Tracking mining with multispectral satellite imagery (agnescameron.info)
This is a writeup of research into using satellite imagery to track mining operations, funded as part of Bellingcat’s 2024 Technical Writing Fellowship, and is a more in-depth version of a short guide published on their online platform. The accompanying Multispectral Satellite Imagery Explorer tool is available here. This guide is intended as an overview of my research, and a starting point for these techniques.
