G-MAG

Geospatial Automation & Inference Analysis

Magnetic Data Processing & Interpretation Workspace

Process field magnetic survey data, run corrections, generate residual maps, visualise outputs, and interpret results in one unified workspace.

G-MAG Workspace

Move from uploaded magnetic survey data to clean, decision-ready outputs in one focused workspace. G-MAG brings setup, correction design, interpretation-ready processing, map review, and deliverable packaging together with a clearer operational flow and less switching between tools.

Platform

Core capabilities

Aurora AI

Get clear, plain-language guidance about your survey setup, processing choices, outputs, and deliverables.

Corrections

Apply diurnal correction, IGRF removal, and fixed regional/residual separation to condition your magnetic data.

Residual mapping

Review line profiles and supported residual maps from the uploaded survey data and fixed regional/residual workflow.

Interactive visualisation

Review your results through map overlays, profile views, and interpretation-focused summaries in a cleaner visual workspace.

Multi-format export

Deliver client-ready PDF reports, CSV bundles, and map image packages directly from the same project workflow.

End-to-end workflow

From raw survey CSV to final deliverable - everything happens in one place, no specialist software needed.

Analysis Configuration

Configure corrections and derived magnetic outputs for this task.

A - Processing / Corrections

Corrections are applied before regional/residual separation.

✓

Diurnal correction

Removes daily geomagnetic drift using base station readings where available.

✓

IGRF removal

Subtract International Geomagnetic Reference Field station-by-station from coordinates and survey date. Requires survey date.

Date source

Survey date

Computed station-wise from coordinates and survey date. Elevation uses mapped elevation, reference elevation, or a documented 0 m default with warning.

B - Regional / Residual Output

Generate the regional and residual magnetic fields from DCR using the fixed station-trend workflow.
