How the catalog is organized

Survey methods grouped by how they measure the ground, supported by geological, geohazard, and hydrogeological services.

Subsurface survey methods are grouped by how they measure the ground — electrical, electromagnetic, seismic, acoustic, magnetic, gravity, radiometric, thermal, remote sensing, and monitoring. Geological, geohazard, hydrogeological, and integrated application services support interpretation and project decisions but do not replace the measurements themselves.

Decision support

We integrate geophysical data with geological, hydrogeological, geotechnical, and project information so engineers and decision-makers can act with confidence before drilling.
