Parcel Map and GIS Boundary Limitations

Use county GIS maps correctly and understand why parcel lines, acreage, addresses and aerial imagery may not prove a legal boundary.

Direct answer: A county parcel map is a tax-administration and navigation tool. It is not a substitute for a recorded plat, deed description or licensed boundary survey.

What parcel maps are good for

GIS maps help locate parcels, identify account numbers, view nearby parcels, compare aerial imagery, find taxing jurisdictions and open linked property cards. They are especially useful when an address search fails.

What they do not prove

  • Exact legal boundary location
  • Ownership of fences, driveways or improvements
  • Legal access
  • Current easement rights
  • Survey-grade acreage
  • Buildable area or zoning approval

Why the line can look wrong

Parcel geometry can be generalized, shifted relative to aerial imagery, based on older plats, or updated on a different schedule than assessment ownership data. Aerial photographs can also be orthorectified imperfectly.

Frequently asked questions

Can I resolve a fence dispute with the GIS map?

No. Use recorded documents and a licensed surveyor. The GIS line alone is not boundary evidence.

Why does the parcel map show the neighbor’s address?

The situs address, mailing address, map label and building point may come from different datasets. Open the property card and confirm the parcel identifier.

Can I measure acreage from the map?

You can obtain a rough planning measurement, but use the deed, plat or survey for a legal or purchase decision.
