the development of surveying and mapping geographic information technology in henan province is inseparable from a series of policy measures and technological innovations. in 2023, henan province issued the "overall implementation plan for the construction of realistic 3d henan (2023-2025)", which clearly proposed to achieve terrain-level real-scene 3d coverage of the entire province by 2025. today, the province has built 142,000 square kilometers of 3d geographical scenes, and the mountains and rivers of the central plains are real and three-dimensional and within reach. all this is inseparable from the support of satellite data, which is completed by the precise positioning and deployment of the "henan no. 1" satellite.
the "henan no. 1" satellite is the first independently developed national satellite launched by henan province in 2022. its high-altitude perspective captures every car on the ground, providing strong technical support for dynamic remote sensing monitoring. in 2023, henan province will take the lead in realizing the nationalization of the basic information platform for land and space, and build the basic information platform for land and space in henan province and the "one map" implementation supervision information system for spatial planning. this not only provides users with convenient data acquisition and application opportunities, but also greatly improves data management and utilization efficiency.
the breakthroughs made by henan province in the field of surveying and mapping geographic information technology have not only brought important opportunities for its own economic and social development, but also provided valuable experience and reference for other provinces. as the first province in the country to achieve industrial substitution of the basic information platform for land and space, henan province's successful experience has provided a reference for other provinces and opened up new possibilities for promoting the application of surveying and mapping geographic information technology in various fields of society. in the future, henan province will continue to increase investment and research in surveying and mapping geographic information technology, continuously optimize the technical system, and contribute to the realization of high-quality economic and social development.
