simply go "in azimuth". :) But it is clear that a friend should in any case remain at the point whose coordinates he gave you. Warn him about this by phone or ask him for new coordinates.

Good luck to you, see you again on the pages of my site.

Yandex Maps as a search information mapping service was first launched in 2004. Five years later, pre-camera street panoramas began to be added to the maps, which provided a new qualitative breakthrough in the field of cartography and terrain orientation. With the help of panoramas, people have unlimited opportunities for virtual “travels” to places of interest without leaving home and having only broadband access to the Internet.


Currently, Yandex maps are also the basis for two very useful services for drivers, namely Yandex.Navigator and Yandex.traffic. They are especially useful for residents of large cities with high traffic congestion.

All objects on maps are plotted using a coordinate grid, and in order to indicate the exact location of an object and eliminate discrepancies in this matter, they often use an indication of the coordinates to which this object is attached. Therefore, the task arises with regular intervals, which is to find a place on the map using its coordinates.
For people who have forgotten their high school geography course on the basics of using cartographic data, such a task can be perplexing. Therefore, in this article we will talk about how to enter coordinates into Yandex maps and find the place you are interested in on them.

How are coordinates set on maps?
First you need to understand the principle of operation of the coordinate grid. Each point on the map is specified using two coordinates that determine its position on the plane. These coordinates are called longitude and latitude and can have different forms of representation.

After we have dealt with the minimum knowledge necessary for the search, we can begin to solve the main problem.

The coordinates should be entered in exactly the same order as they are given in the example above. First, the latitude is indicated, and then, separated by a comma, the longitude in any format. Moreover, this can be done on the maps themselves by entering the coordinates in the search bar.


So, using the main page of the Yandex search engine.


Trained algorithms will recognize what you want to get in the search results and immediately above the search results will display a map insert with the search location indicated on it. From this insert you can switch to the traditional map by clicking on the button To the big map.

In some cases, the letters N and E are also added to the record of coordinates in degrees, minutes and seconds at the end so as not to confuse latitude with longitude, as a result of which it takes the form 45°2′10″N, 38°58′28″E. This form of recording coordinates is also successfully recognized by Yandex.

If, as a result of searching by coordinates in Yandex Maps, you see something different from what was expected, then most likely you have mixed up the latitude and longitude. The fact is that some map services use a different standard and use longitude as the first value. In this case, you need to swap the coordinates and do a new search using the corrected coordinates.

On Yandex Maps, geographic coordinates are recognized in degrees, presented as decimal fractions. At the same time, several other formats for recording coordinates are used in the world, for example, in degrees, minutes and seconds.

Coordinates are a pair of numbers that determine the location of an object on the map.

The first digit in the format adopted on Yandex Maps is , or the angle between the local zenith direction (that is, the direction pointing directly upward over a specific location) and the plane of the equator. Northern latitude is designated by the letter N, southern latitude by the letter S.

The second number is longitude, or the angle between the meridian plane (the line of section of the surface of the globe by a plane passing through a given point and the axis of rotation of the Earth) and the plane of the initial prime (Greenwich) meridian. Longitudes from 0° to 180° east of the prime meridian are called eastern (E), and to the west - western (W).

Entering coordinates on Yandex Maps

Open your browser and type maps.yandex.ru in the address bar, or open the Yandex Maps application on or. Enter the coordinates in the search bar, for example: 55.751710,37.617019 - then click “Find”. In the application, to call up the search bar, you must first click on the magnifying glass icon (usually located at the bottom of the screen). Please note that the format for entering coordinates should be exactly this: first latitude, then longitude; the integer part of the coordinates is separated from the fractional part by a dot; numbers do not contain spaces; latitude and longitude are separated by a comma.

After clicking on the “Find” button, the marker on the map will move to the point that the coordinates describe - now you can build a route.

