3D VISUALIZATION AND ANALYSIS
In cavity data:
Arti cially created underground cavities such as tunnels, rooms, and tombs are shown in blue on the
graph. If there is any collapse or soil lling in the underground cavity, the cavity data will appear in light
blue, turquoise, and light green.
If you're looking for a structure with a di erent shape, the blue area in the graph should match this shape.
For example, if you're looking for a tomb, it should have a rectangular shape and be the size of a tomb.
Tunnel
ere should be at least a 15-unit di erence between the ground shown in green and the cavity
shown in blue on the graph.
For example, if the ground level is 150, the cavity data should have a value between 135 and 130.
If there is only a small di erence of a few units, this data represents gaps created by stones or
surface soil variations.

Depth Analysis:
You can measure the estimated depth calculations of the data you have
obtained using di erent modes.
With the "Depth Analysis"function, you can view the signal values
corresponding to each square in the data, and by selecting the soil type, you
can see the point-speci c depth information. When you tap on the signal
square you want to evaluate, you will see the values change in the window
that opens at the bo om.
e rst value you see is "Soil," which indicates the ground level.
To view the total depth of the scanning area, tap on the "General Depth"
option. In the window that opens,
you can move the bar to lower or raise the depth line.
