rdh {habtools}

Calculate rugosity, fractal dimension, and height for a DEM

Description

Calculate rugosity, fractal dimension, and height for a DEM

Usage

rdh(
  data,
  lvec,
  method_fd = "hvar",
  method_rg = "area",
  parallel = FALSE,
  ncores = (parallel::detectCores() - 1),
  ...
)

Arguments

data

A dem of class RasterLayer.

lvec

Scales to use for calculation.

method_fd

method for the calculation of rugosity and fractal dimension. Can be "hvar", "sd", "cubes", or "area". Defaults to "hvar".

method_rg

Method to be used for the rugosity calculation. Defaults to "area".

parallel

Logical. Use parallel processing? Defaults to FALSE.

ncores

Number of cores to use if parallel = TRUE.

...

Additional arguments see fd().

Details

Uses area method for rugosity and hvar method for fractal dimension calculations as default.

Value

A dataframe with the three complexity metrics.
