roughnessIndex: Roughness Index (Surface Texture)

In raff-k/GeoMorphTB: Computing various gradient and geomorphometric parameters

Description

[roughnessIndex()] as standard deviation of residual topography (Cavalli et al. 2008).

Usage

roughnessIndex(elevation = NULL, size = 3, output = NULL,
  load_output = TRUE, return_weighted = FALSE, quiet = TRUE, ...)

Arguments

elevation	RasterLayer containing elevation values
output	(optional) file name to save output. If return_weighted is TRUE, output should be vector containing two file names. Default: NULL
load_output	If TRUE, function output file will be loaded into R. Default: TRUE
return_weighted	If TRUE roughness index is normalized by max-value. Default: FALSE
quiet	IF FALSE, console messages are shown. Default: TRUE
...	optional parameter for [RQGIS::run_qgis()]

Value

RasterLayer roughness index. If return_weighted is TRUE, a list is returned containing roughness index [[1]] and normalized roughness index [[2]]
