Field Spectroscopy
Basic Outline:
- Field spectroscopy relates to the measurement of the optical characteristics of a surface and provides quantitative measurements of radiance, irradiance, reflectance or transmission
- Analysis of specific areas of the spectral data can infer properties of the sample material, and various indices exist to quantify various parameters (e.g. NDVI)
- Portable field spectrometers can be used to quantify the chlorophyll a content in sediment surface over a large area.
