Full coverage of land and territory, my country's 1:50000 and smaller scale topographic maps completed

1. my country is accelerating the transformation and upgrading of its surveying, mapping and geographical information undertakings, achieving full coverage of land and territory with 1∶50000 and smaller scale topographic maps.

2. The Ministry of Natural Resources stated that our country has abundant spatial geographical data resources. At present, 1∶50000 and smaller scale topographic maps have achieved full coverage of the land and land, and 1∶500~1∶10000 series scale topographic maps have been achieved Necessary coverage of land territory. A series of spatial geographic databases have been built and updated regularly, accumulating massive data resources.
3. Chen Jun, deputy director of the Department of Land Surveying and Mapping of the Ministry of Natural Resources, said: "Since 2022, a total of approximately 7 million square kilometers of terrain-level, city-level, and component-level real-life 3D models with different levels of precision have been constructed. Basically completed The national satellite navigation and positioning reference station 'One Network' has the ability to provide national unified surveying and mapping reference services for various surveying and mapping activities. "
This site notes that the natural resources system will
4. strengthen the supply of real-life three-dimensional data. , establish a new generation of national surveying and mapping benchmark system, build an integrated spatial geographical data resource system of "above and below ground, land and sea, 2D and 3D", continuously improve coverage, precision, freshness and richness, stimulate application needs, and build a multi-dimensional Digital application scenarios support the development of digital economy, low-altitude economy, autonomous driving and other industries.
