Interpretation of Raptor data, part 1 (Condor software)
In the previous note we briefly covered data collection and the most common processing steps. We concluded that if the raw data is of good quality, especially when it comes to positioning, the following processing can be swiftly done with modern software. That brings us to the most time-consuming step in managing 3D GPR data - interpretation. This stage is a real bottleneck and where good software can make a significant difference. In this note, we look at the simplest, but a reliable, way of interpreting Raptor data.
Top-views are probably the most common when it comes to interpreting 3D GPR data. However, they are not that useful for the precise picking of target depths. Instead, their strength lies in giving the user an overview and the perception of the target layouts. Having 3D data at hand provides us with the ability to view any 2D cut in that data volume. If those cuts are made properly, then picking a target in the 2D view, combined with views and picks in the top-view, makes the process more accurate.
