Best index slope extraction
Reduces noise in NDVI time-series.
An object of class ‘NDVI’ containing raw NDVI values.
Sliding Period of the BISE-algorithm, default value is 40.
Knowledge regarding the phenological cycle in temperate climates and its temporal evolution is used to detect and eliminate cloud contaminated observations. As the algorithm is searching forward within daily NDVI observations over 1 year, decreases are only accepted if no higher value is found within a so called sliding period. A period of 40 days proved best for our study area but might have to be modified when study areas in different climates are investigated.
An object of class ‘NDVI’ containing raw and corrected NDVI values.
