Airborne geophysical data from the Tellus South West project

Dataset description

Airborne geophysical data acquired as part of the BGS-NERC TellusSW project ( during the second half of 2013. The survey comprised a high resolution magnetic/magnetic gradient survey combined with a multichannel (256 channel) radiometric survey. The survey was carried out using 200m (N-S) line separations at a mean elevation of 91m. Encompassing the counties of Cornwall and parts of Devon and Somerset, the survey provided 60,323 line-km of data. Digital data and derived (e.g. spatial derivatives) maps of the geophysical information are provided to facilitate spatial modelling of the soil, geological and environmental aspects of the data.


The data are delivered under the terms of the Open Government Licence, subject to the following acknowledgement accompanying the reproduced BGS materials: "Contains British Geological Survey materials copyright NERC [year]".
