- Precision scope
- Centroid of the Loudoun County LOLA application polygon for Project Celtics Phase 2 (EPLAN-2023-0063), a two-part property of 145.02 geodesic acres, about 0.8 by 1.7 km. The same polygon is used for the Phase 1 plans. It locates the campus, not Building 5: the Building 5 address point is about 140 m south-south-east. It is not a footprint or works extent.
- Horizontal uncertainty
Not reported
The county publishes no positional accuracy for application polygons; the centroid represents a 145-acre, two-part campus.

A locator places the site on the map. It is not a building footprint, a construction extent or a surveyed boundary unless the use scope is an official boundary, and even then it is a parcel or permit boundary.
