Course Module: PF 129 – Culture-editing of Aeromagnetic Data

$35.00

High-amplitude, short-wavelength culture-related magnetic anomalies can adversely impact the processing and interpretation of aeromagnetic surveys. Since cultural features (man-made objects) are surface or near-surface, the problem is especially acute for modern HRAM (high resolution) surveys flown with low terrain clearance and close line spacing. Because of the low terrain clearance, the sensor-source separation is relatively short and the signal fall-off (inverse square or inverse cube) from a monopole/dipole-type culture source is unfavorably low. That means undesirable anomalies (magnetic noise) remain strong.

Learning Objectives

After completing this module, you will:

  • Understand the meaning of culture-generated anomalies and “culture-editing” (or “de-culturing”)
  • Know when and why to do culture-editing of aeromagnetic data
  • Understand some of the pitfalls of the culture-editing process
  • Understand how culture-editing will improve the quality of your magnetic data base and lead to more accurate interpretations
  • Be able to better relate this subject with Modules PF 115, 118, 119 and 126
