Value

No value is returned

Arguments

move.dat

Details

Writes 3D points for observed locations for move steps. Currently, the list argument control only has one element z.scale used to scale the z-coordinates.

Examples

library(raster)
data(condor)
mv.dat <- initializeMovementData(condor$time, condor$x, condor$y, 
z.obs=condor$z, sig2obs=25.0, sig2obs.z=81.0, t.max=65.0)

data(condordem)
cell.sz <- mean(res(condordem))
ext <- extent(condordem)
nx <- ncol(condordem)
ny <- nrow(condordem)
mkde.obj <- initializeMKDE3D(ext@xmin, cell.sz, nx, ext@ymin, cell.sz,
ny, min(values(condordem), na.rm=TRUE), 30.0, 100)

writeObservedLocationVTK(mv.dat, mkde.obj,
"Example California condor locations", "condor_locations.vtk")