To the left of the map, the address corresponding to the coordinates will be displayed, as well as an alternative representation of them - with degrees, minutes and seconds. In our case it will look like this:
Latitude: 55°45′6.16″N (55.75171)
Longitude: 37°37′1.27″E (37.617019)

If you enter coordinates in the wrong order - for example, first longitude and then latitude (some navigators and other electronic mapping services work with data in exactly this sequence) - on Yandex Maps you can quickly change the order of the numbers. To do this, click on the “Swap” link under the full description of the coordinates, and the marker will move to the correct point.

Every point on the surface of the earth has longitude And latitude. If you find these values, you can determine the geographic coordinates of the object. If you find yourself in an unfamiliar area and lose landmarks in the form of a high hill or a noticeable tree, calculate to find them on the map. A map and compass will help you find your way back.

You will need

  • - watch;
  • - protractor

Instructions

First you must determine geographic longitude. This value is the deviation of an 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 west of Greenwich, it is called longitude. One degree is equal to 1/360 part.

Find 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.

Subtract 12 from the result obtained. Convert this difference to degrees. 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°.

Remember, if local noon occurs before noon GMT, this is longitude; if later, it is . 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 (latitude) side, from 0° to 90°.

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.

The Google Maps service allows you to find a place on the map not only by keywords, but also directly by GPS coordinates. This is convenient if your navigator is not connected to your computer, but you need to show a fragment of the map on a large screen.

Instructions

Go to the following site:

http://maps.google.com

On or with a built-in navigation receiver, find an item in the menu that allows you to display digital coordinate values ​​​​on the screen ( ). For example, in Nokia devices the location of this item may be as follows: “Applications” - “Location” - “GPS Data” - “Position”. Wait until the device finds the signal and calculates

To find a certain object in a city, in most cases it is enough to know its address. Difficulties arise if you need to explain where, for example, an unnamed building in an industrial zone, a summer cottage, or a place in the forest is located. A universal means of indicating location is geographical coordinates.

In modern navigation it is standard to use world coordinate system WGS-84. All GPS navigators and major cartographic projects on the Internet operate in this coordinate system. Coordinates in the WGS-84 system are as commonly used and understood by everyone as universal time.

Public Accuracy when working with geographic coordinates is 5 - 10 meters on the ground. You can indicate, for example, not just a site, but a specific place of entry to it - a gate, etc.

Two coordinates - latitude And longitude- determine the position of a point on the earth’s surface. The coordinates are angular values ​​and are expressed in degrees. North latitude and east longitude are considered positive numbers, south latitude and west longitude - negative.

Examples of geographic coordinates (latitude, longitude): 55.717169, 37.930262 (Kozhukhovsky shelter); 21.36214, -157.95341 (Battleship Missouri, Pearl Harbor); 54.057991,33.678711 (Unnamed height).

How to determine the geographic coordinates of a place on a map

2. Using the search, find the required (nearest) locality. For cities, you can try adding a street or house to the request.

3. Find the desired location on the map.

4. Turn on the “Satellite” or “Hybrid” mode and gradually zoom in on the desired area of ​​the terrain until individual buildings and other landmarks are comfortably visible (if possible).

5. Get geographic coordinates:

(Google Maps) Right-click on the desired location on the map and select “What’s there?” from the menu that opens. A panel with the address and geographic coordinates will appear at the bottom of the map.

(Yandex.Maps) Right-click on the desired location on the map and select “What’s here?” from the menu that opens. Geographic coordinates will appear in the search bar of the map (as well as in the panel on the right).

(Bing Maps) Right-click on the desired location on the map and select "Add Pin" from the menu that opens. A panel with the address and geographic coordinates will appear below the search bar. When recording coordinates, you may have to replace commas with dots.

PLEASE NOTE: point 4 is fundamentally important - a satellite image provides the most accurate geographic coordinates. If the maps you are using for a given area do not have a high-quality satellite image, try other maps.

