Vegetation Phenological Cycle and Anomaly Detection using Remote Sensing Data R package npphen version 2.0.1 CRAN Task View: AnomalyDetection (https://CRAN.R-project.org/view=AnomalyDetection) Calculates phenological cycle and anomalies using a non-parametric approach applied to time series of vegetation indices derived from remote sensing data or field measurements. The package implements basic and high-level functions for manipulating vector data (numerical series) and raster data (satellite derived products). Processing of very large raster files is supported.
