Who runs this map
The link goes to a statewide map (OKMaps (Oklahoma Office of Geographic Information) - Statewide Parcels layer). It shows parcels for Cimarron County along with the rest of Oklahoma. Because a state agency compiles this layer from local data, check with the Cimarron County assessor or recorder before relying on a recent change. As of our October 2026 test, anyone could open it without signing in or paying.
Searching for a parcel, step by step
- Open the statewide viewer in a new tab and move the map to Cimarron County (around Boise City).
- Nothing parcel-related shows at first. Add it through Explore > Land Parcels > Statewide Parcels, then click the green +.
- Zoom in closely; at wide views the parcel layer stays blank.
- Click a parcel to see its record, and keep the parcel ID handy for later searches with the county assessor or county clerk.
If an address search comes up empty, try the parcel number from a tax bill or deed instead, or click the lot on the map.

Before you rely on the lines
Keep in mind that a GIS parcel layer is a tax map, not a survey. For exact boundaries, look at the recorded deed and plat or hire a licensed land surveyor.
