High score+Beidou, the prospect is available

On July 12, a heavy rain hit Beijing, and the meteorological department had issued a warning one day in advance. Not long ago, the weather forecast also provided accurate information for the celebration of the 100th anniversary of the founding of the Communist Party.

At the recent seminar on the development of the digital earth industry, Sun Jian, president of the China Meteorological Service Association, said that with the development of meteorological technology, the Chinese public's satisfaction with meteorological services has reached a peak of 92%, which is almost close to the "ceiling". Difficult to go further. But he also pointed out that in the meteorological service industry, the digital earth has great potential. "For example, the combination of high scores and Beidou is very likely to bring revolutionary changes to weather forecasting."

Wu Yirong, academician of the Chinese Academy of Sciences and president of the Institute of Aerospace Information Innovation of the Chinese Academy of Sciences, also said that the future development of aerospace information will have many applications.

Aerospace information continues to explode

Statistics show that my country has more than 300 satellites in orbit, ranking second in the world after the United States. Moreover, with the advancement of technology, the resolution of satellites has been continuously improved, and more and more images have reached the sub-meter level.

Wu Yirong couldn't help but sigh: "We, the Earth observation people, never thought that China could have so much space-to-earth observation data, and the resolution could be so high. With space and space big data, it will undoubtedly bring benefits to many applications. It is possible." He said that with the continuous development of aerospace information, digital earth is the last link of aerospace information, and it is also the link with the most market value.

Digital Earth was first proposed by the United States in 1998. It uses remote sensing satellites, navigation satellites, aerial photography and other earth observation means, digital technology, geographic information technology, etc. to build a digital, visualized, networked, and intelligent global information model. Shao Zongyou, vice chairman of Zhongke Xingtu, pointed out that although a large number of industries such as natural resources, transportation, emergency response, and agriculture all require aerospace big data, the satellite support obtained is far from enough. The reason is that there are too many, too professional and complex data acquisition links, making the ground industry at a loss.

To this end, with the support of the Institute of Aerospace Information Innovation of the Chinese Academy of Sciences, Zhongke Xingtu has made a series of technological breakthroughs and developed a "one-stop office platform" - GEOVIS Digital Earth - using a software to capture, decode, All intermediate links such as modeling and application are encapsulated, so that ground applications only need to deal with digital earth software.

It sounds simple, but the more encapsulation links are involved, the more difficult it is to develop. Shao Zongyou pointed out that the digital earth itself has a high threshold and needs to apply a new generation of information technologies such as high-performance computing, artificial intelligence, cloud computing, big data, and even virtual reality.

For example, in the past, the application of earth observation data was mainly through manual identification, but now it is difficult to meet the demand due to the huge amount of data. It has been converted into human-machine collaboration and intelligent extraction, which greatly reduces the workload of human beings. Wu Yirong believes that this is not enough. "In the future, we can do manual training in the background on a regular basis, and the front desk will be fully automated by machines."

"Aerospace information is an important direction for the development of information technology. For those of us who are engaged in aerospace information technology, we hope that it will become the only direction. In the future, all information will go to the sky. For example, submarine cables may be used by the Aerospace Information Network in the future. Instead." Wu Yirong said with a smile.

High score + Beidou prospects are promising

Shao Zongyou proposed that the high-resolution constellation and the Beidou constellation should be integrated to jointly provide high-precision spatial information services for the country's key infrastructure. In fact, there are similar plans in the world. For example, the United States proposed GPS+EOS very early, Europe proposed Galileo+Copernicus, and Russia has plans to integrate the GLONASS system with resource satellites.

The rapid development of China's aerospace industry has greatly improved the self-supply rate of my country's ground imagery, and the quality has also caught up with the highest level abroad, providing an independent and controllable data source for the construction of the digital earth.

"The ideas and routes of Gaofen + Beidou are also advanced in the world." Shao Zongyou said that the combination of the two will provide many issues that were difficult to solve with a single method in the past. For example, build a more refined smart city spatiotemporal big data management and control platform, refine buildings, components, facilities, etc. to the centimeter level, including three-dimensional display of natural landforms and underground pipe networks; more accurate emergency prevention and control of meteorological and geological disasters ; even accurate emissions assessments for carbon neutrality and more.

"I believe that after the new generation of digital earth integrates the two systems of Gaofen and Beidou, it will surely provide more powerful data acquisition, processing and carrying capacity for my country's ground application industry." Shao Zongyou said. Source: Chinese Science Journal
