Global climate change has taken us more efforts in monitoring the eco-environment. To support the government decision making, we provide dynamic theme series of remote sensing monitoring services, including desertification, forest and wetlands coverage, nationwide water loss and soil erosion, etc.

Desertification Monitoring




China has been suffering serious desertification. The direct economic loss caused by the desertification reaches billions RMB per year and other indirect losses with respect of ecological damages are hard to be evaluated. The satellite remote sensing monitoring is the most important technical method to manage and contain the process.

21AT has continuously utilized the Beijing-1 small remote sensing satellite to intensively monitor the land desertification in China for 6 consecutive years. The analytical results have helped the government to understand the real situation of the desertification in national scale and provided the scientific evidences and technical supports for them to come up with policies and measures for desertification control and management.

Forest Resources Monitoring


Dynamic satellite monitoring is indispensible in nationwide forest resource management and development.

Using the Beijing-1 small remote sensing satellite, 21AT fulfilled the needs of frequent monitoring and survey of the annual changes of the forest resources for national forestry agencies.
