is.beam: Determine coordinate system for acoustic-doppler device

Description

Determine coordinate system for acoustic-doppler device

Usage

is.beam(x)
is.xyz(x)
is.enu(x)
coordinate(x)

Arguments

x

an oce object that inherits from either adp or adv.

Value

• The is. functions return TRUE if the object inherits from adv or adp, and is of the stated coordinate type, or FALSE otherwise. coordinate return a string indicating the coordinate system, beam (velocities oriented along acoustic beams), xyz (velocities in a cartesian coordinate system tied to the instrument, or its pressure case), or enu (a cartesian coordinate system with one component pointing east, the second north, and the third up.

Details

These functions work by checking the value of x@metadata$oce.coordinate, the main purpose being to prevent users from having to know the difference between that item and others of similar names.
