BEIJING — China's first civilian high-definition mapping satellite Ziyuan III 01 has celebrated its 8th birthday in orbit.

Despite its five-year design life, it continues to collect data, the Ministry of Natural Resources said on Jan 15.

Since it was launched in January 2012, the satellite has sent back 3D data covering 79 million square kilometers of the globe as of Dec 31, 2019.

It has enabled China to produce 1:50,000-scale maps, ridding the country's dependence on imports of satellite images, according to the ministry.

The Ziyuan III 01 is tasked with providing data for the country's land-resources investigation, disaster prevention, agriculture development, environmental surveying and urban planning.

The satellite has offered services to more than 40 countries and regions over the past eight years, the ministry said.
