Air-FTG® vs. Ground Gravity

Example: Air-FTG® comparison with ground gravity

Ground Air-FTG
First vertical derivative of ground gravity data
Air-FTG® measured first vertical derivative (Tzz)


Ground gravity data
Integrated tensor data (Tz)
The Air-FTG® data compares well with the ground gravity. Some areas have limited ground gravity coverage, which reduces the resolution of the ground gravity as compared to Air-FTG®.
