The China National Space Administration announced on Thursday that the Gaofen-7 Earth observation satellite has been put into service, representing significant progress for the country's surveying and mapping capabilities.

Launched on Nov. 3, 2019, Gaofen-7 is China's first civil-use optical transmission 3D surveying and mapping satellite that reaches the sub-meter level.

Equipped with two line-scan cameras and a laser altimeter, the satellite can provide 1:10,000 scale satellite 3D mapping for users in China and countries participating in the Belt and Road Initiative.

During in-orbit tests, satellite functions such as the monitoring of geographical conditions, agricultural surveys, and road constructions have been verified.

In May, using data from the Gaofen-7 and Ziyuan III satellites, scientists drew a 1:10,000 scale topographic map for surveyors to measure the height of Mount Qomolangma.
