Heat map

Description

Calculates a heat map, or kernel density estimation (KDE), for an input point set.

Usage

wbt_heat_map(
  input,
  output,
  weight_field = NULL,
  bandwidth = "",
  kernel = "quartic",
  cell_size = "",
  base = NULL,
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Arguments

`input`	Name of the input points shapefile.
`output`	Name of the output raster image file.
`weight_field`	Optional name of the attribute containing point weight.
`bandwidth`	Bandwidth (metres).
`kernel`	Kernel type; one of 'uniform', 'triangular', 'epanechnikov', 'quartic', 'triweight', 'tricube', 'gaussian', 'cosine', 'logistic', 'sigmoid', 'silverman'.
`cell_size`	Optionally specified cell size of output raster, in metres. Not used when base raster is specified.
`base`	Optionally specified input base raster file. Not used when a cell size is specified.
`wd`	Changes the working directory. Default: `NULL` will use the value in WhiteboxTools settings, see `wbt_wd()` for details.
`verbose_mode`	Sets verbose mode. If verbose mode is `FALSE`, tools will not print output messages. Default: `NULL` will use the value in WhiteboxTools settings, see `wbt_verbose()` for details.
`compress_rasters`	Sets the flag used by 'WhiteboxTools' to determine whether to use compression for output rasters. Default: `NULL` will use the value in WhiteboxTools settings, see `wbt_compress_rasters()` for details.
`command_only`	Return command that would be executed by `system()` rather than running tool. Default: `FALSE`.
