Geophysical software

Product range


For more than 25 years, DELPH software suite has been extensively used by surveyors and geophysicists around the world, providing leading edge software and hardware solutions.

DELPH acquisition software is a unified data logging solution to safely monitor and record side-scan sonar, seismic and subbottom profiler data in a resolutely simplified user interface. It focuses on reliability and online QC.
DELPH interpretation software brings a new workflow to geophysical data processing and integration; it has the unique capability of handling vast amounts of data in a short time using batch processing while still providing the finest details. DELPH interpretation is the unbeatable solution when processing time is critical. From raw data to final deliverables, all data sonar, sub-bottom, magnetometer, bathymetric and geographical layers integrate in DELPH 3D geographic visualization for an advanced QC on a global survey scale. This also ensures the best possible geo-referencing and immediate compatibility with geographical information systems. With scrolling profiles no longer needed, you can directly access complete datasets, always geo-referenced.
