ICRAF Spectral Library
Listed in NASA Earthdata CMR
ICRAF Spectral Library The ICRAF spectral library contains over 30,000 spectra (wavelength range of 350 to 2500 nm) of more than 12,000 soil samples, 168 sediment samples, 500 plant samples, and several manmade material samples and rock samples.
Description
Matching attribute data on physical and chemical properties are available for large numbers of soil and plant samples. Samples from more than 3000 sites in the Kenya Lake Victoria Basin are georeferenced to survey grade accuracy.
More specialized attribute data, not yet documented in the main database, are available for specific sets of samples. The library provides a valuable resource for testing new analytical approaches in soil spectroscopy and remote sensing applications. Data available are: 1) Soil library 2) Organic Resource Library Data Link: See Related URL Field This information obtained from the World Agroforestry Center web site: "worldagroforestrycentre.org/"
