Sentinel-2 Multispectral Satellite Remote Sensing Retrieval of Soil Cu Content Changes at Different pH Levels
With the development of multispectral imaging technology, retrieving soil heavy metal content using multispectral remote sensing images has become possible.However, factors such as soil pH and spectral resolution affect the accuracy of model inversion, leading to low precision.In this study, 242 soil samples were collected from a typical area of th
