Techniques originally developed for processing and manipulating satellite imagery, such as decorrelation stretch algorithms, are now actively being applied to uncover faint and hidden ancient artwork. The digital method allows researchers to distinguish pigments and historical markings that have severely degraded over time and are no longer visible to the naked eye.
By enhancing color contrasts and isolating spectral data, the software makes non-invasive archaeological research more accurate and accessible. This technology transfer highlights how computational tools built for space and Earth observation can provide significant utility across other fields of scientific study.
