surfaceAreaRatio: Surface Area Ratio (Surface Texture)

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

Description

[surfaceAreaRatio()] calculates scalable slope position by subtracting a focalmean raster from the original elevation raster.

Usage

surfaceAreaRatio(elevation = NULL, slope = NULL, size = 3,
  zscale = "1.0", output = NULL, load_output = TRUE, quiet = TRUE, ...)

Arguments

elevation	RasterLayer containing elevation values
slope	(optional) RasterLayer containing slope values. Default: NULL
size	analysis window (rectangle). Default: 3
zscale	Multiplicative factor to convert elevation units to horizontal units. Default: "1.0"
output	(optional) file name to save output. Default: NULL
load_output	If TRUE, function output file will be loaded into R. Default: TRUE
quiet	IF FALSE, console messages are shown. Default: TRUE
...	optional parameter for [RQGIS::run_qgis()]

Value

RasterLayer surfaceAreaRatio
