Basic UAV data processing:
- Read raw data (CSV, TXT, BIN)
- Altitude from barometric pressure and DEM (if no RTK GPS)
- Map coordinates (UTM or ETRS-TM35FIN)
- Fluxgate sensor calibration
- Orientation correction
- Data visualization as maps and profiles and in 3D
- Base station correction
- Data cutting, joining and filtering
- Save data (UAV) and export data (XYZ)
Equivalent layer modelling (ELM):
- Numerical (least squares) inversion using a single-layer susceptibility model
- Total field and/or individual XYZ components
- Dataset leveling and trend removal (tie-line correction)
- Heading correction
- Compute magnetic field on an even grid at constant altitude
- Compute derivatives (1st vertical derivative, tilt and horizontal gradient)
- Downward continuation and reduction to pole
- Corrects flight height variations
- Micro-leveling
