EXTERNAL COORDINATE SYSTEM
    An integrated system governing control of all manufacturing, repair,
and operational structural reference points exists for the USS Enterprise and
all other Starfleet vessels. The system utilizes a standard three-dimensional
vertex and vector measuring scheme, with centimeters as its operative
value. The three axes are labeled X, Y, and Z. The X axis runs port-starboard,
with +X to starboard. The Y axis runs dorsal-ventral, with +Y to dorsal. The Z
axis runs fore-to-aft, with +Z to aft. Note that this is opposite in sign to
translational maneuvers, which consider +Z to be in the direction of flight.
    All single points, vectors, and planes can be determined with this
scheme, creating a common ground for structural topics. The Enterprise is
considered to have three vessel configurations: Docked, Saucer Module,
and Battle Section. Each configuration maintains a specific measurement
origin, designated by the XYZ value of the forwardmost structure. For
example, the center forward edge of the Saucer Module is labeled XYZΩ
0,0,0. Coincidentally, it is also the origin for the docked vessel and can be
labeled XYZδ 0, 0, 0. The origin for the Battle Section, designated XYZ⌡ 0, 0, 0,
also corresponds to a point on the docked vessel as XYZ⌡ 0,0, 0, also
corresponds to a  point on the docked vessel as XYZδ 0, -1676, 25146,
meaning that the Battle Section origin is at 25146 cm aft of the ship╒s forward
edge and 1676 cm below.
    Specific components, such as the warp engine nacelles, are given
their own origins and coordinate values, and these will also have
corresponding values relative to their parent assemblies. For example, the
origin of the port warp nacelle is labeled XYZ╫ 0, 0, 0. This point, relative to
the Battle Section origin, is XYZ⌡ ╤12954, ╤1524, 13716.
    Planes passing through the different vessel configurations are
labeled according to their axes. XY planes of the docked starship run
vertically and laterally, XZ planes intersect the ship parallel with the saucer
equator, and YZ planes run vertically and fore-to-aft. Planes may be called
out as existing at specific XYZ station points, and coordinates may be given
within that plane, especially in locating key starship components or
processes.
    Normally, all coordinate and planar data are manipulated by the main
computers in their monitoring and repair tasks and are available to
Engineering crew members as an option in considering exact three-
dimensional relationships within the ship.

INTERNAL COORDINATE SYSTEM
    Structures and objects within the USS Enterprise spaceframe are
located with the following coordinate system. Intraship locator addresses
are based on a fifteen-digit code which follows the form: ╥12-1234-
000/000/000.╙
    The first group of two digits refers to the deck number. Possible
values within the Primary Hull range from 01 (Deck 1, the Main Bridge) to 16
(the captain╒s yacht docking port on the underside of the saucer). Within the
Engineering Hull, deck numbers range from 08 (the Battle Bridge at the top of
the dorsal) to 42 (Deck 42, the bottom of the Engineering Hull).
    The second group of four digits specifies the sector and
compartment number. For locations within the Primary Hull, the first two
digits of this group refer to one of 36 ten-degree sectors.
    For locations within the Engineering Hull, the first digit of this group is
always a 5, with the second digit designating one of ten sectors. A first digit
of 6 indicates a location within the port warp nacelle or pylon, and a first digit
of 7 indicates a location within the starboard warp nacelle or pylon.
    The third and fourth digits in this second group indicate the
compartment or station number within the sector.
    Note that the first and second group of the locator address (totaling
six digits) are generally used as room designator numbers within the
habitable volume of the spacecraft. By keeping in mind this general scheme
of room and compartment numbering, it is possible for crew members to
locate virutally any room on board the ship by use of the internal coordinate
system.
    The final group of three three-digit numbers refers to the XYZ
coordinate address within a compartment. In cases where greater precision
is required, decimal values are appended to each of the XYZ coordinates.  ╞
