plot.dem_cube: Plot DEM cubes

In e-sensing/sits: Satellite Image Time Series Analysis for Earth Observation Data Cubes

Plot DEM cubes

Description

Plot RGB raster cube

Usage

## S3 method for class 'dem_cube'
plot(
  x,
  ...,
  band = "ELEVATION",
  tile = x[["tile"]][[1]],
  roi = NULL,
  palette = "Spectral",
  rev = TRUE,
  scale = 1,
  max_cog_size = 1024,
  legend_position = "inside"
)

Arguments

x	Object of class "dem_cube".
...	Further specifications for plot.
band	Band for plotting grey images.
tile	Tile to be plotted.
roi	Spatial extent to plot in WGS 84 - named vector with either (lon_min, lon_max, lat_min, lat_max) or (xmin, xmax, ymin, ymax)
palette	An RColorBrewer palette
rev	Reverse the color order in the palette?
scale	Scale to plot map (0.4 to 1.0)
max_cog_size	Maximum size of COG overviews (lines or columns)
legend_position	Where to place the legend (default = "inside")

Value

A plot object with a DEM cube or a B/W image on a color scale

Note

Use scale parameter for general output control.

The following optional parameters are available to allow for detailed control over the plot output:

• graticules_labels_size: size of coordinates labels (default = 0.7)

• legend_title_size: relative size of legend title (default = 0.7)

• legend_text_size: relative size of legend text (default = 0.7)

• legend_bg_color: color of legend background (default = "white")

• legend_bg_alpha: legend opacity (default = 0.3)

Examples

if (sits_run_examples()) {
# obtain the DEM cube
    dem_cube_19HBA <- sits_cube(
        source = "MPC",
        collection = "COP-DEM-GLO-30",
        bands = "ELEVATION",
        tiles = "19HBA"
        )
# plot the DEM reversing the palette
    plot(dem_cube_19HBA, band = "ELEVATION")
}
