enuToOtherAdv: Convert ADV from east-north-up coordinates to other coordinates

Description

Convert ADV velocity components from an enu-based coordinate system to another system, perhaps to align axes with the coastline.

Usage

enuToOtherAdv(x, heading=0, pitch=0, roll=0)

Arguments

x

an object of class "adv".

heading

number or vector of numbers, giving the angle, in degrees, to be added to the heading. See Details.

pitch

as heading but for pitch.

roll

as heading but for roll.

Details

The supplied angles specify rotations to be made around the axes for which heading, pitch, and roll are defined. For example, an eastward current will point southeast if heading=45 is used. The returned value has heading, pitch, and roll matching those of x, so these angles retain their meaning as the instrument orientation.

NOTE: this function works similarly to xyzToEnuAdv, except that in the present function, it makes no difference whether the instrument points up or down, etc.
