TellusSW airborne geophysical data WMS

BGS Technologies — Web map services

The TellusSW project acquired airborne geophysical data for the county of Cornwall and parts of Devon and Somerset during the second half of 2013. 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 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. The survey provided 60nbsp;323 line kilometres of data.
