Which search method may employ infrared film to discover gravesites?

• A. Point-to-Point
• B. Aerial Search
• C. Quadrant Search
• D. Area Search

Answer: (B)

Infrared imaging from an aircraft lets you survey large areas quickly. Disturbed soil around gravesites often changes moisture content and heat retention, creating detectable differences in infrared images that aren’t visible to the naked eye. From above, you can cover vast terrain and spot subtle anomalies over time, then ground teams can verify those spots. Ground-based methods focus on visible clues and step-by-step searches on the surface and don’t typically use aerial infrared screening, so they’re less efficient for locating buried features over large areas.
