SEMO GIS is an assessor inventory tool, not a survey
Iron County's assessor points property users to SEMO GIS, while warning that it is for tax inventory and not for survey purposes.
Ironton parcel research can start with a map, but the map is not the boundary. Iron County’s Assessor discovers, lists, and values tangible real and personal property for tax purposes. The linked SEMO GIS layer helps users inventory parcels and assessment information, not settle lines on the ground.
That difference saves trouble in the St. Francois Mountains, where a parcel can look more certain on a screen than it is on site. The GIS can help a buyer find a parcel, compare tax details, and frame a better question for the Assessor. It should not replace a survey or decide a boundary dispute.
Use the Assessor and GIS for the tax-record layer. Use the Recorder for deeds, legal descriptions, or ownership-history questions. Use professional survey guidance when the question is where the line actually runs.
