ABSTRACT
The capabilities of small, primarily single-user computers have increased to the
point where serious attention to the use of these systems as image display and processing
stations is warranted. The addition of satellite display and processing to the existing
Navy Oceanographic Data Distribution System (NODDS) can represent significant
enhancement to the forecasting mission of Naval Oceanography Command Detachments
and Facilities. This thesis outlines and demonstrates an approach to adding image
functions to NODDS. Software has been written to display Defense Meteorological
Satellite Program (DMSP) visual and infrared images within the NODDS software
environment. Routines have also been developed to provide enhancement ofthe imagery.
The requirements for communicating the imagery are addressed and supported by the
testing of image transfer times. Finally, plans for system improvement and operational
implementation are discussed.
