flat2parameter: flat2parameter

In ShapeSelectForest: Shape Selection for Landsat Time Series of Forest Dynamics

flat2parameter

Description

Based on the disturbance type and the shapes of the four remote sensing bands, a vector of averaged parameters is produced. Which bands are included in the average depends on both the predicted disturbance type and the shapes of the four bands.

Usage

flat2parameter(years, all.shapes, all.durs, all.dyrs, all.mags, mtbs, flat.pred)

Arguments

years	Vector of the years included in the time series data.
all.shapes	Vector (length 4) of the shapes of the four remote sensing bands. Shape values range from 1 to 7.
all.durs	Vector (length 4) of the duration of each shape.
all.dyrs	Vector (length 4) of the year of each shape.
all.mags	Vector (length 4) of the magnitude of each shape.
mtbs	MTBS.
flat.pred	Predicted disturbance Agent. Agent values range from 0 to 6.

Details

flat2parameter can be used on either a single pixel or on a single data point in a data frame.

Value

Returns a vector of length 4 containing the average disturbance year, the duration, the magnitude, and the predicted type.

Examples

	# define years
	years <- c(2001:2010)

	# define parameters
	all.shapes <- c(1, 4, 5, 3)
	all.dyrs <- c(2001, 0, 2004, 2004)
	all.durs <- c(1, 0, 3, 5)
	all.mags <- c(100, 0, 1000, 1500)
	flat.pred <- 5

	# call flat2parameter
	ans <- flat2parameter(years = years, all.shapes = all.shapes, all.durs = all.durs,
	all.dyrs = all.dyrs, all.mags = all.mags, mtbs = mtbs, flat.pred = flat.pred)
