China Builds High Resolution Rice Maps, Using SAR

0

Scientists from China have now developed high resolution maps with crucial information, by using cloud-free Synthetic Aperture Radar images from Sentinel-1 satellite, the Random Forest classifier, and the Google Earth Engine cloud computing platform. The Sentinel-1 satellite was launched by European Space Agency and its data is available for free.

“We mapped rice growing areas accurately in India and Bangladesh using microwave satellite images. The knowledge of spatial extent and rice cropping intensity is an asset to the government and other agencies for efficient land and water resources management along with environment sustainable growth to ensure food security for all the people in the world,” said Dr Mrinal Singha of Chinese Academy of Sciences, Beijing.
