SPT & CPT Analysis

Interpret in-situ test data with every method, side by side.

Upload raw cone or SPT records. Atlaned classifies SBT zones, reconciles the layer model with your borehole record, and runs every applicable correlation in parallel — so the engineer compares methods instead of typing them.

  • Automatic SBT zone classification (Robertson 1990 / 2009)
  • 14 correlation methods for φ′, su, Dr, E, OCR
  • Outlier flagging with provenance back to source trace
  • Re-runs live as new traces upload from the field

Liquefaction Assessment

Check triggering and post-event hazard against the codes.

Triggering analyses on CPT and SPT, reduction factors, post-liquefaction settlement and lateral spread — referenced to the standards your reviewers expect to see cited.

  • Boulanger & Idriss (2014), Robertson (2009), NCEER
  • Site-specific PGA, M_w, water table inputs
  • Layer-by-layer FoS with depth plots
  • Post-liquefaction settlement (Zhang et al.)

Laboratory Tools

Turn lab data into deeper insights — typeset in your brand.

The standard suite, captured cleanly and rendered as reports indistinguishable from the ones your senior engineer drafts by hand. Logo, palette, signatory block — uploaded once, applied everywhere.

  • Atterberg, PSD, triaxial, oedometer, UCS, shear box
  • Per-sample audit trail back to the borehole
  • Branded PDF output with your firm’s template
  • AGS 4 export for downstream design packages

Cross-section Designer

Design, review, and present sections — populated from your boreholes.

Pick two points on the plan. Atlaned interpolates layers between the boreholes you crossed, projects laboratory and field results to depth, and gives you an editable section ready for design review.

  • Auto-interpolation between borehole layers
  • Water table and observation overlays
  • Editable strata polygons with snap-to-borehole
  • Vector export to AutoCAD Civil and PDF

Correlation Finder

Find, compare, and decide on correlations faster.

Run every applicable method against your layer’s measurements. Atlaned ranks them by statistical fit, shows residuals, and records the choice you adopt — so the design parameter is defensible, not anecdotal.

  • R², residuals, and confidence band per method
  • Adoption recorded with engineer and timestamp
  • Custom in-house correlations alongside published
  • Citations rendered into the factual report

Atlaned Inference

Generate insights across an entire archive of geodata.

Decades of investigations are trapped in scanned PDFs and one-off spreadsheets. Atlaned Inference reads the archive and returns structured records you can query, compare, and design from.

  • Cross-project search by stratum, depth, parameter
  • Parameter distributions across sites and time
  • Reviewer queue for low-confidence extractions
  • Source page surfaced beside every value

Borehole Extraction

Extract data from logs and reports without re-typing a thing.

Drag in factual reports, GEF traces, AGS exchanges, or scanned legacy logs. Atlaned reads layer descriptions, depths, SPT N-values, groundwater notes, and lab results into the project record.

  • PDF, scanned PDF, AGS, GEF, XLSX inputs
  • Layout-aware extraction with OCR fallback
  • Confidence scores per field and per layer
  • Round-trip back to AGS 4 with provenance

Document Understanding

Turn documents into usable data — not another PDF library.

Specs, factual reports, interpretative reports, correspondence. Atlaned reads the document, understands the structure, and surfaces the values, references, and decisions where they’re needed in the project.

  • Tables, figures, and inline values extracted together
  • Citation graph across reports and revisions
  • Question-answer over the project corpus
  • Reviewer trail for every value adopted
