Question of latitude and longitude, please enter the geography and astronomy.

If you follow the degree (°) minute ('), seconds (") is measured in the sexagesimal system, i.e., 1 degree (°) = 60 minutes ('), 1 point (') = 60 seconds ("）。

Therefore, if the number required to be filled in the software is 6 into 1 degree after the decimal point, it is accurate to 10 points, and the measurement method found on the web page is accurate to the degree. The conversion is very simple, multiply the number after the decimal point of the data found on the web page by 60, and then divide by 10, and the number obtained is the number that should be filled in after the decimal point in the software.

If it involves a second to calculate, if the landlord can't calculate, he can directly send the data to me, and I can help the landlord calculate it.

The equator is the longest latitude, passing through 14 countries: Indonesia, Nauru, Kiribati, Ecuador, Colombia, Brazil, Gabon, Congo (Brazzaville), Congo (DRC), Uganda, Rwanda, Kenya, Somalia, Maldives and other 14 countries;

There are fewer countries in the southern hemisphere, so there should not be more parallels in the southern hemisphere than in the countries that cross the equator, and there are more countries in the northern hemisphere, especially in Europe, so you can pay attention to the parallels that pass there.

The Tropic of Cancer crosses 13 countries, including China, Myanmar, India, Bangladesh, Oman, the United Arab Emirates, Saudi Arabia, Egypt, Libya, Algeria, Morocco, the Bahamas, and Mexico.

8 Important Meridians The prime meridian passes through the upper reaches of the Niger River in England, France, and Africa.

At 30°E, it passes through Finland, Turkey, Egypt, and South Africa.

At 60° east longitude, it crosses the Ural Mountains, Kazakhstan, Iran, the Arabian Sea.

The 90° east longitude passes through the Yenisei River, the Altai Mountains, the Tien Shan, the Tibetan Plateau, and Bangladesh.

At 120°E, it passes through the Lena River, Hulunbuir Grassland, the Bohai Sea, the Shandong Peninsula, Hangzhou, the Taiwan Strait, and western Australia.

180° through the Aleutian Islands in the Pacific Ocean, east of the two islands of New Zealand South and North.

120°W longitude through Canada, the western United States.

At 60° west longitude, it passes through the island of Newfoundland, the Amazon Plains, and the Argentine Pampas. Six-in-one is measured in degrees, minutes, and seconds, and decimal one is the usual meaning of "a few degrees", and the unit is simply "degrees".

Six-in-one is measured in degrees, minutes, and seconds, and decimal one is the usual meaning of "a few degrees", and the unit is simply "degrees".

The geocentric latitude and longitude is more than the astronomical latitude and longitude and the latitude and longitude of the earth, and the correction of the radius of the earth at each point.

The astronomical latitude and longitude are determined based on the actual topography of the earth, which can be said to be a coordinate in measurement.

The latitude and longitude of the earth ignores the specific topographic conditions, and instead idealizes the earth as the closest ideal ellipsoid, and then determines the latitude and longitude.

The latitude and longitude of the earth is the combined name of the longitude of the earth and the latitude of the earth.

The surface of the earth is an irregular surface, and it is conceived as a spheroid that is closest in size and flattening to the earth, called an earth ellipsoid.

The plane that passes through the center of the earth's ellipsoid and is perpendicular to its axis of rotation is called the ellipsoidal equatorial plane, and the line that intersects it with the earth's surface is called the equator;

Through a certain point on the ground and the plane of the axis of rotation of the earth's ellipsoid, it is called the meridian of the earth at a certain point.

The angle between the meridian of the great grip forest and the meridian of the beginning of the earth at this point is called the longitude of the earth.

The angle between the normal of the Earth's spheroid and the plane of the equator through this point is called the geodetic latitude.

Astronomical latitude and longitude refers to the latitude and longitude based on the plumb line at a certain point on the ground and the axis of rotation of the earth.

The plane containing the plumb line at a point on the ground and the earth's axis of rotation is called the astronomical meridian, the angle between the meridian and the prime meridian is called astronomical longitude, and the angle between the plumb line and the earth's equatorial plane is called astronomical latitude.

