Collecting Data

If you get a Velocity near 0.300 m/ns, this could be an Air Wave response (the hyperbola
is from an object on the surface, NOT in the subsurface) and you should calibrate using
a different hyperbola.
7.1.9 Interpretations (Interps)
Short for field interpretation, Interps are used to mark subsurface features. Seven colors are
available, which allow you to designate different types of subsurface objects.
During collection, back-up or when reviewing a collected line, you can touch anywhere on the
screen to add an Interpretation (Figure 7-18). This appears as a dot of the current Interp color.
To change the color, press the
Interp button to see a selection of colors and to select a new
one (Figure 7-19).
To remove an Interp, ensure the same color is currently active and simply touch the Interp to
delete it.
These field interpretations get exported with the data as a .CSV file, which show the positional
information of all interps. They can be used to check if a feature is linear (in Map View or in
Google Earth
TM
), but usually only if the more accurate external GPS is used.
