摘要

Vegetation indices (VIs), which are combinations of various remote-sensing spectral bands, are widely used to study various biophysical properties. There are many articles introducing new VIs with the intention of minimizing factors such as soil background, canopy architecture, and row structure, while maximizing sensitivity to a specific biophysical characteristic such as the green leaf area index. Two VIs introduced in a previous study for the estimation of the biophysical characteristic green leaf area index are the modified chlorophyll absorption ratio index 2 (MCARI2) and modified triangular vegetation index 2 (MTVI2). This study and another study indicated that MTVI2 and MCARI2 gave identical results, but the mathematical similarity was not described in detail. Thus, future studies investigating the accuracy of Vis for estimating the biophysical characteristics need to examine either MCARI2 or MTVI2.
