Observational

20% weight

Observational data captures what was actually seen, where, and by whom. This is the largest category by field count, spanning precise geospatial coordinates, temporal data, detailed object characteristics (shape, size, color, surface features, emissions), movement behavior (speed, maneuvers, formation, aircraft interactions), and comprehensive witness profiles including credibility assessments, professional backgrounds, security clearances, and testimony consistency. The richness of observational data determines whether an event can be meaningfully compared to others.
