GB/T 45725-2025 Visible to short-wave infrared spectral reflectance measurement of crops

Scope

This document describes the measurement conditions, preparation work, field canopy spectral reflectance measurement, leaf spectral reflectance measurement, spectral measurement data processing, and preparation of measurement reports and data transfer for the spectral reflectance of crops in the visible and shortwave infrared bands (350 nm to 2,500 nm) grown in natural field environments. This document is applicable to the remote sensing monitoring of crops grown in natural field environments and the construction of spectral libraries for canopy and leaf spectral reflectance in the visible and shortwave infrared bands (350 nm to 2,500 nm). The measurement of spectral reflectance in the visible and shortwave infrared bands (350 nm to 2,500 nm) of other crops' canopies, leaves, flowers, and fruits should be carried out in accordance with this document.
