In ErikKusch/KrigR: Downloading, Aggregating, and Kriging of ECMWF CDS-Data

Visualise raster data and overlay sf polygons if desired.

Description

Use the ggplot2 plotting engine to easily create visualisations of raster data - like the ones obtained using CDownloadS(...) - and overlay sf polygon data if desired.

Usage

Plot.SpatRast(
  SpatRast,
  SF,
  Dates,
  Legend = "Air Temperature [K]",
  COL = viridis::inferno(100),
  Size = 1,
  Shape = 1
)

Arguments

SpatRast	SpatRast object to visualise.
SF	Optional. SF object which to overlay.
Dates	Optional. Character vector of labels to apply to each layer of the SpatRast. By default, the content of the terra::time() field of the supplied SpatRast object.
Legend	Colour label legend.
COL	Colour palette.
Size	Optional. Size of SF overlay.
Shape	Optional. Shape of SF overlay if points.
