China boasts a total of 7.566 million square kilometers of vegetation cover, while buildings cover 153,000 sq km of land, the State Council Information Office unveiled at a press briefing last Monday.
The numbers are part of the results of China's first national geoinformation survey, which collects basic information about the country's natural resources, such as their location, range and area.
The survey started in January 2013 and lasted more than three years, with the help of 50,000 people and technologies such as remote sensing satellites, drones and 3D laser scanning.
The surveyors combined aerial photography and on-site verification in order to provide more precise information and improve the survey's quality, said Li Weisen, deputy director of the National Administration of Survey, Mapping and Geoinformation, which led the work.
According to officials and experts, the survey relates closely to people's daily lives.
The results of the survey will be made available to public departments, to enable them provide better public services.
