Notes

Purpose
High-resolution gravity on regional/district scales is an important component of mineral and energy integrated pre-competitive approach to data collection and information to support new and ongoing industry exploration investment in Australia's resources. Such data is also invaluable for vertical positioning accuracy with industry and government agencies requiring vertical height surfaces to within 10 cm for advanced (often autonomous) operations, productivity efficiency, and safety.
