Maurice Udung Etor asked:

What is GPR in Physics?

Answer:

GPR means Ground Penetrating RADAR

Ground penetrating radar locates almost anything underground. Ground penetrating radar makes an underground cross-sectional, two-dimensional image of the soils and subsurface features.

Multiple lines of data systematically collected over an area may be used to construct three-dimensional or tomographic images. Data may be presented as three-dimensional blocks, or as horizontal or vertical slices. Horizontal slices (known as “depth slices” or “time slices”) are essentially planview maps isolating specific depths.
