EM4Soil is a software dedicated to electromagnetic (EM) data inversion. It has been designed for EM data acquired by multisensors or multifrequency EM devices such as DUALEM, Geonics (EM31, EM38, EM34, ...), GEM e GSSI.

EM4Soil uses a 1D laterally constrained inversion algorithm for the reconstruction of Quasi-2D models and 1D spatially constrained for Quasi-3D modelling.

Geostudi Astier is the EM4SOIL software representative in Europe.

Technical specifications

Supported OS

Microsoft® Windows XP, 7, 8,10.



  • Data pre-processing (filtering, decimation, data quality control, sensors correction, Latitudine/Longitudine to UTM coordinate coorection, etc..).
  • Inversion by means of linear and non-linear approaches (1D inversion for EM soundings, 1D laterally constrained inversion for Quasi-2D from profiles, 1D spatially constrained inversion for Quasi-3D models from parallel profiles).
  • Data map visualization with section extraction.
  • Visualization of inverted model and possibility to generate vertical and horizontal slices.
  • Export of inverted model as .xyz format for data display and managing by external tools (geostatistics,...).
