The BGS and World Geoscience Corporation Ltd (WGC) collaborated on survey flying for the high-resolution geophysical and environmental survey, which was completed in 1998.

The data comprises multichannel gamma ray spectrometer, magnetometer and dual-frequency VLF-EM. Flight-line spacing was 400 m with tie lines at 1200 m. The total area surveyed was some 14 000 km2. Flight-line orientations were west to east over the western survey area and south-west to north-east over the eastern area. Ground clearance was maintained at 90 m in rural areas, increasing to about 240 m in built-up zones.
