spTransform: Transform Move object projection method

In move: Visualizing and Analyzing Animal Track Data

Description

The spTransform function transforms the coordinates stored in the Move object from the default longlat coordinates to the default aeqd (Azimuthal Equi-distance) projection or a different projection.

Usage

## S4 method for signature 'Move,character'
spTransform(x,CRSobj,center=FALSE)
## S4 method for signature 'Move,missing'
spTransform(x,center=FALSE,...)

Arguments

x	a Move or a MoveStack object
CRSobj	a CRS like character that describes the projection method to which the coordinates should be transformed, if missing "+proj=aequd" is used as default value
center	logical, if TRUE the center of the coordinate system is the center of the track; FALSE is default
...	for additional arguments

Details

The spTransform function transforms the coordinates of a Move object by default from "+proj=longlat" to "+proj=aeqd". In this format the coordinates can be used by the brownian.bridge.dyn function.
If center is TRUE the center of the coordinate system is set to the center of the track.

Examples

## create a Move object
data(leroy)
## transform the Move object by default into "+aeqd" projection method 
## and center the coordinate system
spTransform(leroy, center=TRUE)

## transform the Move object into another projection method, like mollweide
spTransform(leroy, CRSobj="+proj=moll +ellps=WGS84")

##check projection method
proj4string(leroy)
