In the Spotlights: Geotechnical Exchange Format

April 16th, 2011

For geotechnical in-situ investigation the cone penetration test has been used world-wide. Based on the results of this type of soil investigation insight in the build-up and the bearing capacity of the subsoil will be gathered.

Traditionally the results of cone penetration tests are available in a digital form according to a specific format. This proved to be far from ideal. The variation in formats caused for a continuous need for different conversion programmes. It is for this reason that in 1999 the Geotechnical Exchange Format (or GEF for short) was introduced.
