Airborne Quality Control

Airborne Quality Control provides essential tools for planning an airborne survey, and meeting basic tender specifications.

It includes flight path planning tools, the ability to monitor the survey progress, and streamlined quality control (QC) tools.

The Flight Path Planning creates a flight line plan tailored to the shape and size of the survey area. Boundary maps of the survey area can be imported from an AutoCAD DXF file or digitized as polygon files. Planning controls specify the direction, starting reference point, and distance between flight lines for the airborne survey area.

The QC statistical tool generates and prints a statistical report for meeting tender or operational specifications. A built-in mapping wizard automatically displays QC results.

Quality control functions provide the ability to perform tests for altitude deviation, flight path deviation, flight line separation, sample spacing, diurnal drift and magnetic noise.

Use Airborne Quality Control tools to:

  • Generate flight path map of planned survey.
  • Display survey statistics.
  • Display survey line distance.
  • Create intersection tables.
  • Perform altitude deviation QC test.
  • Perform flight path deviation QC test.
  • Perform flight line separation QC test.
  • Perform sample spacing QC test.
  • Perform diurnal drift QC test.
  • Perform magnetic noise QC test.
  • Map and print QC results

Geophysics Levelling

Geophysics Levelling incorporates 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, and includes a microlevelling toolkit.

Geophysics Levelling

Geophysical Levelling 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 Geophysics Levelling tools 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.
