airbornegeo

🚀 Getting started

  • Overview
  • Install
  • Quickstart
  • Citing AirborneGeo

🛩ī¸ Initial processing

  • 1. Reproject data
  • 2. Change samping frequency
  • 3. Split survey data into lines
  • 4. Along track distance

🎚ī¸ Levelling

  • 1. Levelling to a grid
  • 2. Find survey intersections
  • 3. Cross-over errors
  • 4. Using equivalent sources for cross-over errors
  • 5. Tie line levelling
  • 6. Iterative tie line levelling
  • 7. Alternating iterative tie line levelling
  • 8. Assessing levelling results

Processing

  • 1. Filtering data in 1D
  • 2. Eotvos Correction
