reproduce.track.3d {eRTG3D}

Reproduce a track with the eRTG3D

Description

Simulates n tracks with the geometrical properties of the original track, between the same start and end point.

Usage

reproduce.track.3d(
  track,
  n.sim = 1,
  parallel = FALSE,
  error = TRUE,
  DEM = NULL,
  BG = NULL,
  filterDeadEnds = TRUE,
  plot2d = FALSE,
  plot3d = FALSE,
  maxBin = 25,
  gradientDensity = TRUE
)

Arguments

track

data.frame with x,y,z coordinates of the original track

n.sim

number of simulations that should be done

parallel

logical: run computations in parallel (n-1 cores)? Or numeric: the number of nodes (maximum: n - 1 cores)

error

logical: add error term to movement in simulation?

DEM

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

BG

a raster influencing the probabilities.

filterDeadEnds

logical: Remove tracks that ended in a dead end?

plot2d

logical: plot tracks on 2-D plane?

plot3d

logical: plot tracks in 3-D?

maxBin

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

gradientDensity

logical: Should a distribution of the gradient angle be extracted and used in the simulations (get.densities.3d)?

Value

A list or data.frame containing the simulated track(s) (CERW).
