beamToXyzAdv: Convert ADV from beam coordinates to xyz coordinates

Description

Convert ADV velocity components from a beam-based coordinate system to a xyz-based coordinate system.

Usage

beamToXyzAdv(x, debug=getOption("oceDebug"))

Arguments

x

an object of class "adv".

debug

a flag that, if non-zero, turns on debugging. Higher values yield more extensive debugging.

Details

The coordinate transformation is done using the transformation matrix contained in x$metadata$transformation.matrix, which is normally inferred from the header in the binary file. If there is no such matrix (e.g. if the data were streamed through a data logger that did not capture the header), beamToXyzAdv the user will need to store one in x, e.g. by doing something like the following: x$metadata$transformation.matrix <- rbind(c(11100, -5771, -5321), c( 291, 9716, -10002), c( 1409, 1409, 1409)) / 4096 .
