Abstract

The invention proposes a monitoring method for regional actual irrigation area based on optical and radar remote sensing data, which combines the short-wave infrared index sensitive to changes in soil and vegetation moisture content and the change of radar backscatter coefficient, and based on satellite remote sensing data, can monitor regional irrigation. Activities are dynamically detected to achieve accurate extraction of irrigated areas.
