A Web Map displaying the property ownership boundaries within Natrona County, as well as the municipal boundaries, addresses, Improvement Service District boundaries, streets, roads, Township, Range, and Section Boundaries and zoning boundaries.

The parcel layer is continuously updated & added to over time. In 2003 Premier Data Services, scanned Natrona County Assessors Tax maps to initiate the parcel layer, maps were scanned & digitized. Cleanup was done by Natrona County GIS dept & City of Casper GIS dept. Parcel Data is updated by either importing digital as-built drawings (.dwg CAD format) into the parcel layer or by using the Traverse tool (COGO) to digitally draw in the polygon from a legal description or hard copy of a plat. Digital as-built data is provided by developing companies as a requirement of their contract with the Natrona County Planning department. The digital data is imported into the parcel layer (feature class) first as a polyline data, then polygons are created from the line information using a process within ArcMAP. Accuracy varies based on origin of the source data. The more recent process of using digital as-built CAD data, allows for adjusting older parcel data to the newer data which provides a continuous improvement of the parcel polygon feature class across the coverage area of Natrona County, City of Casper, Bar Nunn, Evansville, Mills, Midwest & Edgerton.
