Time Series Data

Inspect recordings, check sensor calibrations and review station quality before processing.

Temporary storage · 30 minutes

For security reasons, uploaded recordings and calibrations are held temporarily in a private Google Cloud Storage bucket and expire after 30 minutes of inactivity. Browser previews are also cleared. Keep your original files; raw data is not included in saved projects.

Station inspection

Applied sensor responses

Exact serials are matched first. If none match, IDs and filenames are compared using numbers only; these fallback matches are flagged for you to check. Missing or ambiguous calibrations require a selection.

Metronix: amplitude in V/nT and phase in degrees. Phoenix: Column C trim curves; physical scaling requires TBL gains and sensor normalisation. Raw and PSD previews remain in recorded units.

Job

A Job captures one version of Data QC, Earth and Settings. Every execution gets a new Job ID.

This name prefixes cloud runs, model snapshots and exports, so each result stays associated with its survey.

Data input help — EDI, PLT, ModEM, WSINV and CSV

Upload one or more Ionos PLT, SEG EDI, ModEM (.dat) or WSINV (.data) native data files. ModEM accepts complex impedance, rho/phase and tipper blocks with declared units and Fourier sign; use north/east orientation (0°). WSINV accepts full tensors (8 values), applies error maps and reads local station coordinates. WSINV station IDs are generated from the filename and station order. Set the local origin below for cloud runs. Local offsets use a tangent-plane approximation; for large surveys supply surveyed latitude/longitude via CSV. PLT response blocks use apparent resistivity in Ωm and phase in degrees. Impedance blocks use mV/km/nT. Station IDs, coordinates and uncertainties are read from the file.

CSV columns: station,frequency,component,rho,phase. Optional: rho_error,phase_error,lat,lon,elevation,x,y,rejected. Frequency is Hz. Missing uncertainties default to 5% resistivity and 2° phase. Unsupported PLT layouts must be converted to EDI or CSV.

Geographic origin for local station coordinates

Set the surveyed latitude/longitude of local x = 0, y = 0. X is easting, Y is northing, in metres. Only stations missing geographic coordinates are updated. This local approximation is intended for compact surveys.

QC health: green = healthy, amber = review, red = needs attention. Score combines retention (35%), frequency count (25%), frequency span (15%), uncertainty (15%) and coordinates (10%). It is a screening aid; inspect curves before inversion.

Buy compute tokens

Local 1D runs and remote inversions currently use no tokens. Compute pricing is planned for a future release.

Checking whether top-ups are available…

AUD

Whole units of currency, before tax — this is what you are spending, not a number of tokens. How many compute tokens it buys, and the total including tax, are on the ledger below.

You will be sent to PayPal to pay, by PayPal balance or by credit or debit card — a PayPal account is not required to pay by card. Compute tokens are added to your account only after PayPal confirms the payment to Mineralis; tax is collected by PayPal and buys no tokens.

Company and tax details for your invoice — optional

Fill these in only if your invoice has to be made out to a company. They are copied onto each invoice as it is issued, and change nothing about what is charged or what tax applies.

Top-ups are charged in AUD.
