原始语种摘要: Rice (Oryza sativa L.) is the primary staple food source for more than half of the world’s population and has a profound influence on the livelihood of farmers. Lowland rice in tropical and subtropical regions can be detected precisely and its crop growth can be tracked effectively through Synthetic Aperture Radar (SAR) imagery, especially where cloud cover restricts the use of optical imagery. The SAR time-series data has been processed by fully automated processing chain in MAPscape-Rice software was used to convert the multi-temporal SAR data into terrain-geocoded σ° values, underwent a series of basic processing steps to generate terrain-geocoded σ° values suitable for analysis. Then the multi-temporal stack was analyzed using a rule-based classifier to detect rice areas. The DNDC...
