get.section.densities.3dR Documentation

Extract tldCube and autodifferences functions from track sections

Description

Creates a list consisting of the 3 dimensional probability distribution cube for turning angle, lift angle and step length (turnLiftStepHist) as well as the uni-dimensional distributions of the differences of the turning angles, lift angles and step lengths with a lag of 1 to maintain minimal level of autocorrelation in each of the terms.

Usage

get.section.densities.3d(
  trackSections,
  gradientDensity = TRUE,
  heightDistEllipsoid = TRUE,
  DEM = NULL,
  maxBin = 25
)

Arguments

trackSections

list of track sections got by the track.split.3d function

gradientDensity

logical: Should a distribution of the gradient angle be extracted and later used in the simulations?

heightDistEllipsoid

logical: Should a distribution of the flight height over ellipsoid be extracted and later used in the sim.cond.3d()?

DEM

a raster containing a digital elevation model, covering the same extent as the track sections

maxBin

numeric scalar, maximum number of bins per dimension of the tld-cube (turnLiftStepHist)

Value

A list containing the tldCube and the autodifferences functions (and additionally the height distribution function)

Examples

get.section.densities.3d(list(niclas[1:10, ], niclas[11:nrow(niclas), ]))
