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 west–east over the western survey area, south-west–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.
