Subsurface imaging is a research area focused on the non-invasive mapping and visualization of geological and man-made structures beneath the Earth's surface. This includes the use of various geophysical techniques such as ground-penetrating radar, seismic imaging, electrical resistivity tomography, and magnetic surveys to create detailed images of the subsurface characteristics and features. Subsurface imaging is essential for applications in geology, environmental monitoring, archaeology, civil engineering, and resource exploration. It provides valuable insights into the underground environment and helps to identify potential hazards, locate buried objects, and assess the health of underground infrastructure.
