What color represents dry areas in infrared imaging?

In infrared imaging, dry areas are typically represented by black or dark shades. This representation is due to the way dry surfaces reflect infrared light compared to moist or vegetated areas. Dry soil or desert regions usually have a lower moisture content, which results in less infrared reflection, causing these areas to appear darker in imagery. Black or dark tones in infrared images indicate a strong absorption of infrared light, which is a characteristic feature of dry land.

The other colors mentioned serve different purposes in infrared imaging. For instance, green often signifies vegetation or areas with abundant moisture, while red is associated with features like water bodies or certain types of plant life depending on the specific imaging techniques used. Blue typically represents areas with even various moisture levels or different soil types. Understanding this color representation helps researchers and practitioners analyze land use, vegetation health, and environmental changes effectively.
