Analysis of Remote Sensing Technology Promoting the Development of Spatial Information Industry

: In recent years, the Chinese government, the Institute of Spatial Information Industry and related scholars have paid more and more attention to the application of remote sensing data and the development of related industries. Remote sensing technology is gradually developing to the civilian field and related applications have served the public, and the space information industry has developed rapidly. This is precisely because the development of remote sensing technology promotes national demand and the space information industry also benefits from this. The formation of spatial information industry has systematically analyzed and discussed the relationship between remote sensing technology and spatial information industry, the role of remote sensing technology in promoting the development of spatial information industry, and the development value, current situation and development direction of China 's spatial information industry. It is proved that remote sensing technology has a strong role in promoting the development of spatial information industry.


Introduction
Remote sensing, its research field only includes electromagnetic detection, but the detection that does not directly contact the research phase can be called remote sensing. Space information industry is a strategic emerging industry and high-tech service industry based on remote sensing, satellite communication, navigation and other technologies, which integrates multidisciplinary and multifield integration [1] . The overall level of China 's spatial information industrialization is low, the scale is smaller than that of developed countries, and the leading enterprises with international influence are scarce. The developed remote sensing technology can promote the development of space information industry and make up for its defects. In addition, the remote sensing satellite industry is a national strategic emerging science and technology industry. Accelerating the development of the satellite industry is conducive to promoting the development of the national space information industry and benefiting the development of the national society. It plays a very important role in making China 's aerospace industry firmly in the leading position in global development and enhancing the comprehensive national strength of the country.

Development Status of Remote Sensing Technology
The development trend of remote sensing technology is that remote sensing technology is developing in the direction of quantification, intelligence, trend, application and Internet of things. In the past ten years, it has been widely used in various aspects, and its application will be more and more extensive in the future [2] . In general, the development of remote sensing in China has gone through the initial stage and the experimental stage, and then to the later stage of industrialization. It has made great contributions to basic theory, development platform, sensor localization, system integration, application research, scientific research and talent cultivation, and also promoted the development of remote sensing industry and national economic construction.
(3) Remote sensing technology achievements Due to the airborne remote sensing experiment and application research, especially the new sensor experiment and system integration experiment using the airborne platform, good results have been achieved. China has the ability to independently develop remote sensing sensors and realize the localization of sensors. China has been able to independently develop common photographic types, scanning types, radar imaging types and non-image type remote sensing sensors, and has realized the localization of sensors.
As of September 2020, there are 824 remote sensing satellites in orbit around the world, with 182 in China, ranking second. It includes satellite resource series satellites for detecting and studying earth resources, environment series satellites of earth observation system for environment and disaster monitoring, and remote sensing satellites such as high-resolution series of autonomous controllable satellites for establishing a set of high time resolution, high spatial resolution and high spectral resolution.
At present, China has built five satellite receiving stations, which are located in Miyun, Kunming, Sanya, Kashgar and Antarctica. It can provide a considerable amount of data and related services for China 's scientific research, disaster monitoring, environmental testing, agricultural production and other aspects. At the same time, it is also the largest civil receiving station in the world to receive and process data. And it covers most of Asia, providing a data base for the development of China 's remote sensing industry.
In the future, the development of remote sensing in China must also strengthen investment, strengthen basic research and new sensor research, continue to strengthen mutual penetration with adjacent disciplines, jointly promote the development of ' digital earth ', and constantly innovate to achieve remote sensing. The leap of the cause serves the sustainable development of human beings, social progress and the improvement of human quality of life.

Therefore, the spatial information industry has also stepped onto the international stage, becoming an effective means for countries to improve their comprehensive national strength and international competitiveness.
With the development of the spatial information industry, remote sensing applications are becoming increasingly diverse, popular, and universal, and are moving towards an international trend of industrialization and commercialization. The field of satellite navigation is also showing vigorous vitality, and GPS is not leading the world at this stage. But a variety of navigation satellites are springing up like mushrooms, and the era of GNSS has arrived.
With the continuous development of 3S technology, the continuous expansion of the scale of spatial information system applications, and the rapid formation of the popularization and industrialization of spatial information systems. The spatial information industry developed through the integration of 3S technologies can maintain a high rate of sustained growth.
In the future, with the establishment of a PNT (positioning, navigation, and timing) service system with satellite navigation as the main application, and the advent of the era of integrating spatial information technology with information carriers such as mobile communications and the Internet, the spatial information industry will inevitably enter a new stage of development in which Space-Earth Integration, services are ubiquitous, and information intelligence is realized.

Different from the traditional high-tech industrial base construction ideas and construction mode, the ultimate goal of space information industry base construction is to achieve higher commercial value of data value-added services. Therefore, the basic conditions of the space information industry base not only need the traditional infrastructure such as office facilities, but also need the professional infrastructure such as remote sensing satellites. It requires not only professional basic data from remote sensing satellites, aircraft and other platforms, but also comprehensive and professional government basic data from local provinces, cities, counties, township governments and industries.
