cleanBrick: Clean the history period of a raster time series

In loicdtx/bfastSpatial: Utilities to monitor for change on satellite image time-series

Description

Filter a time series RasterBrick or RasterStack using a static or statistical threshold in a defined historical period

Usage

cleanBrick(x, monperiod, thresh, dates = NULL, is.max = FALSE, ...)

Arguments

x	RasterBrick or RasterStack. Raster time series to be cleaned
monperiod	Numeric. Beginning of intended monitoring period in bfmSpatial in the form c(year, Julian day). The filter will only be applied before this period (ie. to the history period). If set to NULL, the filter will be applied to the entire time series.
thresh	Either a Numeric static threshold or "IQR" to calcalate the threshold per pixel based on the interquartile zone.
dates	Date. Vector of dates corresponding exactly to layers in x. If NULL, dates are either extracted from sceneID or names(x) using getSceneinfo.
is.max	Logical. Is thresh to be treated as a maximum threshold (ie. all values higher will be removed)? If FALSE, all values lower than thresh will be removed (default).
...	Additional parameters to pass to mc.calc
sceneID	Character. Vector of Landsat sceneID's

Details

If dates is not supplied, these will be extracted from sceneID's, with only support for Landsat at this time. If data come from another sensor, be sure to supply a dates vector.

Value

RasterBrick with values removed according to thresh.
