From now on, users are able to select and download a collection or survey of non-confidential 3D seismic data themselves via the NLOG map for free. This will increase the ease of use, save costs and eliminate the need for intervention by the Service Desk. Making such a substantial collection of 3D seismic data available in this way is unique in Europe and the world. The Geological Survey of the Netherlands, part of TNO, herewith makes a big leap forward with respect to open data in this field.
