Using space technology such as synthetic aperture radar (SAR) remote sensing to analyse radar waves emitted from surveillance satellites makes it possible to assess the state of the world's forests with an accuracy that is close to real-time.
利用合成孔径雷达遥感等空间技术可分析从监视卫星上发射出的雷达波，从而可以对全世界的森林状况做出近乎实时的准确评估。
