: Variations in tone directly represent distinct minerals, soils, and water levels. For instance, high iron content absorbs light around 550 nm, creating specific visual anomalies.

To isolate and highlight these features, experts utilize targeted imaging strategies:
: The texture of a surface influences how light or radar reflects. Fine grain sizes often create high backscattering, causing smooth surfaces to appear darker and rougher surfaces to appear brighter.
Geological remote sensing depends on extracting information from image characteristics to map surface conditions. The fundamental elements analyzed include:
