f2a.map.jpeg: f2a.map.jpeg

Description

Creates a time series of jpegs. One jpeg is created for each year of the map output of f2a.raster.

Usage

f2a.map.jpeg(years, folder, OUTPUT.fn, height = 10, 
width = 10 * (dim(mapgrid.dist)[2] / dim(mapgrid.dist)[1]), 
units = "in", res = 400)

Arguments

years

Vector of the years included in the time series data.

folder

Folder (full path) containing the input rasters. This is also the folder where the output will be written.

OUTPUT.fn

Filename of output from f2a.raster.

height

The height of the device.

width

The width of the device. The default is the width that will give accurate ratio of height to width for a raster.

units

The units in which height and width are given, which can be px (pixels, the default), in (inches), cm or mm.

res

The nominal resolution in ppi which will be recorded in the bitmap file, if a positive integer. Also used for units other than the default. If not specified, taken as 300 ppi to set the size of text and line widths.

Value

Returns nothing

Details

Creates one jpeg for each year in years.

Examples

Run this code

# define years
	years <- c(1984, 1986:2010)
	
	# define a folder for all outputs
	folder.in <- paste(system.file(package = "ShapeSelectForest"), 
	"extdata", "helpexamples", sep = "/")
	folder.out <- getwd()

	# define filenames
	flat.pred.fn <- "MINI_FLATPRED.img"
	b5.fn <- "MINI_B5.img"
	fi.fn <- "MINI_FI.img"
	nbr.fn <- "MINI_NBR.img"
	ndvi.fn <- "MINI_NDVI.img"
	INPUT.bands <- c(b5.fn, fi.fn, nbr.fn, ndvi.fn)

	# call f2a.raster
	ans1 <- f2a.raster(years = years, folder.in = folder.in, folder.out = folder.out, 
	OUTPUT.fn <- "f2a_example.img", flat.pred.fn = flat.pred.fn, INPUT.bands = INPUT.bands)

	# create jpegs 
	ans2 <- f2a.map.jpeg(years = years, folder = folder.out, OUTPUT.fn = "f2a_example.img")
