The GEODATA Display System (or GEODATA) is a set of tools, executing
on a Thinking Machines Corporation Connection Machine (CM), for
displaying information which typically relates to specific geographic
positions.  Commonly this will be the results of acoustic or
oceanographic simulation model runs.  Such simulations may produce,
for example, sound speed or intensity of acoustic energy at regularly
spaced ocean points and depths.  Since the set of applicable
simulations is not defined, a general capability, and not limited to
or specialized for ocean displays, is needed.

The most basic GEODATA capability is to display simulation data
against a two dimensional map or three dimensional terrain background.
GEODATA software allows applications to select specific regions for
close examination, to control how data objects are represented, and
what transformations are applied to form the display.  The software
supports an interactive mode with the user manipulating the display
through GEODATA primitives or through an X Windows control panel.

GEODATA is a library of routines.  It is intended that display code,
in the form of function and subroutine calls, be easily inserted into
applications and that essentially no advance planning be required by
the simulation developer.

GEODATA was a project at the Connection Machine Facility of the
Naval Research Laboratory under the direction of Dr. Henry Dardy.
