GeoLayer / Borehole Log Digitiser

Digitise Handwritten & Scanned Borehole Logs

Field logs are rarely tidy PDFs. GeoLayer is built specifically for the messy reality — handwritten records, photographed field sheets and scanned documents — and turns them into structured, exportable geotechnical data.

Built for real-world field logs

Generic OCR chokes on borehole logs: rotated scans, faint handwriting, dense columns and shorthand. GeoLayer is trained on geotechnical logs, so it reads the layout the way an engineer does and pulls out the values that matter.

Reads handwritten field sheets, photos and scanned PDFs
Extracts depth, strata descriptions, SPT N-values, RQD and coordinates
Flags low-confidence values so you know exactly what to check
Exports to Excel, AGS4, gINT, OpenGround, CAD (DXF) and CSV

Review, don’t re-type

You stay in control: GeoLayer presents the extracted data with confidence flags, you correct anything that needs it, and then you export. It turns hours of transcription into a fast review.

Generic OCR vs GeoLayer on field logs

	Generic OCR	GeoLayer
Understands the log layout	No — returns raw text	Yes — reads it the way an engineer does
Handwriting & rotated scans	Often fails	Built for messy, real-world logs
Output	Unstructured text to clean up	Structured depth / strata / SPT / RQD, reviewable
Export	None	Excel, AGS4, CAD (DXF) and CSV

Frequently asked questions

Can AI really read handwritten borehole logs?

GeoLayer is built specifically for handwritten, photographed and scanned borehole logs. It extracts the data and flags any value it is unsure about so an engineer can confirm it before export.

What if a value is unclear in the scan?

Uncertain values are flagged with a confidence indicator. You can review and edit any field on screen before exporting.
