The important goal of jointly building the "Silk Road Economic Belt" and the "21st Century Maritime Silk Road" is to achieve policy communication, facility connectivity, smooth trade, financial and people-to-people communication with countries along the route. The "Belt and Road" strategy involves many countries and has a vast territory. The development levels of countries vary greatly. The information resources in economic construction, social development, resource development and utilization are not rich enough. It is urgent to strengthen information interconnection. Spatial information has the characteristics of wide coverage and strong timeliness, and can provide information support services for infrastructure construction, energy resource development and utilization, environmental disaster monitoring and evaluation, etc. To jointly build a spatial information corridor and further improve the spatial infrastructure will play an important role in the implementation of the "Belt and Road" strategy.

The spatial information corridor is a comprehensive project to carry out spatial information services for the implementation of the "Belt and Road" strategy under the service model of "Internet Space Information" with the purpose of realizing comprehensive integrated application services of space information. The project makes full use of the existing and planned space-based and ground facilities resources in my country, with space-based infrastructure such as satellite communications, remote sensing, navigation as the main body, and focusing on the interconnection of ground networks and facilities, supporting the comprehensive application of space information in key areas such as energy resource development, environmental disaster reduction, infrastructure construction and emergency safety in countries along the "Belt and Road", and provides a world-wide integration, win-win cooperation, safe and reliable information channel for the interconnection of resource information, cultural dissemination information, public welfare and safety information, etc.

The application fields of the spatial information corridor in the "Belt and Road" are mainly reflected in the following four aspects: First, it can provide spatial information interconnection for the planning, design and implementation of infrastructure construction such as railways, highways, ports; Second, it can provide spatial information support services for resource and environmental surveys and monitoring such as agriculture, forestry, water conservancy; Third, it can provide spatial information guarantee for monitoring and evaluation of natural disasters such as earthquakes, floods, and fires; Fourth, it can provide spatial information emergency services for maritime search and rescue, navigation safety monitoring, etc.

my country has basically built a relatively complete aerospace science and technology industrial system. In the future, it will further build and improve national space infrastructure with reasonable layout, global coverage, and significantly enhance international service capabilities, which can provide spatial information support and service guarantees for the implementation of the "Belt and Road" strategy.

my country has established a good cooperation mechanism with countries along the "Belt and Road" route, laying a good foundation for the application and promotion of spatial information technology. Countries along the "Belt and Road" have also developed and launched several communication or remote sensing satellites, established corresponding ground and application systems, and have a good foundation for cooperation in aerospace technology and application. These aerospace technologies and cooperation have laid a good foundation for jointly building a space information corridor. The space information corridor will make full use of the existing and planned world resources of my country and countries along the "Belt and Road", jointly establish a space information sharing and service platform, take major engineering projects as a starting point, jointly carry out typical application demonstrations, and build a three-dimensional space information system with "sensation, transmission, knowledge and use", to provide space information guarantee for Chinese enterprises to "go global", and use international promotion and application of space information as a driving force to drive the international development of my country's aerospace equipment and high-tech industries, further enhance my country's international influence, and promote spatial information to better serve the economic construction and social development of countries along the "Belt and Road".

The spatial information corridor will focus on building a spatial communication information system and improve the interconnection capabilities of spatial information. First, strengthen cooperation in space-based resources, jointly build satellite communications and data acquisition systems, and realize the interconnection of space-based information networks; second, strengthen cooperation in ground-based resources, jointly build several communication satellite telecommunications ports with countries along the "Belt and Road" to achieve interconnection of ground information networks; third, strengthen cooperation in communication services, explore the establishment of a joint operation mechanism for communication satellites, realize safe, reliable, efficient and convenient information interconnection in the "Belt and Road" region, and support the regional economic construction and social development of the "Belt and Road".

The spatial information corridor will focus on building a remote sensing sharing service platform to improve the remote sensing information sharing service capabilities. Coordinate the use of existing remote sensing satellite resources in countries along the Belt and Road, jointly develop multi-task small satellite constellations composed of hyperspectral small satellites, micro-nano satellite constellations, etc., build corresponding ground data reception, processing and distribution systems, build a remote sensing satellite sharing service network, carry out typical application demonstrations, provide comprehensive and timely space remote sensing information sharing services for countries along the Belt and Road, promote the development of space information technology and applications, and promote the common development of countries along the Belt and Road.

The spatial information corridor will focus on building an emergency service guarantee system to improve emergency response service capabilities. Learn from the International Disaster Reduction Charter Mechanism, jointly build the "Belt and Road" spatial information emergency response technical support center, establish a coordinated working mechanism such as "Belt and Road" spatial information emergency response, comprehensive monitoring and joint command, make full use of existing and under-construction resources, build a rapid response information service system such as emergency space information sharing, maritime search and rescue, and emergency rescue, and improve the spatial information emergency response service capabilities of countries along the "Belt and Road".

The Space Information Corridor will focus on strengthening cooperation in the application of space technology and promoting the development of the space information industry. Give full play to the advantageous resources of countries along the "Belt and Road" in technology research and development, product development, industrial promotion, etc., use advanced information technology means such as big data and cloud services, jointly build the "Belt and Road" space technology application cloud service center and regional education and training service platform, build a distributed, online and offline space information technology and application training network, support the establishment of a space information service industry alliance, create several international space information industrial parks, and drive the development of the "Belt and Road" regional space information service industry.

Give full play to the unique advantages of spatial information technology, take the implementation of the "Belt and Road" strategy as an opportunity to jointly build a spatial information corridor, build a spatial information sharing service platform, improve the spatial information service capabilities of the "Belt and Road" road, promote the development of the regional spatial information industry, and help the implementation of the "Belt and Road" strategy to achieve win-win cooperation and common development.
