move (version 2.1.0)

dynBGB: Calculation of the dynamic Bivariate Gausian Bridge

Description

This function creates a utilization distribution according to the Bivariate Gaussian Bridge model. It returns an object of the class dynBGB-class.

Arguments

move

the move object or variance object used for calculating the ud if a .MoveTrackSingle object is supplied this is converted into a dBGBvariance object using the dynBGBvariance function

raster

either the raster used for UD calculation or the resolution of the raster used for UD calculation

locErr

the location errors used for the calculation

Examples

# NOT RUN {
data(leroy)
leroy <- leroy[230:265,]

## change projection method to aeqd and center the coordinate system to the track
dataAeqd <- spTransform(leroy, CRSobj="+proj=aeqd +ellps=WGS84", center=TRUE)

dBGB <- dynBGB(dataAeqd, locErr=9, raster=10, ext=2.15, windowSize=31, timeStep=6, margin=15)
plot(dBGB, col=hsv(sqrt(1:700/1000)))
