G.L.O. Survey Field Notes, Digitized & Geo-Located

The same plats and field notes the BLM uses — searchable by township. OCR any field note page, map every survey call on the PLSS grid, then step into Street View and walk the same lines the original surveyors did — the ravines, creeks, and roads they described in the 1800s are often still there today.

How It Works

  1. Upload Field Notes

    Scan a page of handwritten GLO field notes and upload the image.

  2. OCR & Parse

    AI reads the handwriting and extracts survey calls with bearings, distances, and descriptions.

  3. Map, Walk & Export

    Survey calls are placed on an interactive map. Open Street View at any call to walk the surveyor's line, then export to KML, CSV, or PDF.

  • Corner Monument Street View

    Where Google Street View imagery exists near a PLSS corner, open an interactive panorama and pan to find corner posts, rebar caps, and survey disks on the ground. Imagery history going back years is included where available.
