Our first phenology-based cropland mapping algorithm (PCM1) used different thresholds of land surface water index (LSWI) by considering varied crop phenology along different elevations. ...
To decrease the classification errors due to elevational differences in crop phenology, we developed two pixel- and phenology-based algorithms to map croplands using Landsat imagery and the Google Earth ...
LSWI is sensitive to equivalent water thickness attributed to the SWIR band, which is sensitive to leaf water and soil moisture [52] . ...
