Near-Surface Geophysics
Select only branches supported by the supplied data. This is a single-agent workflow; companion skills are optional references, and a missing GPR or MT dataset does not prevent an ERT-only interpretation.
Input-dependent routes
| Input | Start with | Required checks before interpretation |
|---|---|---|
| GPR traces and acquisition geometry | gprpy |
Trace order/spacing, sample-time units, time zero, antenna offsets and an independently supported velocity model |
| ERT electrode geometry and measurements | pygimli |
Electrode indexing, measured quantities, geometric factors, uncertainty/reciprocals and topography |
| MT transfer functions or EDI files | mtpy |
Frequency coverage, impedance units and convention, rotations, tensor components and uncertainty |
| Multiple methods with compatible survey support | Process each branch independently, then compare | Common CRS/vertical reference, resolution, uncertainty and acquisition timing |
If only an image is available, state which quantitative operations require raw data or survey metadata. Do not infer a complete inversion dataset from colours or an unlabelled axis. Check package version and file-reader support before choosing a library-specific implementation.
