Visualize LCZ parameters

Source: R/lcz_plot_parameters.R
lcz_plot_parameters.Rd

This function plots the parameters of an Local Climate Zone map.

Usage

lcz_plot_parameters(
  x,
  iselect = "",
  all = FALSE,
  inclusive = FALSE,
  isave = FALSE,
  save_extension = "png",
  ...
)

Arguments

x

The LCZ map in SpatRaster in a stack format.

iselect

Code vector. Specify one or more parameter:

  • TRCmean: Mean Terrain Roughness class

  • TRCmax: Maximum Terrain Roughness class

  • TRCmin: Minimum Terrain Roughness class

  • SADmean: Mean Surface Admittance

  • SADmax: Maximum Surface Admittance

  • SADmin: Minimum Surface Admittance

  • SALmean: Mean Surface Albedo

  • SALmin: Minimum Surface Albedo

  • AHmean: Mean Anthropogenic Heat Output

  • AHmax: Maximum Anthropogenic Heat Output

  • AHmin: Minimum Anthropogenic Heat Output

  • z0: Roughness Length class

all

Logical, specifying whether to save all selected parameters into LCZ4r_output. Default is FALSE.

inclusive

Set to TRUE to a colorblind-friendly palette.

isave

Logical, indicating whether to save the plot to your directory. Default is FALSE.

save_extension

File format for saving the plot. Options: "png", "jpg", "jpeg", "tif", "pdf", "svg" (default is "png").

...

An optional modify axis, legend, and plot labels: subtitle, and caption. It does not work with title.

Value

A plot of the selected LCZ parameters in ggplot2 format

Examples

if (FALSE) { # \dontrun{
# Plot the mean Sky View Factor (SVFmean) for your city
lcz_plot_parameters(lcz_map, iselect = "SVFmean")

# Plot multiple parameters and save them to the LCZ4r_output directory
lcz_plot_parameters(lcz_map, iselect = c("BSFmean", "AHmean"))
} # }
