6.9 Creating a Test Line for Data Quality
One of the best ways of detecting problems with the GPR system is, shortly after receiving the system and
getting comfortable with its operation, to collect a line of data at a convenient, easily accessible location.
The line does not have to be too long but 100 - 200 traces is a good guide. This data line should be saved
electronically and perhaps plotted out on paper and dated. The test line could be collected say, every 6
months and, by reviewing the previous data, system problems can be detected early. As well, if there is a
suspected problem with the system, this test line could be collected and compared with earlier tests.
6.10 Adding GPS for Positioning

tioned near the mid-point of the GPR antennas.
