The COGO Reader tool reads and extracts COGO dimensions from Deeds. Instead of manually entering COGO dimensions for hours, you can extract and review the COGO measurements in a matter of minutes.

COGO Reader is designed for US deeds that contain metes-and-bounds descriptions written in English.

This session covered:

  • How to read OCGO and create parcels
  • How to review the extracted dimensions and misclose
  • How to fix failed OCR to improve COGO extraction
  • How to use the traverse for deeds that were partially extracted
  • How to create a parcel fabric in 5 minutes and start using COGO Reader
  • Providing feedback
  • COGO Reader road map
  • Q&A

First two deeds I tried on the COGO Reader had multiple issues. Could not distinguish between connection lines and parcel lines, used metric bounds instead of the textually adjacent feet bounds, and not defaulting to the Long Chord bearing and distance for a non-tangent curve. Two deeds are attached.
