<ul><li><b>Scope and content:</b>  The Cluster Analysis Map is a map of Vietnam, overlaid with a grid system, upon which are plotted and marked by colored push-pins, the locations of live sightings.  The map was created by the professional staff of the select committee as part of an alternative type of analysis of sightings to that used by the Defense Intelligence Agency.  The objective of the analysis was to determine if live sightings would cluster at certain locations when plotted on a map, especially around areas known to have Prisoner of War (POW) camps.  A summary of the Cluster Map methodology begins on page 181 of the select committee's final report.</li></ul></div>
