Abstract:
The Army's Common Picture of the Battlefield will produce immense amounts
of data associated with tactical goals and options,
dynamic operations, unit and troop movement, and general battlefield
information. These data will come from sensors (in real-time) and from
simulations and must be positioned accurately on high-fidelity 3-D terrain.
This paper describes a 4-D symbology (3-D symbols plus time-dependence) for
battlefield visualization that addresses>these needs. It is
associated with the Army's 2-D symbols for operations and tactics so that
the information content of this symbolic structure is retained.>A
hierarchy is developed based on military organization to display this
symbology. Using this hierarchy, even complex battlefield scenarios can be
displayed and explored in real-time with minimal clutter. The user
may also move units around by direct manipulation, define paths, create or
delete hierarchical elements, and make other interactions. To strengthen
the capacity for distributed simulations and for using sensor
information from multiple sources, DIS capability has been integrated
with the symbology for dynamic updates of position, direction and speed, and
hierarchical structure. The paper will also discuss how the techniques
used here can be applied to general (non-military) organizational structures.
