Which search method can utilize infrared film to discover gravesites?

The ability to utilize infrared film to discover gravesites aligns with the Aerial Search method. Infrared technology can detect differences in heat that may indicate disturbances in the ground, such as graves. The use of aerial resources allows investigators to cover large areas quickly and efficiently while capturing images that reveal these temperature variations.

In the context of finding gravesites, this method enables law enforcement or investigators to identify locations that may not be visible through standard ground searches. Infrared imaging can highlight areas where soil has been recently disturbed, leading to more efficient identification of potential grave locations.

Each search method has distinct purposes and applications; aerial searches are particularly effective in large or challenging terrains where the human eye may not detect subtle signs of burials. This makes the use of aerial infrared technology a powerful tool in criminal investigations related to remains discovery.
