Data

Description

This dataset comprises Sentinel‑2 imagery acquired in 2016, 2020, and 2025, together with corresponding field‑measured soil salinity samples. A suite of spectral indices was calculated from the image bands, and a four‑dimensional feature space was subsequently constructed by integrating these indices with the measured salinity data. Based on this feature space, the salinization inversion analysis was performed using the established model.
