Notes for GIS users
Service name is year-specific - a new Wyoming_Parcels_for_<year> service appears each year under the same org (r0iJ85SKZ4zAzz3P), so check for a newer one annually. jurisdicti is the upper-case county name without spaces (LARAMIE, HOTSPRINGS, BIGHORN). accountno is NOT unique statewide (R0022885 matched 5 counties); filter by jurisdicti. locationad may contain double spaces ('2023 SEYMOUR AVE'); no situs city field (mailcity is owner mailing city).
How to use it
- QGIS: Layer > Data Source Manager > ArcGIS REST Server, add a connection with the service URL (the endpoint above without the
final
/0), then add the layer. Filter to your area before exporting. - ArcGIS Pro: Add Data > Data From Path, paste the endpoint.
- Direct query: append
/query?geometry=LON,LAT&geometryType=esriGeometryPoint&inSR=4326&spatialRel=esriSpatialRelIntersects&outFields=*&f=geojsonto get the parcel at a point. - CAD: see getting a parcel into AutoCAD or Civil 3D.
Assessor parcel lines are for taxation and are often 5 to 50 ft off the legal boundary. Why.
Basesheet uses this to draw the parcel line on a base plan for any Wyoming address, with LiDAR contours, soils, flood zones and wetlands.
