Stop tracing soundings by hand
An automated extraction engine that replaces a full day of manual CAD digitizing. It reads the depths straight out of the PDF — drawn as geometry, set as text, or as labelled contour lines — and returns easting, northing, depth and confidence per point.
* Timing is based on a single-page vectorized PDF with roughly 2,000 soundings.
Vector sounding PDFs only. Scanned raster images, flattened bitmaps, paper charts, and OCR/AI-read charts are not supported.
For Tender Estimation & Verification Only. Extracted datasets are not certified hydrographic products and must be verified by a licensed professional surveyor prior to field operations.

Sounding charts draw depth in a handful of ways. Here's what the engine reads.
Numeric, vector-drawn
Each depth is a real number placed as vector text over its mark — geometry, not pixels.
Numeric, as text labels
Depths placed as plain text annotations rather than marks anchored to the drawing's geometry — common on CAD exports and typed overlays.
Contour / isobath lines
Depth drawn as labelled contour lines rather than individual soundings — read into points along each contour, at its depth.
