BEIJING, June 19 (Xinhua) -- The latest construction of a remote sensing monitoring database of China's land-use at a 1:100,000 scale has been completed.

Based on the land-use data of 2010, the 2015 national land-use database of China was based on satellite images of Landsat and HJ-1A, according to the website of Aerospace Information Research Institute of the Chinese Academy of Sciences.
