Ground penetrating radar profiles are created by dragging a radio antenna and receiver across the ground. The antenna emits polarized electromagnetic waves downward that reflect on boundaries within the earth that separate rocks with different electrical conductivity or dielectric permittivity within the subsurface. The reflected wave is recorded by the antenna, which generates a two-way travel time. These data are processed to show the depth to multiple boundaries across the profile. The processing is similar to seismic reflection processing and the resulting profile also has a similar look but may show different boundaries. It is a particularly good method to image the very near-surface (upper 10 m).<\/SPAN><\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "summary": "This line feature class relates critical information about individual ground penetrating radar surveys so that researchers may quickly discern the quality of the data, including how the data was collected, what processing parameters were used, where the survey was located, and what the results of the survey were.
