How Satellite Imagery Captures Mine Site Changes

Satellite imagery for mine monitoring relies on a combination of optical and radar sensors mounted on orbiting platforms. These satellites pass over thee same locations on a predictable schedule, capturing snapshots that can be compared across time. Thee core principles is exampliforward: by aligning images take at difative dates and analyzing differences in reflectance, geometry, or spectral signature, analysts cain quantimacy surface chances.
