smartTomo 2020.2 has been released

Version 2020.2 has been released and it introduces some visualization improvements. Now the dromocrons can be displayed in only two colors instead of the standard multicolor mode.
Exporting the profile from the screenshot has been improved. It is now possible to get a screenshot at a higher resolution than the screen resolution (if supported by the video card)
Screenshot capture is now also enabled for dromchrone display.

The 2-color dromchrone offers a better visualization of the differences between calculated and measured times.

Case study – Model of alluvial deposits at the foot of a slope


SmartTomo’s ability to process complex refraction tomographic profiles is tested using data computed on synthetic velocity models. The synthetic velocity model represents a geologic model sketched with the characteristics to be tested. The synthetic model is used to simulate a refraction seismic acquisition by recording arrival times at the geophone location. The recorded data will be used to perform tomographic processing in order to compare the tomographic result with the synthetic geological model (groundtruth).

Version 2020.1 released

We are pleased to announce the release of smartTomo 2020.1 which includes the bug fixes released so far as individual updates of the previous version.
This version does not introduce new features but more stability of use than ever before

smartTomo 2020.0 released

The SmartTomo 2020.0 version introduces new features and numerous bug fixes compared to previous versions. From this version SmartTomo becomes a full-featured software for refraction seismics by integrating both the tomographic processing with GRM method seismic refraction. Now within the software it is possible to perform refraction processing and display the refraction profile either separate or overlaid with the tomographic processing.

Seismic refraction profile elaborated with smartTomo using GRM procedure

In SmartTomo we give a lot of importance to the ability to display results without the need to use external software. The visualization of the tomographic profile is the means by which specialists interpret the results and therefore it is essential that it is versatile and clear. Version 2020.0 introduces the possibility to choose the size of the geophones display on the profile.
From this version it is possible to compose on screen the view to be exported and save it directly on file obtaining a true copy of the screen. This also allows the creation of focused details of the profile.

In addition SmartTomo from version 2020.0:

  • imports files in seg2, sgy and SU formats;
  • allows you to choose the density of the labels on the isolines avoiding overlapping;
  • export profile screenshots to get enlarged details of the tomographic section.

Results Testing

This version of smartTomo has been tested using a synthetic dataset available on the forum. It is a 3-layers profile with a slope in the deepest refractor.

Profile of the ground-truth model used to test smartTomo

The dataset has been analyzed with smartTomo obtaining the following profile:

Case study – Detection of a tunnel.

In this work, seismic refraction tomography (SRT) was performed to investigate the characteristics of the subsoil and to investigate the evidence of the presence of a tunnel used for the carrying of water.

The survey was carried out using 24 vertical geophones and performing a high number of vertical energizations both inside and outside the line, in order to have a good coverage by seismic rays throughout the section.

Case study: Evaluation of the depth of the rupture surface of a landslide

Following the rupture of an water pipeline, a landslide movement occurred in an area classified as highly susceptible to collapse. The event dislocated a retaining wall and created tension cracks in the ground. In order to define the geometry of the materials involved in the movement, a seismic survey was carried out using the technique of seismic refraction tomography and the MASW.

Download demo

The smartTomo demo version allows the users to perform tomographic processing on a preloaded dataset.
The dataset has been recorded on a landfill site where the limestone rock substrate deepens from right to left. The data has acquired by a 16-bit, 16-channel seismograph made by SARA Electronic Instruments . Six energisations were carried out which allowed to identify the geometry of the filling materials.
