Statistical Estimation of Phenological Parameters
Description
Provides functions and methods for estimating phenological dates (green up,
start of a season, maturity, senescence, end of a season and dormancy) from (nearly)
periodic Earth Observation time series. These dates are critical points of some
derivatives of an idealized curve which, in turn, is obtained through a functional principal
component analysis-based regression model. Some of the methods implemented here are
based on T. Krivobokova, P. Serra and F. Rosales (2022) .
Methods for handling and plotting Earth observation time series are also provided.
