...multi-sensor remote sensing data via a algorithm. Some progress has been made in automated land cover classification techniques such as an unsupervised algorithm called independent component analysis =-=[45]-=- and a modified subspace classification method [46]. The advantage of automated algorithm is to avoid time-consuming and laborious manual interpretation and processing. A rule-based decision tree clas...

Recently, some efforts were made to extract sub-pixel landscovers with crop phenology from MODIS time series =-=[23,24]-=-, the so-called phenological mixturesanalysis (PMA). Both methods share the same principle, i.e., the SMA approaches improve the spatialsresolutions with spectral signature of crops, while the PMA app...
