In hrvg/statisticalRoughness: Estimation of roughness exponents across scale for large areas

Description

Wrapper function to derive the anisotropy exponent from a non-rotated raster

Usage

get_zeta(
  rstr,
  raster_resolution,
  nbin = 20,
  .Hann = TRUE,
  .quantile_prob = c(0.9999),
  .prob = 0.999,
  full = FALSE
)

Arguments

rstr	Raster object
raster_resolution	numeric the resolution of rstr in meters
nbin	numeric, the number of bins
.Hann	logical, if TRUE performs a Hann windowing, default to TRUE, passed to fft2D()
.quantile_prob	vector of quantile probabilities, default to c(0.9999), passed to filter_spectral_power_matrix()
.prob,	numeric the value of the probabilities passed to quantile(), passed to filter_alpha()
full,	logical if TRUE all results are returned, else, the default, results of interest are returned

Value

a data.frame
