get.densities.3d {eRTG3D} R Documentation

## Extract tldCube and autodifference approximation functions

### Description

Creates a list consisting of the three 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 turn angles, lift angles and step lengths with a lag of 1 to maintain minimal level of autocorrelation in each of the terms. Additionally also the distribution of the flight height over the ellipsoid (absolute) and the distribution of flight height over the topography (relative) can be included.

### Usage

get.densities.3d(
turnAngle,
liftAngle,
stepLength,
deltaLift,
deltaTurn,
deltaStep,
heightEllipsoid = NULL,
heightTopo = NULL,
maxBin = 25
)


### Arguments

 turnAngle turn angles of the track (t) liftAngle lift angles of the track (l) stepLength stepLength of the track (d) deltaLift auto differences of the turn angles (diff(t)) deltaTurn auto differences of the lift angles (diff(l)) deltaStep auto differences of the step length (diff(d)) gradientAngle NULL or the gardient angles of the track heightEllipsoid flight height over the ellipsoid (absolute) or NULL to exclude this distribution heightTopo flight height over the topography (relative) or NULL to exclude this distribution 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 flight height distribution functions)

### Examples

niclas <- track.properties.3d(niclas)[2:nrow(niclas), ]
P <- get.densities.3d(
turnAngle = niclas$t, liftAngle = niclas$l, stepLength = niclas$d, deltaLift = diff(niclas$t), deltaTurn = diff(niclas$l), deltaStep = diff(niclas$d),
gradientAngle = NULL, heightEllipsoid = NULL, heightTopo = NULL, maxBin = 25
)
