A Globally Distributed Soil Spectral Library Visible Near Infrared Diffuse Reflectance Spectra World Agroforestry Centre (ICRAF)

Abstract

The need to maintain the health of the soil resource base as an imperative for sustainable development is increasingly being recognized. Science and technological developments in remote sensing are providing new opportunities for low cost and efficient applications for characterizing and monitoring the health of the soil resource base. We are pleased to introduce this spectral library of world soils, which will provide a valuable resource for research and applications for sensing soil quality both in the laboratory and from space. This product is a result of collaboration between ICRAF and ISRIC scientists and we encourage further development of this area of research.
