Embodiment Construction
[0034] Below in conjunction with specific examples, further illustrate the present invention, the examples are implemented under the premise of the technical solutions of the present invention, it should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0035] This embodiment discloses a forest interannual phenology monitoring method based on multi-source remote sensing, the method flow chart is as follows figure 1Shown: First, all available Landsat and Sentinel-2 images with cloud cover below 80% are collected, and then the integration method of Landsat and Sentinel-2 is modified to improve the spatial and spectral matching of different sensors. Then, a modified continuous change detection and classification (MCCDC) model was used to generate a daily vegetation index curve with a spatial resolution of 30m. Finally, based on the daily synthetic images, the logistic regression ...
