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, export a KML, and detect potentially fraudulent notes based on terrain and elevation.

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 & Export

   Survey calls are placed on an interactive map. Export to KML, CSV, or PDF.
