What is Warp? What are the features?
A warp refers to a thread that connects two poles. Each meridian is a semicircle, and two opposing meridians of equal length (measurement) form a meridian coil, dividing the globe into two halves, and the distance between any two meridians (measurement) is not equal. The prime meridian is 0° and passes through the Greenwich Observatory in the United Kingdom.
What is Longitude? How is the East and West meridians divided?
The angle between the plane of the prime meridian and the plane of the local meridian is the longitude. From the prime meridian to the east to 180° for the east longitude, with"e"Denote; 180° west from the prime meridian is the west longitude"w"Denote;
What is Equator? What is Weft? What are the features?
The line that is at equal distance from the poles and perpendicular to the meridian is the equator and has a degree of 0*. The lines parallel to the equator are parallels, the coils of latitude are circles, and each parallel is of unequal length, (measured) the equator is the longest (measured). Decreasing (measured) from the equator to the poles, there are two parallels of the same degree, symmetrically distributed on both sides of the equator.
The equator divides the globe into two halves, with any two parallels at equal distances (measurements). Each parallel is perpendicular to the equator (measured).
How are southern and northern latitudes divided?
North of the equator is the northern latitude, used"n"Indicates that south of the equator is the southern latitude, with"s"Denote;

The meridian, also called the meridian, is a semicircular arc connecting the north and south poles, and the longitude is the angle between the meridian and the plane where the prime meridian is located. The meridian, also called the meridian, is a semicircular arc connecting the north and south poles, and the longitude is the angle between the meridian and the plane where the prime meridian is located.
Longitude, a geographical term, generally refers to the abscissa of the spherical coordinate system, specifically the degree to the east or west of a north-south alignment of a place on the earth called the prime meridian. According to international regulations, the longitude at the original site of the Greenwich Observatory in London, the capital of the United Kingdom, is set at 0° longitude, and then extends to the left and right.
The time zones are also divided into regions, with a difference of one hour every 15 degrees of longitude. As a basis of geography, longitude is the basic theory for understanding the rotation of the earth and the geographical division of regions, which needs to be carefully and accurately mastered.
From the North Pole to the South Pole, many large circles perpendicular to the Earth's equator in the north-south direction can be drawn, which are called "longitude circles"; The segments of these circles are called meridians. In 1884, it was internationally stipulated that the longitude passing through the former site of the Greenwich Observatory in the suburbs of London, England should be used as the starting point for calculating longitude, that is, longitude 0 degrees, 0 minutes and 0 seconds, also known as the "prime meridian".
To the east of it is the east longitude, a total of 180 degrees; To the west of it is the west longitude, which is 180 degrees Celsius. Because the earth is round, the longitude of 180 degrees east and 180 degrees west is the same meridian. The 180-degree longitude is designated as the "International Date Line".
In order to avoid using two different dates for the same region, the international date line is slightly deviated when encountering land.
The longitude of the other planets.
The coordinate systems of the planets are generally determined by their axis of rotation, and their starting points of longitude vary. In general, the starting point of the longitude of a planet with a fixed, observable solid surface is a surface feature, such as a crater, and the north pole is the pole that rotates towards the northern half of the solar system. The prime meridian of Mars, for example, passes through a crater called airy-0.

Latitude and longitude.
1. The law of latitude change: from the equator (0° latitude) to the south and north poles. The maximum latitude is 90 degrees, at the South Pole, the North Pole.
2. The latitude north of the equator is called north latitude, which is represented by "n"; The latitude south of the equator is called southern latitude and is denoted by an "s".
3. With the equator as the boundary, the earth is divided into two hemispheres, north and south, with the north of the equator being the northern hemisphere and the south of the equator being the southern hemisphere.
4. The change law of longitude: from the prime meridian (0° meridian) to the west and east to 180°.
5. The longitude east of the prime meridian is called east longitude, which is represented by "e"; The longitude west of the prime meridian is called west longitude, which is denoted by "w".
6. The dividing line between the eastern and western hemispheres is: a meridian coil composed of 20°W and 160°E.
West of 20°W to 160°E belongs to the Western Hemisphere (greater than 20°W or greater than 160°E).
East of 20°W to 160°E belongs to the Eastern Hemisphere (less than 20°W or less than 160°E).

1.Longitude is the coil that connects the north and south poles, which is divided into the eastern and western hemispheres by 160 degrees east longitude and 20 degrees west longitude, and increases to east from west to east.
Sutra, and vice versa, the West Longitude.
The latitude is very horizontal, the equator is 0 latitude, with the equator as the axis of symmetry, the closer to the two poles, the greater the number, the higher the latitude, 0 30 is the low latitude, 30 60 is the middle latitude, 60 90 is the high latitude 2Latitude degree range, 0-90...Longitude degree range, 0-180 degrees.
The 0 degree latitude is the equator. The 0 degree meridian is the prime meridian.
The meridian that passes through the former site of the Greenwich Observatory in the United Kingdom.
The latitude gradually increases from the equator to the south and north. The longitude gradually increases from 0 degrees of meridian to east and west.
The dividing line between the northern and southern hemispheres is the equator. The dividing line between the eastern and western hemispheres is 160°E and 20°W.
3.Most coordinate data expressed in latitude and longitude consists of two sets of numbers, generally speaking, the first set of numbers is longitude, and the last set of numbers is latitude. Longitude is generally from 0° 180°, divided into east longitude and west longitude, east longitude is represented by the prefix e (east) in the coordinates, and west longitude is represented by the prefix w (west) in the coordinates
The latitude is from 0° to 90°, divided into north latitude and south latitude, the north latitude is represented by the prefix n (noth) in the coordinates, and the southern latitude is represented by the prefix s (south) in the coordinates.
First of all, you need to know the North and South poles and the equator! >>>More
Same as Cartesian coordinate system.
First of all, it is explained that the theodolite positioning does not show longitude and latitude, but records the angle data from the observation point to the known reference, including horizontal and vertical angles. >>>More
Set up a pole and keep drawing its shadow, when the shadow is the shortest, the direction of the shadow is the standard north-south direction. Then, when the Sun is due south or north (depending on whether you are in the Northern Hemisphere or the Southern Hemisphere), measure the length of the shadow and pole and calculate the elevation angle of the Sun using trigonometric functions. Then look at the specific date of measurement, it is known that the sun directly hits the equator at the spring or autumn equinox, and the summer solstice or winter solstice directly hits the Tropic of Cancer back to the Tropic of Capricorn, and uses these known conditions and the specific date of the measurement day to interpolate the trigonometric function, and the modified value can be added with the elevation angle of the sun to obtain the local latitude value. >>>More
