The montaj Geophysical Levelling extension includes advanced tools for processing and enhancing airborne magnetic and other geophysical data. It provides a step-by-step methodology for accomplishing a variety of levelling and correction tasks.

A Microlevelling toolkit enables you to perform microlevelling corrections on line-based data.

With the Iterative Levelling option, you can optimize the identification and correction of errors in geophysical data. The Iterative Leveling option will repeat the process of levelling ties to flight lines, then flight lines to ties, until the process converges.

Use montaj Geophysics Levelling to:

  • Evaluate Data for Systematic Error and Noise.
  • Correct Systematic Errors in Geophysical Data (magnetic base station, lag, heading, and IGRF corrections).
  • Find and Edit Intersections (between any lines in a dataset).
  • Perform Statistical Levelling of Tie Lines (lines can either be regular survey lines and tie lines.
  • Perform Full and Careful Levelling of Survey Lines.
  • Perform microlevelling corrections on line-based data.
  • Remove any low amplitude component of flight line noise still remaining in airborne survey data after tie line levelling.
  • Minimize or remove different survey parameters, noise levels, or uncertainties at the grid edges, to create more seamless grid compilations and identify subtle geophysical anomalies.
