Given a shapefile of sampling boxes, and a path to a directory of 4-band ortho-imagery prints rgb and/or ndvi plots of the sampling area with numbered boxes superimposed. While the function prints both rgb and ndvi by default, the user can turn either off by setting either the rgb or ndvi arguments to FALSE.

plot_samples(in_path, out_path, samples = samples, print_rgb = TRUE,
  print_ndvi = TRUE)

Arguments

in_path

is a character vector containing the path to the orthoimagery

out_path

is a character vector specifying the output directory for the plots

samples

is a SpatialPolygonsDataFrame object (the sample boxes shapefile)

rgb

is a logical indicator, prints rgb plots if true

ndvi

is a logical indicator, prints ndvi plots if true

Value

prints an rgb and/or ndvi plot into the out_path directory
