Enhancing Estimation of Leaf Nitrogen Content in Ginkgo Saplings Using Wavelet-Based Indices Derived From UAV Hyperspectral Imagery
The estimation of leaf nitrogen content (LNC) is important for assessing the growth status of Ginkgo saplings. UAV hyperspectral imagery provides an effective data source for estimating LNC. However, canopy structural variation can affect hyperspectral signals. Although canopy scattering coefficient (CSC) correction ca...
