Which data product is used to visualize heat signatures?

• A. Optical mosaic
• B. Elevation model
• C. Sonar image
• D. Thermogram

Answer: (D)

Thermal imaging translates infrared energy into a temperature map, and the data product that visualizes this temperature distribution as colors is a thermogram. It highlights heat signatures, showing hot spots and temperature gradients in the scene, which is exactly what you need to identify where heat is concentrated or transferred. Optical mosaics are stitched visible-light images, elevation models show terrain height, and sonar images map underwater features—none of these depict temperature data, so they aren’t used to visualize heat signatures.
