get.section.densities.3d {eRTG3D} | R Documentation |
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.

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