Where is the origin of China s land? As the origin of our country s earth, what is the role?

The origin of China's land, located in Xianyang City, Shaanxi Province.

Jingyang County (Jinggan Town) Yongle Town, Shijisi Village. It is about 36 kilometers away from the urban area of Xi'an in the south.

The origin of the Chinese earth is not the geometric center of China, but the datum point of the national geographic coordinate system of China. According to reports, in the early days of the founding of the People's Republic of China, the geodetic coordinate system used in China was from the former Soviet Union.

The origin of its coordinates is Bohr in the former Soviet Union.

Kofu Observatory.

China's own earth origin is built in 1978, the origin of the stone is hewn with a whole piece of granite, weighing 7 tons, there is a fingernail size of the red agate ball on it, the cross point engraved on the agate ball is the "origin" of the Chinese land, is the starting point and reference point of the latitude and longitude coordinates of the Chinese land.

It is located in Beiliu Village, Yongle Town, Jingyang County, Shaanxi ProvinceThe origin of the earth of the People's Republic of China, the origin of the earth, also known as the datum point of the earth, is the starting point and datum point of the national geographic coordinates - latitude and longitude. The origin of the earth is an artificially defined point, which is the use of Gaussian is the method of using Gaussian plane Cartesian coordinates to establish a unified national coordinate system, and the "1980 National Geodetic Coordinate System", referred to as the "80 system", is also known as the "1980 Xi'an Coordinate System". In the 70s of the 20th century, China decided to establish its own independent geodetic coordinate system.

Through field investigation and comprehensive analysis, the origin of China's land was finally determined in Beiliu Village, Yongle Town, Jingyang County, Shaanxi Province.

The entire facility of the origin of the earth is composed of four parts: the central sign, the instrument table, the main building, and the projection table. The three-dimensional building more than 25 meters above the ground has a total of seven floors, and the top floor is the observation room, which is equipped with an instrument table; The top of the building is a monolithic semi-dome made of fiberglass, which can be turned over electronically for observation of celestial bodies; The central sign is buried in the basement of the main building**.

The origin of the earth plays an important role in China's economic construction, national defense construction and social development.

The original land of our country is located in Shijisi Village, one of the many villages in Shaanxi Province. This is an artificial fixed point, and the reason why this fixed point was established. It is to measure and estimate the location of the ground more accurately, so as to be more accurate in the construction industry, status, and geological exploration.

1. What is the origin of the earth?

2. The magic of the origin of the earthLife says: Don't be limited to what is in front of you, there are poems and distances waiting for you. The same is true of our country.

Break the bottleneck, break through yourself, and establish your own geographical coordinates. In addition to the function of accurate positioning, the origin of the earth also plays a very important role in the construction, national defense, and economic development of the country. With the origin of the earth, in the process of disaster prevention and earthquake relief, you can reduce a lot of resistance, with the origin of the earth, how to build in China's urban development will be very easy to establish their own urban image.

The application of the origin of the earth is very extensive, and it plays a very important role in our national construction and national construction.

The origin of the earth, also known as the geodetic datum point, is the starting point and datum point of the national geographic coordinates - latitude and longitude. Its main role is to play an important role in China's economic construction, national defense construction, and social development. The origin of the earth is open to the outside world, which can be visited and visited, and it is also a good place to carry out popular science knowledge education.

The origin of the earth not only has an important impact on various constructions and science and technology, but also symbolizes the dignity of the country.

As the origin of our country's earth, this can also be based on this origin, and the exploration of our country's geology will make a great contribution to our country's economic and military development.

The origin of the earth in our country can be used to determine other parties more accurately, which plays a great role in military affairs and makes it more convenient for us in daily life.

The role is to be able to know exactly where you are, and it is also helpful to China's economic construction, national defense construction, and social development

It is an artificially defined point by which we can know exactly where our geographical location is.

1.The meaning of the origin of the Chinese earth.

The origin of China's earth refers to the starting point of the geographic coordinate system selected by Chinese geographers, and is also an important basic platform in the fields of geophysics, meteorology, space and other fields in China in recent years, which was determined by the Chinese Geographical Society in 2003 and is a very important national scientific project.

2.The location of the origin of the Chinese land.

The location of the origin of China's land is located in Hongyuan County, Sichuan Basin, because it is located in the westernmost part of the continental plate, and has contact with the Indian plate, so it is also one of the most prone places in China. In this area, the instantaneous displacement of the ground can reach several meters, enough to overturn a building.

3.The importance of the origin of the Chinese earth.

The establishment of China's earth origin is of great significance, which provides a more accurate and unified basic platform for China's geophysics, meteorology, earth science and space technology, opens a new era in China's surveying and mapping technology and geodesy, and provides a solid foundation for China's modernization.

4.The influence of China's geodetic origin on the field of international geography.

The establishment of the origin of China's land has not only brought many benefits to the field of science and technology in China, but also had a positive impact on the field of international geography. The establishment of China's geodetic origin has put China's surveying and mapping technology and geodesy at the forefront of the world, and has made great contributions to the world's geographic science.

5.The unique significance of the origin of the Chinese land.

The establishment of China's origin is a major breakthrough in the field of science and technology in China, which marks the continuous improvement of China's position in the field of science and technology in the world and provides strong support for China's modernization drive. In the future development, the origin of China's land will continue to play its unique significance.
