Covering a total land surface of 149 million square kilometers, this year's dataset is the world's first open-access map of the Earth's land cover with a high resolution of 30 meters, according to the Ministry of Natural Resources.

The datasets, which are released every 10 years, are commonly known as the GlobeLand30. This year's dataset comprises 10 types of land cover, including forests, grasslands, glaciers and wetlands. A total of 966 sub-datasets are included.
