Survey flying for the collaborative BGS and World Geoscience Corporation Ltd (WGC) high resolution geophysical and environmental survey was completed in early September 1998.

The data comprise multi-channel gamma ray spectrometer, magnetometer and dual frequency VLF-EM.

Flight line spacing was 400 m with tie lines at 1200 m and the total area surveyed is some 14 000 km2. Flight-line orientations are W–E over the western survey area, SW–NE over the eastern area.

Ground clearance was maintained at 90 m in rural areas, increasing to about 240 m in built-up zones.
