Calculation results of mean difference in the scale of the predicted cavity according to the soil depth of the identified cavity.
| Average soil depth of the identified cavity [soil depth range] (m) | Difference in soil depth (m) | Difference in longitudinal section (m) | Difference in cross section (m) | Minimum | Maximum | Mean | Minimum | Maximum | Mean | Minimum | Maximum | Mean |
| 0.23 [0.11∼0.30] | −0.07 | 0.01 | −0.02 | 0.00 | 0.35 | 0.17 | 0.00 | 0.40 | 0.25 | 0.37 [0.35∼0.40] | −0.05 | 0.00 | −0.02 | 0.10 | 0.30 | 0.20 | 0.10 | 0.60 | 0.28 | 0.47 [0.44∼0.51] | −0.09 | −0.02 | −0.06 | 0.20 | 0.60 | 0.40 | 0.20 | 0.40 | 0.28 |
