Ground penetrating radar (GPR) has revolutionized archaeological investigation, providing a non-invasive method to detect buried structures and artifacts. By emitting electromagnetic waves into the ground, GPR devices create images of subsurface features based on the reflected signals. These representations can reveal a wealth of information about past human activity, including habitats, cemeteries, and treasures. GPR is particularly useful for exploring areas where excavation would be destructive or impractical. Archaeologists can use GPR to plan excavations, assess the presence of potential sites, and map the distribution of buried features.
- Furthermore, GPR can be used to study the stratigraphy and soil composition of archaeological sites, providing valuable context for understanding past environmental conditions.
