plot.uncertainty_cube: Plot uncertainty cubes

In sits: Satellite Image Time Series Analysis for Earth Observation Data Cubes

Plot uncertainty cubes

Description

plots a probability cube using stars

Usage

## S3 method for class 'uncertainty_cube'
plot(
  x,
  ...,
  tile = x[["tile"]][[1]],
  palette = "RdYlGn",
  style = "cont",
  rev = TRUE,
  n_colors = 10,
  scale = 0.8
)

Arguments

x	Object of class "probs_image".
...	Further specifications for plot.
tile	Tiles to be plotted.
palette	An RColorBrewer palette
style	Method to process the color scale ("cont", "order", "quantile", "fisher", "jenks", "log10")
rev	Reverse the color order in the palette?
n_colors	Number of colors to be shown
scale	Scale to plot map (0.4 to 1.0)

Value

A plot object produced by the stars package with a map showing the uncertainty associated to each classified pixel.

Examples

if (sits_run_examples()) {
    # create a random forest model
    rfor_model <- sits_train(samples_modis_ndvi, sits_rfor())
    # create a data cube from local files
    data_dir <- system.file("extdata/raster/mod13q1", package = "sits")
    cube <- sits_cube(
        source = "BDC",
        collection = "MOD13Q1-6",
        data_dir = data_dir
    )
    # classify a data cube
    probs_cube <- sits_classify(
        data = cube, ml_model = rfor_model, output_dir = tempdir()
    )
    # calculate uncertainty
    uncert_cube <- sits_uncertainty(probs_cube, output_dir = tempdir())
    # plot the resulting uncertainty cube
    plot(uncert_cube)
}
