Topological rules were validated in ArcGIS Pro. Polygons evaluated for gaps, overlaps, and correct spatial relationships.
Features were extracted and verified against real-world conditions observed in 2024 imagery.
All vector-based planimetric data adheres to the ASPRS Positional Accuracy Standards for Digital Geospatial Data, Edition 2, Version 2.0 (2024). The target threshold and overall goal for variation between the planimetric data and the provided 3-inch resolution, leaf-off orthophotography captured in Spring 2024 is 4.75 feet (144.78 cm) or less per vertex and edge.
Data assessment and update. A hybrid workflow of automated processes and manual (four-eyes) heads-up digitization was used to conform geometry to the 2024 3-inch orthophotography. Features identified as pre-existing were populated with a created_date of 01/01/2020.
