•
import from all well known GPR-formats like GSSI, MALA, Sensors&Software, IDS, UTSI, 3D-Radar, SEG2, SEGY and other non-standard formats
•
Building a 3D-dataset either from parallel equidistant 2D-lines or from freely distributed data inlcduing full GPS integration using a spatial interpolation scheme.
•
processing includes all necessary filter and edit functions starting from simple bandpassfilters up to complex Finite Difference migration. Special 3D-algorithms are available.
•
The 3D-data may be interpreted within the scroll, windows or 3D-cube mode. A 3-dimensional picking is included.
•
import from all well known GPR-formats like GSSI, MALA, IDS, UTSI, Sensors&Software,  SEG2, SEGY and other non-standard formats
•
Different methos for entering an arbitrary 2D geometry, e.g. crosshole data.
•
processing includes all necessary filter and edit functions.
•
Picking of first arrivals - manual, automatic or semi-automatic, ASCII-conversion of the picks
•
tomographic inversion of transmission traveltime data (2D straight and curved rays, 3D straight rays)
•
import from all well known GPR-formats like GSSI, MALA, Sensors&Software, IDS, UTSI, Zond, SEG2, SEGY and other non-standard formats
•
processing includes all necessary filter and edit functions starting from simple bandpassfilters up to complex Finite Difference migration. Also special algorithms for the different GPR-datatypes are included. Processing may be done on single profiles as well as on a set of profiles as a sequence processing.
•
Many different 2D-data interpretation tools are incorporated. Diffraction hyperbolas may be interpreted as well as single reflectors resulting in a so called layershow.
•
forward modelling for simulating the electromagnetic wave propagation in a 2-dimensional medium using a Finite Difference scheme enabling you for example to optimize your survey design in front of a measurement
•
CMP- or moveout-data are processed within the CMP-analysis menu which allows an interactive determination of the velocity distribution using different methods (e.g. semblance analysis).
