- .interpolated.srf_prfl.dat is ASCII file like “.srf_prfl.dat”. This file is
generated only from continuous measurements (both manual and GPS).
The positions of measured points without primary position information
(data measured between length marks or between valid GPS data
positions) are interpolated between data with known positions.
- .res2D.dat is ASCII file allowing compiling data using Res2DInv software.
This file is generated only from CMD-Explorer / MiniExplorer
measurements. Measured conductivities are converted to resistivities as
they would be measured by geoelectrical instrument using Wenner-
Schlumberger array. For manual measurement, each measured profile is
stored in individual file. The second and other files are labeled
“.res2D_xNN”, where NN is the order of the profile. For GPS
measurement, the “Track” (distance from the beginning) is used as
position on single profile. To see the corresponding GPS data and the
Track please export also “.srf_prfl.dat” file. The lowest step of the
position is 0.5 m, so each position is rounded to 0.5 m. Duplicated values
(several times measured the same position) are deleted. Because the
Res2DInv calculating is time and memory consuming it is recommended
to operate profiles shorter than 1000 m. The measurement must be done
along parallel profiles, bias profile is not convenient.

- .res3D.dat is ASCII file similar to “.res2D.dat”, which is importable into
Res3DInv software. This file uses alternate geoelectrical array Wenner-
Schlumberger array with 0.5 m electrode distance in the same way as
“.res2D.dat” file. The file can be generated only from manual
measurement, not from GPS measurement. For sustainable data size
several profiles shorter than 100 m is recommended. Duplicated values
(several times measured the same position) are deleted. The measurement
must be done along parallel profiles, bias profile is not convenient.
