In ggRaver/Lslide: Functions for object-oriented image analysis in landslide science

Sky-view factor as a relief visualization technique

Description

This function enables the possibility to directly address the stand-alone Relief Visualization Toolbox of ZAKSEK et al. (2011).

Usage

skyViewFactor(path.software, path.input, options_overwrite = 1,
  options_exaggeration_factor = 1, hillshading = c(0, 315, 35, 0),
  multiple_hillshading = c(0, 16), pca_hillshading = c(0, 3),
  slope_gradient = 0, simple_local_relief = c(0, 20),
  sky_view_factor = c(1, 16, 10, 0, "low"), anisotropic_svf = c(0,
  "low", 315), positive_openness = 0, negative_openness = 0,
  sky_illumination = c(0, "overcast", 250, 100), local_dominance = c(0,
  10, 20), quiet = TRUE)

Arguments

path.software	path where software is located
path.input	path to input file
quiet	option to control outputs in console during process. Default: TRUE
other...	see Relief Visualization Toolbox (last call: 13-04-2017)

Note

• output is located in input directory

• compatible to Relief Visualization Toolbox version 1.3, RVT 1.3 (last call: 13-04-2017)
