How to determine the latitude and longitude of your position?
Anywhere on the earth, as long as you have a watch, a bamboo pole and a tape measure, you can know the local latitude and longitude.
However, this form must be checked with national standards on time. The method is as follows: 1. Count two days first. For example, in a place in China, at noon, the shortest time of pole shadow is 13: 20, and the ratio of pole length to shadow length is 1, then we can know that this place is 45 north latitude (TG α =1) and east longitude 100 (from 6544.
2. The longitude calculation algorithm from two days to one day is that the constant latitude is α+23.5 in the winter solstice and α-23.5 in the summer solstice in the northern hemisphere, which can be added or subtracted on any day. 3. Correction value algorithm: that is, the difference between two minutes and two days multiplied by 94/365. For example, today is February of 17, which is 33 days different from the vernal equinox on March 22, that is, the direct point of the sun is 33 * 94/365 = 8.5 south latitude, so the latitude obtained at noon today is (arc TG α+8.5) TG α =
Know the latitude and longitude how to query the actual location?
Knowing the latitude and longitude can locate this place on the map, which is very easy to operate. At present, Google Maps and Google Earth can be realized.
Google Maps, Google Earth
Methods/steps
Generally, the latitude and longitude measured by mobile phone or GPS are in the front and the latitude is in the back. When using map search, latitude comes first and longitude comes last.
Open Google Maps and enter the latitude and longitude in the search box, separated by English ",". Click search. come here
Latitude and longitude: for example, 3 1. 19243, 12 1.54044. The result is shown in the figure. But the positioning of Google Maps is not very accurate.
The most accurate method is to use Google Earth software. Open Google Earth and enter the latitude and longitude at the icon position in the upper left corner. Pay attention to the need to ensure normal network connection.
After clicking search, Google Earth will slowly enter the actual location of latitude and longitude. This position is very accurate, unless your latitude and longitude itself is biased.

Latitude and longitude calculation
The azimuth angle θ in topographic survey is based on the true north (n) axis (usually the Y axis in rectangular coordinate system, designated as the X axis here; The original X-axis is defined as Y-axis, and the Y-axis is defined as the starting edge (in the horizontal direction of east (e) and west (w)) rotating clockwise to the ending edge AB, and point A is the vertex of the angle, which is denoted as αAB and θ=αAB.
090 180 270 is converted according to 1 = 60' (minutes) and 1' = 60 "(seconds).
Calculate the distance between any two points on the earth according to their latitude and longitude.
The earth is a nearly standard ellipsoid with an equatorial radius of 6378. 140km, a polar radius of 6356.755km and an average radius of 6371.004km. ..
The latitude and longitude of a is (LonA, LatA), and the latitude and longitude of the second point b is (LonB, LatB).
The latitude and longitude of point a are m, n, lona = m and lata = n, respectively.
Let AB=s (length, meter), the distance difference between north and south is x, and the distance difference between east and west is y,
When the longitude of the earth is * * * 360, east longitude 180 and west longitude 180, the longitude passing through Greenwich Observatory in London is 0;
Latitude takes the great equatorial circle as 0, 90 north latitude to the North Pole, and 90 south latitude to the South Pole. Latitude is a circle parallel to the great equatorial circle.
The distance between the meridians decreases every 1 longitude difference, the radius of the meridian circle at different latitudes is set as r, the central angle is latitude n, and the circumference L of the latitude circle is calculated according to the average radius of the earth.
R = 6371.004km * sine (90-N)
L=2πr，
L= L/360=2πr/360 per north latitude 1 longitude.
Longitude δ (m) = y/(l/360) = y/(2π r/360) = 360y/(2π r)
LonB=m+δ(m)，
The length per 1 latitude is fixed as 1 10.95km.
The latitude δ (n) corresponding to the north-south distance difference x = x/(110950/1).
LatB = n+δ(n)
The latitude and longitude of point b is b (lonb, latb) = b (m+δ (m), n+δ (n)).
Pay attention to the size of θ, the position of point B at point A,
If δ(m) and δ(n) are calculated in absolute values, pay special attention to the preceding symbols.
