o The Aquaticus field is assumed to be a rectangle.
o The location, rotation, and dimensions are considered to be fluid.
o They may change based on tide, sea state or other environmental
  factors, especially at Jervis Bay.

o There are two Aquaticus coordinate systems: (1) Absolute, and (2)
  relative to a vehicle's home side. They are depicted below.

o The absolute coodinates are determined from the jerop.sh script in
  moos-ivp-aquaticus/scripts. The set of coordinates are seeded from
  - NW location
  - Field Width and Depth (by default 160x80)
  - Angle of rotation (by default 149 degrees, aligned w Jervis shoreline)

o Once the Absoluted coordinates are defined, the relative coordinates
  are mapped to the absolute coordinates depending on which side is the
  home side.

o For example, the North Flag is always at Location NCF and the South
  flag is always at Location SCF (South-Center-FlagLine)
  Ownship own flag is always at CF, and the other flag is always at CFX.

o All Shell variables have a "T" counterpart. For example the NCF var
  may be:
    NCF  = x=23.4,y=99.8, and
    NCFT = 23.4,99.8
  This is to support places where one format is required over the other.
