Montana's Professional Engineers and Land Surveyors Board publishes an official PLSS Corner Record form. Surveyors document corner restoration evidence and file with the county clerk and recorder.
Filing Requirements
Public-land corner evidence is documented on the Board's PLSS Corner Record form and recorded with the county clerk and recorder. Perpetuation of corners follows the statutory land-survey requirements.
Street View Coverage
Of the 4,174 PLSS townships in Montana, 2,672 (64%) contain usable Google Street View imagery — meaning a surveyor can pull up the road camera view of a monument before ever leaving the office. Coverage skews toward roads and populated areas; monuments in remote rural sections are less likely to have a nearby capture.
| Metric | Value |
|---|---|
| Total PLSS townships | 4,174 |
| Townships with Street View | 2,672 |
| Coverage rate | 64% |
| Capture depth | Up to 20 years of history |
Corner-Plot Workflow
Upload a Montana 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.