When B is south of A, δ (n) is negative; When B is to the west of A, δ(m) is negative.
How to express latitude and longitude?
Latitude and longitude are expressed in degrees, which can be directly expressed in decimal points, but the decimal points of degrees can also be divided into angular minutes (1 angular minutes equals one sixtieth degree) and seconds (one second equals one sixtieth minute). There are many ways to express latitude and longitude. Here are some examples.
1, degrees, minutes, seconds (degrees, minutes, seconds) -49 30' 00 "-49 d30m00s
2. Minute means (degree: minute)-49 30.0'-49 d30.0m.
3. Degree means -49.5000-49.5000 d (usually with four decimal places).

The longitude is divided into 360 degrees, and there are 1 time zones every 15 degrees, where 0 degree is called the prime meridian, which is the first place to enter a new day, and then every 1 time zone difference to the west is 1 hour. For example, it's 5: 00 a.m., so one time zone in the west is 4: 00 a.m., and the other time zone 1 is 3: 00 a.m., and so on, and the east is just the opposite, all the way to the prime meridian, which means that the difference between the two sides of the prime meridian is just 23 hours.
Latitude and longitude 1 degree =60 minutes =3600 seconds. This hexadecimal system was customized by the Babylonians, and we still use it today, as long as the angle and circle are the same.
Latitude refers to the line-plane angle between a point and the center of the earth and the equatorial plane of the earth, and its value is between 0 and 90 degrees. The latitude of the point located north of the equator is called north latitude, which is denoted by n, and the latitude of the point located south of the equator is called south latitude, which is denoted by s.
Areas with latitudes between 0 and 30 degrees are called low latitudes, areas with latitudes between 30 and 60 degrees are called middle latitudes, and areas with latitudes between 60 and 90 degrees are called high latitudes.

The approximate latitude and longitude range of China.
Longitude range of China: East longitude 73 33' to135 05'; Latitude range: 3 565 438+0 ′ n to 53 33 ′ n. The letter e stands for east longitude; The letter n stands for north latitude. East longitude is positive and west longitude is negative; North latitude is positive and south latitude is negative.
Latitude and longitude are the combined names of longitude and latitude, which form a coordinate system. Known as the geographical coordinate system, it is a spherical coordinate system that uses the sphere of three-dimensional space to define the space on the earth, and can mark any position on the earth. Latitude and longitude are expressed in degrees, which can be directly expressed in decimal points, but the decimal points of degrees can also be divided into angular minutes (1 angular minutes equals one sixtieth degree) and seconds (one second equals one sixtieth minute).

In field coordinates, latitude and longitude can represent the range of a region or country, which is a more accurate and intuitive concept. For example, the East China Sea air defense identification zone divided by China a few years ago has great demonstration significance. Identification area: 33 degrees north latitude 1 1 min, 47 minutes east longitude1min, 33 degrees north latitude1min, 0/25 degrees east longitude, 00 minutes north latitude.
Longitude is vertical and latitude is horizontal. The first step is to judge the codes of east-west longitude and north-south latitude (which is also the most critical step). Judging basis: Looking at the figures, the east longitude (E) is getting bigger and bigger, the west longitude (W) is getting bigger and bigger, the north latitude (N) is getting bigger and bigger, and the south latitude (S) is getting bigger and bigger. Practice: The arrow points to the corresponding latitude and longitude. The second step: the method of judging the direction: the meridians point to the east and west (absolute direction). For example, judge which direction point A is located at point C, mark the east, west, north and south at point C, and then see which direction point A is located at point C. Step 3: judge the east, west, north and southern hemisphere according to the latitude and longitude, and judge the formula of the east and west hemispheres: the longitude is less than 20 degrees, and they are all in the eastern hemisphere; Longitude greater than 160 degrees, all in the western hemisphere; Longitude is between 20 degrees and 160 degrees, east longitude is in the eastern hemisphere, and west longitude is in the western hemisphere.
