Which search method may employ infrared film for discovery of gravesites?

• A. Aerial Search
• B. Point-to-Point
• C. Area Search
• D. Circular or Spiral Search

Answer: (A)

Infrared imaging is most effective for wide-area screening when you’re trying to spot subsurface or moisture-related anomalies across large terrains. Using aircraft allows you to cover expansive areas quickly, which is why infrared film is commonly associated with aerial search. Disturbed soil from gravesites can create subtle differences in heat retention or moisture that infrared can reveal from above, enabling investigators to pinpoint probable locations for ground verification.

Ground-based patterns like point-to-point, area, or circular/spiral searches focus on systematic coverage of a known area or following clues on foot or with vehicles. They don’t typically rely on infrared imagery to locate gravesites, making aerial search the best fit for employing infrared film.
