Inheriting the spirit of dedication and measuring thousands of mountains and rivers
[Practice the spirit of the general secretary's reply letter and deeply implement the strategy of strengthening the country with talents in the new era]
In 2020, my country's Mount Everest elevation measurement has attracted worldwide attention. This is another great feat after my country first placed the measurement target on the top of the earth in 1975 and completed the second accurate measurement in 2005.
In May 2015, Shao Shikun and other 6 veteran team members and party members who participated in the first Everest altimetry mission (the former first geodetic survey team of the National Bureau of Surveying, Mapping and Geographic Information, now the first geodetic survey team of the Ministry of Natural Resources) gave the General Secretary Xi Jinping wrote a letter to report the glorious history of the National Test Team and the struggles of the younger generation.
On July 1 of the same year, General Secretary Xi Jinping replied to the 6 old members and old party members of the National Survey Team, fully affirming the touching deeds and lofty spirit of the National Survey Team for serving the country and climbing the peak. members expressed fervent hope.
Surveying and mapping is the pioneer and basic guarantee for the country's economic and social development and national defense construction. Only with a solid "foundation" can "high-rise buildings" in all walks of life be built. For decades, generations of surveying and mapping workers have been brave pioneers, traversing mountains and seas, traveling through the sky and latitudes, and interpreting the surveying and mapping spirit of "love the motherland, loyalty to the cause, hard work, and selfless dedication" with sweat and even life.
The spirit of bravely climbing the peak is passed on from generation to generation
"The general secretary's reply has brought great encouragement to all surveying and mapping workers. Every year when new team members enter the unit, they will learn this reply and the team's history, and pass on the spirit of dedication to the country from the older generation." Li Guopeng, the captain of the brigade, said.
Today, Shao Shikun, Xue Zhang, Liang Baogen, Zhang Zhilin, Yu Qiqing, and Lu Furen, who wrote letters to General Secretary Xi Jinping, are all in their old age.
Although they are old, they still care about the cause of the party and the people, setting an example for the younger generation of surveying and mapping workers.
"The older generation of surveying and mapping people devoted themselves to their careers, and even gave their lives. This kind of professionalism is very worth learning." said Chen Jingtao, technical director of the new technology application department of the national survey team, "I came to the national survey team in July 2015. Yes, just in time for the general secretary to reply to us, which has injected a strong impetus into my future work."
In the past 7 years, Chen Jingtao has grown from a rookie in surveying and mapping to the technical backbone of the team.
In the 2020 Mount Everest elevation measurement mission, he participated in the preliminary research and development, testing, and debugging of equipment such as ice and snow detection radar, GNSS receivers, and summit targets. Equipment training is carried out for each climber.
"From Lhasa at 3,600 meters above sea level, to Dingri County at 4,300 meters, and then to Mount Everest Base Camp at 5,200 meters, although everyone had strong altitude sickness, they rushed into preparations after a short rest." Chen Jingtao said , the team worked non-stop to ensure that the radar software and hardware, targets and other equipment fully met the requirements of Mount Everest peak measurement.
"This summit measurement can be described as twists and turns. At the most difficult moment, we held two themed party day activities at the base camp. Everyone fully discussed the difficulties they faced, and they were determined to complete the task with the determination to win." Li Guopeng introduced that in the end, they withstood the pressure, overcame difficulties, successfully completed the measurement task, and created a number of "firsts": the first time to fully apply my country's Beidou satellite navigation system in the elevation measurement of Mount Everest; the first time to achieve Mount Everest The peak top measuring instruments and equipment were fully localized; the first gravity measurement was carried out on the top of Mount Everest...
Li Guopeng said: "From the older generation of players who wrote letters to the general secretary to this new group of players, in the past few decades, the technical equipment in the team has achieved major breakthroughs and major changes, but the team has shown great achievements in the face of major national tasks. The spirit of being willing to give and to climb the peak has not changed.”
Achieving ideal aspirations in the heavy duty of participation
In June, summer has arrived, but the night in Yajiang County, Sichuan Province is still a little cool.
Li Zhenhong, Dean of the School of Geological Engineering and Surveying and Mapping of Chang'an University, led the team back to the station to end the day's inspection.
