Terrain Analysis and Visualization Workstation

Abstract:

The Terrain Analysis and Visualization Workstation will extract
terrain height information from multi-sensor imagery, produce a
co-registered set of orthorectified images, and fuse the imagery
with existing hydrological, transportation, and land-use
datasets.

The resulting data will be presented to the user through a coherent
set of 3-dimensional visualization, manipulation, and measurement
tools. An important innovation in the workstation is the
representation of sensor models and sensor trajectories by an
object-oriented class library. Use of this class library and the
associated photogrammetric "methods" that are defined on the object
classes will provide a mechanism for supporting additional sensors
that are available in the future. It will also allow the user to
visually simulate the observations from imaging instruments through
the interactive modification of sensor types, flight paths, and
platform orientation.

The workstation will be a source of orthorectified imagery for
GIS users in the private sector and all levels of government.  It
will be useful to the military as a tool for producing image maps
from multi-sensor imagery. Such maps can be made cheaply and with
a rapid turn-around time.
