Which DSIG category includes GEOINT, SIGINT, ACINT, MASINT?

Which DSIG category includes GEOINT, SIGINT, ACINT, MASINT?

• A. Functional
• B. Environmental
• C. Physical
• D. Cognitive

Answer: (C)

The question tests recognizing that those intelligence disciplines are grouped by the physical phenomena they measure with sensors. The Physical category covers intelligence gathered by detecting and measuring real-world signals and signatures with hardware. Geospatial intelligence uses imagery and geospatial data from sensors such as cameras, LiDAR, and radar to map and analyze the Earth's surface, which are physical measurements. Signals intelligence intercepts electronic signals in the environment, relying on antennas and receivers to capture real electromagnetic phenomena. Acoustic intelligence studies sounds and vibrations in the air or ground, a clear physical phenomenon. Measurement and Signature Intelligence encompasses a wide range of sensor-based measurements of physical signatures, from radar and infrared to chemical and nuclear signatures. Since all four rely on observing physical phenomena through sensors, they fit best in the Physical category. (Environmental would cover weather-related data, Cognitive would involve human factors, and Functional relates to operational functions rather than sensing physical reality.)
