Abstract Multitemporal spectrum data of wheat with high resolution have been processed using a digital derivation algorithm and their properties of red edge shifting toward long wavelenth have been extracted. Relationship between red edge shift and spectral resolution. growth period. chlorophyll content in leaf and coverage rate for wheat have been analysed. And then an optimal season to detect the properties of red edge shift have benn proposed,
