A novel approach to detect the spring corn phenology using layered strategy
International Journal of Applied Earth Observation and Geoinformation(2023)
摘要
•We proposed a layered strategy to detect crop phenology on a regional scale.•We presented a novel Phenology Separability Index (PSI).•We analyzed the separability of different features in each phenological stage.•Meteorological factors are better for detecting phenological stages.
