Delivery format

DINOloket users can obtain their requested cone penetration test data in the Geotechnical Exchange Format (GEF), a standard format for the digital exchange of cone penetration test data (in ASCII).

The recording of the metadata, such as the cone penetration test number, the coordinates and the performer of a cone penetration test, is standardised. The same standards also apply to the storing of the results.

More information about GEF and a description of the GEF format for cone penetration tests can be found at, under Dossiers/Grondonderzoek. Cone penetration test data can be visualised using the GEFPlotTool.
