Abstract
En 中文
• Multispectral slopes and angles of Sentinel-2 MSI were devised to estimate maize CRC. • We proposed spectral shape indices to improve CRC retrieval accuracy. • Combinations of tillage indices and spectral shape indicators can enhance CRC retrieval accuracy. • Spectral shape indicators were less affected by soil background and crop moisture.
