Which type of UAS image highlights differences in temperature most clearly?

• A. Elevation map
• B. Thermogram
• C. Multispectral
• D. Panchromatic

Answer: (B)

Thermal infrared imaging is used to visualize how heat is distributed across a scene. A thermogram maps surface temperatures into colors, so differences in heat show up as distinct color patterns. Hotter areas appear with colors indicating higher temperatures, while cooler areas appear differently, making subtle temperature variations easy to spot. This direct representation of heat is what makes a thermogram the best choice forHighlighting temperature differences.

Elevation maps show height information, not temperature. Panchromatic images are high-resolution black-and-white views from visible light, useful for detail but not for temperature. Multispectral images capture several light bands to analyze material properties and vegetation health, but they don’t directly map temperature in the same way thermal imagery does.
