relies on the analysis of reflected and emitted electromagnetic radiation from the Earth's surface to map and monitor geological features from a distance . 🔍 Key Feature Elements
Geological remote sensing depends on extracting information from image characteristics to map surface conditions. The fundamental elements analyzed include: Remote Sensing Geology
: Collecting data across multiple narrow bands allows algorithms to match localized spectral curves with known mineral libraries (such as the USGS Spectral Library ). relies on the analysis of reflected and emitted
: 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. : The texture of a surface influences how
: Specific electromagnetic wavelengths (from visible to thermal infrared) react to intra-atomic electronic transitions and inter-atomic bond strengths. This reveals distinct chemical properties of rocks and minerals.
