GeoLayer  /  Borehole Log Digitiser

Extract SPT N-Values & RQD from Borehole Logs

SPT N-values and RQD (Rock Quality Designation) are buried in dense log columns and easy to mis-key. GeoLayer reads them straight from your borehole log PDFs — scanned, handwritten or digital — into a structured, editable table.

The test data, without the transcription

GeoLayer locates SPT N-values and RQD in the log layout the way an engineer reads it, then pulls them into clean rows alongside depth, strata and coordinates — ready to export.

Engineer-reviewed, not blindly trusted

Every value is reviewable and editable on screen before export, so your test data lands in a clean, defensible state instead of carrying transcription errors into analysis.

Frequently asked questions

Can GeoLayer extract SPT N-values from a scanned log?

Yes. GeoLayer is built for scanned, photographed and handwritten borehole logs and extracts SPT N-values, RQD, depth and strata into a structured table.
