The TellusSW project acquired airborne geophysical for the counties of Cornwall and parts of Devon and Somerset. The maps of the geophysical data and their derivatives are provided to facilitate spatial comparison with, and modelling of, the soil, geological and environmental aspects of the data.

The data can be downloaded from the TellusSW project website.

The TellusSW project acquired airborne geophysical data 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 200 m (N-S) line separations at a mean elevation of 91 m. Encompassing the counties of Cornwall and parts of Devon and Somerset, the survey provided 60,323 line-km of data. Maps of the geophysical data and their derivatives are provided to facilitate spatial modelling of the soil, geological and environmental aspects of the data.
