Vegetation Spectra

Vegetation spectra capture the optical properties of plant materials — leaves, bark, flowers, and dried plant matter — across ultraviolet, visible, near-infrared, and mid-infrared wavelengths. These measurements reflect the biochemistry of living and dried tissue, including chlorophyll content, cellulose structure, water absorption, and lignin signatures.

Plant spectroscopy and vegetation NIR measurements are fundamental to remote sensing, precision agriculture, and ecological monitoring. Leaf reflectance spectra serve as ground truth for satellite-based vegetation indices like NDVI, while FTIR spectra of dried plant tissue support studies in wood science, paper manufacturing, and archaeological botany. Reference spectra for diverse species allow researchers to build classification models and detect stress markers in crops.

SpectralBench hosts vegetation reference spectra from the USGS Spectral Library. View interactive charts, examine measurement metadata, and download data in CSV or JCAMP-DX to integrate with your remote-sensing or laboratory workflows.
