About GPRbase

Our mission

GPRbase was created to meet a simple need: providing easy access to quality GPR data for training and research, and to test data before renting or purchasing equipment.

Too often, users lack real data to practise radargram interpretation. GPRbase fills that gap: 30 raw, documented field datasets covering reinforced concrete, buried utilities, geotechnics, pavements, built heritage and geosciences.

Access costs nothing. The data is published under Creative Commons BY-NC-SA 4.0: free to reuse for teaching and research, with attribution, but not for commercial purposes without separate authorisation. We say free rather than open, because that restriction exists and we would rather state it.

Note: GPRbase only provides data from GSSI antennas. Website: www.geophysical.com GSSI

Who are we?

GPRbase is an initiative by MDS - Le Matériel de Sondage, a distributor and trainer specialized in non-destructive testing and detection equipment.

Drawing on our experience in GPR training, we identified the need for access to varied and documented data to improve training quality.

How does it work?

GPRbase collects and makes available GPR datasets from various sources:

• Data acquired during our training sessions and demonstrations
• Community contributions (operators, researchers, trainers)
• Partnerships with laboratories and universities

Each dataset is documented with essential metadata (equipment, context, what's visible) to facilitate learning.

Contribute

GPRbase is a collaborative initiative. If you have data you'd like to share, submit it to us! Every contribution enriches the database and helps the community. Submit Data

Join the GPR data community

GPRbase publishes the data; the conversation happens elsewhere. On r/GPRdatasets you can discuss GPR datasets, share resources, request specific data and connect with researchers, professionals and developers.

A second paper, on the use of the datasets for training in concrete non-destructive testing, appeared in the e-Journal of Nondestructive Testing. It describes twelve concrete datasets, six training exercises and the metadata declared for each, including ground truth:
