Wyoming GIS Maps by County: The Parcel Viewer Each Uses

Which parcel map software each Wyoming county uses (23 of 23 verified), how to search the common viewers, and a link to every official map.

Looking for Wyoming county GIS maps? Wyoming has 23 counties, and their official parcel maps do not all run on the same software. Knowing which viewer a county uses tells you what the search box expects and where the parcel details are.

If you look up land in more than one Wyoming county, you will notice the parcel maps don't match. That is because each office chooses its own software. Below, all 23 Wyoming entries in our directory are listed with the viewer each one uses, plus tips for the most common types.

How to search the most common viewers in Wyoming

TerraGIS (14 entries, e.g. Albany County, Big Horn County, Carbon County)

  1. Accept any disclaimer, then use the search tool to find a street address, owner or parcel ID.
  2. Click a parcel to view its attributes.
  3. Use the layer or basemap controls to add aerials and other layers where the county provides them.

Beacon (Schneider Geospatial) (4 entries, e.g. Campbell County, Fremont County, Goshen County)

  1. Open Beacon, the Schneider Geospatial parcel platform this county uses. Accept the usage terms if asked.
  2. Search by address, owner or parcel number, or zoom in and click a lot.
  3. From a parcel's pop-up, open the full record to see values, sales or building data where the county shares them.
  4. Switch layers on or off to compare parcels with aerials, zoning or other overlays.

ArcGIS Experience Builder (2 entries, e.g. Crook County, Natrona County)

  1. Open the link. This viewer is an ArcGIS Experience Builder app, so its layout is custom to the publisher.
  2. Look for a search box or search widget and type in a street address or parcel ID.
  3. Click a parcel to see its details in a pop-up or side panel.
  4. Check the toolbar for a layer list or basemap switcher if you want aerials or other layers.

Before you rely on what you find

Online parcel lines are drawn for tax mapping, not surveys, so they can sit a few feet off the real boundary. For anything legal, such as a fence, a sale or a dispute, use the recorded deed and a licensed surveyor. To check flood zones, soils or wetlands for a spot you found, open it on the Platbookmapper Land Map, which pulls FEMA, USDA and U.S. Fish & Wildlife layers.
