| GPR (ground penetrating radar) Is a method of | | | | multiple, measured passes over the ground being |
| locating underground utilities and other buried | | | | surveyed. GPR equipment transmits high frequency |
| systems. This system is used often to create a map | | | | radar sound waves through the surface, penetrating |
