enuToOtherAdv {oce} | R Documentation |
Convert ADV velocity components from an enu-based coordinate system to another system, perhaps to align axes with the coastline.
enuToOtherAdv(x, heading=0, pitch=0, roll=0, debug=getOption("oceDebug"))
x |
an object of class |
heading |
number or vector of numbers, giving the angle, in degrees, to be added to the heading. See “Details”. |
pitch |
as |
roll |
as |
debug |
a flag that turns on debugging. Set to 1 to get a debugging information. |
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.
