The Ministry of Natural Resources has just announced the release of China's pioneering set of geometric reference imagery, encompassing the entire landmass with a resolution surpassing 0.5 meters. This milestone achievement establishes a standardized 'spatial yardstick' for the production of remote sensing imagery across the nation. This reference imagery serves as a universal calibration tool for diverse satellite images, significantly refining the accuracy of data pertaining to housing areas, roads, and other features. It effectively addresses the precision control dilemmas encountered in intricate regions, elevating the overall positioning precision of nationwide remote sensing imagery by more than twofold. Moreover, it resolves the longstanding issue of inconsistent imagery references that have impeded industrial progress.

Looking ahead, this reference imagery is poised for extensive utilization in endeavors such as the construction of a 3D real-scene representation of China. Furthermore, it will be made openly accessible to the public, with the anticipation of slashing production and processing expenses for remote sensing imagery across multiple sectors. This move is expected to catalyze the growth of the satellite remote sensing application industry.
