Our software

VsSurf — from field QA to final report.

1D · Site class

VsSurf 1dS Software

Real-time data QA in the field, ensuring you collect the best possible results. Generate 1D S-wave depth-velocity profiles using both passive and active seismic sources — commonly used to assess site class (Vs100/30) and determine subsurface layer depths.

Reads SEGY and SEG2 file formats
Automatically generates 1D reports