Latitude and longitude is the combined name of the longitude of the center of the earth and the latitude of the center of the earth. The plane that contains the line between the center of the earth and the axis of rotation of the earth at a certain point on the ground is called the geocentric meridian.

The angle between the geocentric meridian and the prime meridian is called the geocentric meridian section of Kaimu.

The angle between the line with the center of the earth and the equatorial plane of the earth is called the latitude of the center of the earth.

The same longitude, determined by latitude, both in the northern and southern hemispheres. The parallel, like the meridian, is an auxiliary line assumed by humans for the convenience of measurement, and is defined as the trajectory formed by the rotation of the earth at a point on the earth's surface.

Any one of the wefts is round and parallel to each other. The length of the parallels is the circumference of the equator multiplied by the cosine of the latitude of the parallel, so the equator is the longest, and the farther away from the equator, the shorter the circumference, and it shrinks to 0 at the poles. From the equator to the north and south, each 90°, is called the north and south latitudes, which are denoted by "n" and "s", respectively.

The longitude of a place generally corresponds to the time difference between it and UTC: there are 24 hours in a day, and a circle has 360 degrees, so the Earth rotates 15 degrees per hour. So if a person's local time is 3 hours ahead of UTC, then he is about 45 degrees east longitude.

However, since there is also a political factor in the division of time zones, the time zone in which a person is located does not necessarily correspond to the above calculations. But by measuring the time of place, a person can calculate the longitude of the place where he is located. In order to calculate this data, he needed a clock that indicated the coordinated universal time and needed to observe the time of the sun's meridian circle.

Latitude-related; In the winter half, the higher the latitude in the Northern Hemisphere, the earlier it gets dark.

Related to longitude, the sunrise is seen earlier in the east, so the sunset is also seen earlier.

The same longitude, determined by latitude. Whether it is in the northern and southern hemispheres, in the local summer, it gets dark early in the low latitudes, and it gets dark late in the high latitudes, and the polar regions will even have no sunset for the whole day or even half a year; In the local winter, on the other hand, it gets dark late in the low latitudes, and it gets dark early in the high latitudes, and the polar regions even have no dawn for the whole day or even half a year.

In the case of the same latitude, it is determined by longitude, and both sunrise and sunset in the western time zone are later than in the eastern time zone.

The same latitude, determined by longitude, east, early sunrise, early dark;

The same longitude, determined by latitude, the higher the latitude in winter, the earlier it gets dark, and in summer, the lower the latitude, the earlier it gets dark.

The latitude and longitude of the earth refers to the one drawn in the globe, the horizontal one is called latitude, and the vertical one is called longitude. With the earth as the center, project the sky onto a large sphere, that's what you say"Astronomical latitude and longitude" - right ascension and declination are the same as the latitude and longitude of the earth.

The term "geographic latitude" refers to ().

a.The angle of intersection of the normal of a point on the Earth with the equatorial plane.

b.The angle between a point on Earth and the geocentric line and the equatorial plane.

c.The angle at which a point on the elliptical meridian of the Earth and the geocentric line meet the equatorial plane.

d.The intersection of the normal of a point on the elliptical meridian of the Earth's ellipse and the equatorial plane.

Correct answer: The angle of the intersection of the Fameng answer line and the equatorial plane at a point in the elliptical meridian of the earth.

Summary. Hello friend<>

The reason for the wide range of astronomical observations at low latitudes is due to the low influence of the atmosphere, the wide field of view, the geographical location of the observatory and the long astronomical observation time.

The reason for the wide range of astronomical observations at low latitudes.

You are <> good friend

The reasons for the wide range of astronomical observation at low latitudes are: the small influence of the atmosphere, the wide field of view, the geographical location of the observatory, and the long time of liquid hand astronomical observations.

Why does it take a long time to observe at low latitudes.

The long observation time at low latitudes is due to the influence of the Earth's rotation and revolutional motion.

In addition, observers near the equator can observe the entire sky, and since the circumference near the Earth's equator is the longest, this area has the longest observation time.

Does precipitation at low latitudes affect the observation time?

Good precipitation at low latitudes can affect the observation time.

When the amount of precipitation is high, the observation time will be shortened and the observation quality will decrease.
