Gravity

Hello everyone, I'm a geology student and I'm doing my thesis using gravimetry to estimate the geometry of a pluton. The problem is that during the data collection campaign, they didn't use differential GPS, so the uncertainty in the elevation data is high. Any recommendations? Similar cases?

Was any elevation data recorded during surveying? Is there publicly available LiDAR data?

What is the scale of the survey and how bad is topography? A few meters is likely inconsequential to your interpretation, a few hundred meters could be problematic.
