Spatial Distribution of Lufeng Dinosaur Valley Outcrops Based on the GF‐5 Hyperspectral OS–SPA–SVM Model

Journal of Spectroscopy, Volume 2025, Issue 1, 2025.
This study presents a novel approach to identifying the spatial distribution of geological outcrops using remote sensing, with the Lufeng Dinosaur Valley in China as the focal area. We integrate GF‐5 hyperspectral imagery with the automated morphological endmember extraction–pure pixel index (AMEE–PPI) algorithm to improve endmember extraction accuracy.

Multi‐Scale Soil Salinization Dynamics From Global to Pore Scale: A Review

Reviews of Geophysics, Volume 62, Issue 4, December 2024.
Abstract Soil salinization refers to the accumulation of water‐soluble salts in the upper part of the soil profile. Excessive levels of soil salinity affects crop production, soil health, and ecosystem functioning. This phenomenon threatens agriculture, food security, soil stability, and fertility leading to land degradation and loss of essential soil ...
