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.
