Spectral Analysis
Spectral Index
A mathematical combination of two or more spectral bands designed to highlight a specific surface property. Common indices include NDVI (vegetation), NDWI (water), and NDBI (built-up areas). Indices normalize band ratios to reduce illumination and atmospheric effects.
