Which pairing correctly matches Still Imagery with its described use?

• A. Broad area of surveillance, undetectable collection
• B. Works only at night
• C. Low cost and wide availability
• D. Requires continuous power

Answer: (A)

Still imagery excels at broad-area surveillance because a single photograph can cover a large geographic footprint, providing a stable reference for monitoring changes over time. This makes it a practical way to observe wide regions and build baselines without the continuous stream of video. The collection can be relatively covert since many still images come from passive sensors on overhead platforms, making it less noticeable to the subject than ongoing video. It isn’t limited to night use—images can be captured in daylight or with specialized sensors at night. Costs and availability vary with the platform and sensor, so they aren’t defining traits of still imagery. Continuous power needs relate to the platform operating the sensor, not to the concept of still imagery itself.