They are conducting research on the Qinghai-Tibet Plateau traffic project here.
"The general secretary's reply expresses his concern and affirmation for the entire field of surveying and mapping, and encourages surveying and mapping workers to continue to move forward." Li Zhenhong said that he had stayed in the UK for 19 years and returned to Chang'an University in 2019.
"I am fortunate to catch up with the new era of vigorous development and realize my ideals and aspirations by participating in the century-old strategic project implemented by the country." He said.
The Qinghai-Tibet Plateau transportation engineering project has been in progress for more than two years. In order to effectively identify surface disasters such as giant landslides, remote debris flows, and ice lake bursts along the project, Li Zhenhong led the team to innovatively design a major geological disaster "sky-sky-ground-body" The multi-source three-dimensional collaborative monitoring network system can grasp the surface data in time, and take targeted prevention and control measures to ensure the safety and reliability of traffic engineering.
With the development of the times, the surveying and mapping technology is also constantly improving and innovating.
In August 2016, the National Survey Team established a new technology application department to optimize, innovate and demonstrate application of high-tech equipment such as aviation gravimeters and multi-beam sounding systems.
There are many kinds of water resources such as rivers, lakes and reservoirs in my country, and the surrounding environment is complex and diverse.
In order to fill the gap in the census of inland water resources, Liu Shengzhen, head of the New Technology Application Department, led a team to establish an integrated above-water and underwater surveying and mapping technology system for different water environments by using a variety of platforms and sensors.
They successfully developed a post-processing method for integrated navigation in multi-beam surveying operations, which greatly improved the operational efficiency of surveying and mapping complex waters in mountainous areas.
"This is a measure of our water resources, and it is also an indispensable step in the construction of underwater projects, such as building bridges and piers." Liu Shengzhen said.
Yao Yibin, Dean of the School of Surveying and Mapping of Wuhan University, introduced that today’s surveying and mapping majors have entered the development stage of informatization and intelligent surveying and mapping integrating a new generation of information technologies such as aerospace technology and intelligent technology. In response to major national strategic needs such as remote sensing, three research centers for intelligent surveying and mapping, intelligent navigation and intelligent monitoring have been planned and deployed, and a large number of internationally leading scientific research results have been achieved.
Give full play to the advantages of surveying and mapping to serve the national strategy
The development and growth of my country's surveying and mapping industry is inseparable from the persistence and dedication of generations of surveying and mapping personnel.
"'Remain true to our original aspirations, we will always be the best.' We always keep in mind the general secretary's entrustment. In terms of talent training, we take Lide and cultivate people as the fundamental goal, and constantly innovate the concept of talent training." Yao Yibin said that the School of Surveying and Mapping of Wuhan University has added artificial intelligence, Courses such as big data are deeply integrated with the knowledge, ability and quality requirements of surveying and mapping majors, and the exploration and practice of new engineering reforms for surveying and mapping majors in the intelligent era will be carried out, and efforts will be made to cultivate spatiotemporal information technology talents who can lead the future.
Li Zhenhong also introduced that based on the academic frontier of geological hazard prevention and control, it is the characteristic and advantage of the School of Geological Engineering and Surveying and Mapping of Chang'an University to give full play to the advantages of surveying and mapping to serve the national strategic needs.
To this end, the college has created a collaborative integration model of science and education, emphasizing interdisciplinary in professional education, and cooperating with communication, computer and other majors to offer courses such as geological engineering and modern surveying and mapping; In specific case studies such as the Tonga volcanic eruption and the Qinghai Menyuan earthquake, students are encouraged to grow rapidly.
Traveling thousands of miles a day, measuring the earth, surveyors are always on the road.
Many honorary titles such as the "Heroes Brigade" won by the first team of the National Test Team have been exchanged for more than 60 years by generations of players with sweat and even their lives.
Li Guopeng said: "We work in the field for 8 to 10 months a year. The first team of the National Test Team first cultivates the combat ability and hard-working spirit of the players to go deep into the field and take root in the front line, and then give full play to the strengths and advantages of the players to form talents. The echelon and innovation team will eventually create a national first-class basic surveying and mapping team with excellent work style, first-class technology and advanced equipment to meet the needs of future national construction."
