Gravity Surveys

• Scintrex CG-5 Autograv gravimeters
• Topographic leveling with differential or carrier phase GPS
• Laser rangefinder near-station terrain correction surveys
• Precision or regional surveys, with ample experience in rough topography
• Terrain corrections with customized digital terrain models
• Standard and specialized reductions and corrections (eg. Bullard-B, variable zone radii) including bathymetry corrections for lake ice surveys
• Boat supported sonar bathymetry
• 3D inversion and forward modeling