Latitude and longitude calculation method
Hello! The method is as follows: 1. Count two days first. For example, in a place in China, at noon, the shortest time of pole shadow is 13: 20, and the ratio of pole length to shadow length is 1, then we can know that this place is 45 degrees north latitude (TG α = 1) and east longitude 100 (from 65430. A special angle is used here. 2, and use the algorithm to calculate the longitude of two days. The constant latitude of the northern hemisphere is α+23.5 in winter solstice and α-23.5 in summer solstice. 3. Correction algorithm: the difference between two minutes or two days is multiplied by 94/365. That is, the direct point of the sun is 33 * 94/365 = 8.5 south latitude, so the latitude obtained at noon today is (arc tgα+8.5) tgα = latitude and longitude of rod length/shadow length. The converted latitude and longitude can be expressed in degrees, which can be directly expressed in decimal points, but the decimal points of degrees can also be divided into corner points (1 corner point is equal to one sixtieth degree). And seconds (one second equals one sixtieth of a minute). There are various patterns of latitude and longitude. Here are some examples. The meaning of degrees, minutes and seconds is (degrees: minutes: seconds) -49 30' 00 "- 123D 30m00 s degrees mean (degrees: minutes) -49 30.0'-65438+.
How to distinguish between latitude and longitude?
Most coordinate data expressed by latitude and longitude are composed of two groups of numbers. Generally speaking, the number written at the front is longitude, and the number written at the back is latitude. Longitude is generally between 0 and 180, which is divided into east longitude and west longitude. East longitude is indicated by the prefix e (east) in the coordinates, and west longitude is indicated by the prefix w (west) in the coordinates. Latitude varies from 0 to 90, which is divided into north latitude and south latitude. North latitude is denoted by the prefix n (north) in coordinates, and south latitude is denoted by the prefix s (south) in coordinates. First, there is a prefix. Simply put, if there is a prefix, you can distinguish the latitude and longitude according to the prefix. If the prefix is e or w, it must be longitude, if the prefix is n or s, it must be latitude (for example, E 78 36'). Secondly, if there is no prefix, it can be divided into the following situations: First, if there is no prefix, you must know which hemisphere the coordinate is located in, or where it is, such as whether it belongs to the west of the northern hemisphere or the east of the southern hemisphere. Otherwise, there will be four groups of data, which cannot be judged! Let's make it clear. Look down: 1) If a set of numbers exceeds 90, then this set of numbers must be longitude (because latitude cannot exceed 90), for example, 1 13 36' 43 ",43 56' 32", with longitude in the front. For example, the coordinates 48 36 ′ 43 ″ and 43 56 ′ 32 ″ are known, so we can first look at where E48 30 ′ 00 ″ and N43 30 ′ 00 ″ are. If they are close to this coordinate, the front must be longitude, otherwise it is longitude. 4) The two sets of coordinates are the same, so this need not be explained. That's longitude and that's latitude, which doesn't seem to mean much. Third, there is an extreme situation. Just give a set of numbers and know where the coordinates are. Refer to the method without prefix 2! If there is no prefix, I won't tell you where it is. Go to the person who gave you the coordinates at once and slap him! Knocked for a long time, (I deleted it by mistake once when it was almost past% > _ User reported it on 20 17- 10-08.
How to identify latitude and longitude?
How to identify latitude and longitude? The earth is round. On the map, the vertical line in the north-south direction is longitude. The horizontal line in the east-west direction is latitude Latitude is bounded by the equator, which is parallel to the equator. It is called latitude in the north and latitude in the south. The equator is 0 degrees, the North Pole is 90 degrees north latitude, and the South Pole is 90 degrees south latitude. With Greenwich Observatory in London as the boundary, the eastern half is called the Eastern Hemisphere and the western half is called the Western Hemisphere. Lines perpendicular to latitude are called meridians. Greenwich Observatory has a longitude of 0 degrees, and east longitude 180 degrees and west longitude 180 degrees are the same line. The world is 360 degrees, and the two hemispheres are 180 degrees respectively. The world is divided into 24 time zones, and there are 12 time zones in the eastern and western hemispheres, and each time zone is 360/200.
