To capture remote-sensing imagery, use ______ technology.

To capture remote-sensing imagery, use ______ technology.

• A. Electro Optical (EO)
• B. Infrared (IR)
• C. Radar
• D. Sonar

Answer: (A)

Remote-sensing imagery from drones is typically captured with sensors that record visible light and, often, near-infrared reflected from the surface. Electro Optical (EO) sensors are basically digital cameras optimized for this kind of data, producing standard color or grayscale imagery that looks like a photograph and provides high spatial detail useful for mapping, inspection, and analysis. Infrared sensors capture heat and produce thermal imagery, which is a different data type. Radar uses microwave energy to create radar imagery that can see through some weather and lighting conditions, but it’s a distinct modality with different data characteristics. Sonar is used underwater, not for aerial sensing. So for capturing the familiar remote-sensing imagery used in many drone applications, Electro Optical (EO) technology is the best fit.