How to find a place on the map by geographic coordinates

2. Paste the coordinates into the search bar and click "Search".

Geographic coordinates and GPS navigator

Geographic coordinates can be directly (in the form of numbers) entered into a GPS navigator and read from it. Usually the coordinates are entered into a new waypoint, which is then navigated to, or can be navigated search by coordinates. The current location is usually captured as a waypoint from which coordinates can later be read.

Before operation, the appropriate coordinate format in the navigation program settings - in degrees ddd.ddddd° (see section "Forms for recording geographic coordinates"). An attempt to enter coordinate numbers in an inappropriate format will result in a gross navigation error.

Illustrations: choosing the coordinate format in the navigation program settings; waypoint in GPS navigator; current coordinates on the navigator screen (Navitel).

1. On Google Maps (Classic), search for coordinates.

2. Select the desired position and scale of the map, if necessary, turn on the “Satellite” mode.

This publishing method is good because even a completely untrained user can open the link. At the same time, the numerical values ​​of the coordinates remain available (they can be seen in the search bar of the map that opens via the link). In addition to the coordinates, the link also remembers the current state of the map - scale, position, Satellite mode.

Geographic coordinates and route planning

Geographic coordinates can be used to specify the start, end, and intermediate points when building routes on Google maps. Please note that the point markers shown on the map are tied to roads, and their position corresponds only approximately to the entered coordinates.

Forms for recording geographic coordinates

Geographic coordinates are signed numbers (latitude from -90° to +90°, longitude from -180° to +180°) and can be written in various forms: in degrees (ddd.ddddd°); degrees and minutes (ddd° mm.mmm"); degrees, minutes and seconds (ddd° mm" ss.s"). The recording forms can be easily converted into one another (1 degree = 60 minutes, 1 minute = 60 seconds) To indicate the sign of the coordinates, letters are often used, according to the names of the cardinal directions: N and E - northern latitude and eastern longitude - positive numbers, S and W - southern latitude and western longitude - negative numbers.

An example of different forms of recording the same coordinates:

21.36214, -157.95341
N21.36214, W157.95341
21.36214°N, 157.95341°W
21°21.728"N, 157°57.205"W
21°21"43.7"N, 157°57"12.3"W

The form of recording coordinates in DEGREES is most convenient for manual entry and coincides with the mathematical notation of a number. The form of recording coordinates in DEGREES AND MINUTES is preferred in many cases; this format is set by default in most GPS navigators and is standardly used in aviation and at sea. The classic form of recording coordinates in DEGREES, MINUTES AND SECONDS does not actually find much practical use.

Google Maps allows the use of almost any form of coordinate recording in search queries, and the symbols of degrees, minutes, and seconds can be REPLACED WITH SPACE.

Accuracy of determining geographical coordinates

A classic GPS receiver (SiRFstar III chip with Static Navigation mode disabled) provides coordinate determination accuracy in open areas of 5 - 10 meters. Recently, there has been a tendency to use, even in expensive devices, rather mediocre GPS receivers, with accuracy coarsened to 30 - 50 meters. In urban areas, the error of any GPS can be tens or hundreds of meters.

The accuracy of determining coordinates from maps on the Internet is limited by the accuracy of georeferencing satellite images. According to practical observations, for Google maps in the Moscow region, the error in georeferencing satellite images usually does not exceed several meters.

How many kilometers are in 1 degree of latitude and longitude?

1 degree of LATITUDE corresponds to approximately 111 km.

1 degree of LONGITUDE corresponds to approximately 111 km at the EQUATOR; when moving towards the poles, the corresponding distance decreases in proportion to the COSINE OF LATITUDE. For example, for Moscow, 1 degree of longitude is 111 km * cos(55.7°) ≈ 62 km.

From these relations it can be determined, for example, that recording coordinates in degrees with 6 digits after the decimal point provides an accuracy of the order of 111 km * 0.000001 ≈ 0.1 meters on the ground, which is obviously excessive.

Rounding the coordinates to a whole number of seconds gives an accuracy of the order of 111 km / 3600 ≈ 30 meters.
