NIRS and Chemometrics Offer Insights Into Earth’s Surface

Facebook Twitter LinkedIn Email Comments

Ground-based NIR reflectance measurements are collected to develop calibrations that are later applied to hyperspectral data, offering the means to extract quantitative information about the Earth’s surface.

BRIAN CURTISS, ASD INC.

When applied to hyperspectral remote sensing images, the techniques of near-IR spectroscopy (NIRS) and multivariate chemometric calibrations, such as partial least squares regression, enable quantitative mapping of the properties of Earth’s surface. NIRS techniques and chemometrics have been...Read full article
