To determine the last known location of victims, which tool should be used?

• A. Aerial photos
• B. Local maps
• C. Satellite weather reports
• D. Census data

Answer: (B)

Determining the last known location of victims relies on precise, on-site references that map the built environment. Local maps provide the most detailed, current depiction of the structure’s interior and layout—floor plans, room numbers, stairwells, corridors, and access routes—so you can anchor the search to the exact areas where a victim could have been identified last.

Aerial photos offer a broad view of the site and can help spot external hazards or overall layout, but they lack interior detail and can be out of date, making them less reliable for pinpointing a specific room or floor. Satellite weather reports focus on environmental conditions, not where someone might be inside a collapsed structure. Census data gives demographic information, not current positioning in a specific incident. Therefore, local maps are the best tool for this task.
