Midwest & Plains
Iowa law requires a section-corner certificate documenting the restoration of PLSS corners be filed with the county recorder (and county auditor). A corner certificate describes the monument, accessories, and ties.
Filing Requirements
When a public-land corner is found or restored, a corner certificate describing the monument, accessories, and ties is prepared and filed with the county recorder.

Corner-Plot Workflow
Upload a Iowa Corner Record PDF. Corner-Plot reads the form with OCR — extracting the surveyor name, township-range-section, monument description, and every bearing and distance tie. The corner is geo-located automatically across the PLSS grid, assigning a GCDB-standard 21-character Point ID and a confidence rating of High, Medium, or Low.
When the monument sits at or near a roadway, Corner-Plot brings up Google Street View with its full capture history — up to 20 years. AI analyzes each date and returns a structured monument-condition verdict. A printable field prep report covers the resolved coordinate, aerial tie overlay, monument classification history, and original GLO field notes.
