Field Spectroscopy and NDVI

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.
