Which term describes the numerical system used to track positions in surveillance?

• A. Lane Numbers
• B. Grid Coordinates
• C. Reference Points
• D. Time Stamps

Answer: (A)

Tracking positions in surveillance relies on mapping a location to a systematic grid on a map. That grid uses coordinates to pinpoint a precise spot, like a row and column reference, so analysts can communicate and locate things quickly and unambiguously. This is exactly what grid coordinates accomplish as a numerical tracking system.

Lane numbers are tied to specific road lanes and don’t provide a universal way to mark any arbitrary position on a map. Time stamps record when an event occurs, not where it happened. Reference points are landmarks used for orientation, not a standardized numerical location system. So the term that best describes the numerical system used to track positions is grid coordinates.
