Multimedia Visualisation of Massive Military Datasets (Visualisation multimedia des jeux de donnees militaires massifs)

摘要

The objective of IST-021/RTG-007 was to gain visualisation knowledge in common which will help facilitate the effective development of internationally useful systems. The RTG undertook four major tasks: evaluate and update visualisation systems principles developed by IST-013/RTG-002; deliver a workshop in 2002 on multimedia information visualisation, the results of which helped to guide the subsequent work of the group; propose a lecture series on Multimedia Information Visualisation for delivery in 2005 (this task was cancelled); deliver a workshop in 2004 on Visualisation and the Common Operational Picture. Evaluations of two visualisation systems were attempted, the Norwegian NORCCIS II and the Canadian VITA. Two approaches that had been proposed to IST-021/RTG-007 (The VisTG Reference Model, and the Smestad guidelines based on information-theoretic principles) were used with NORCCIS II, but both evaluations proved complicated and were not completed in the limited time made available. Nevertheless, both attempts did find areas of potential improvement, but these improvements had already been noted by the operators and were not newly discovered by the IST-021/RTG-007 approaches. As for VITA, an 'appreciation' was performed using the VisTG Reference Model that showed issues and benefits both with the evaluation process and with VITA. Both approaches to evaluation suggested that the complexity of real system structures would usually present problems in keeping track of cross influences. Too much data was generated and too many relationships observed for a manual approach to be effective.
