Map sources and method

The state outline is adapted from the U.S. Census Bureau 2025 cartographic boundary file. Facility coordinates are adapted from Compute Atlas by Edward Kubiak, edition 1.34.1, under CC BY 4.0. Outline and markers use one geographic projection before any explicitly disclosed readability offset. Exact singleton source anchors are never moved. A one-kilometre boundary tolerance prevents the simplified 1:20,000,000 outline from hiding legitimate border-area source points; farther conflicts are disclosed, not clamped. DataCenterData groups source-reported city coordinates only within a bounded map radius; the outline does not validate a facility record. Some locations in this layer are reported by the provider as derived from OpenStreetMap (© OpenStreetMap contributors, ODbL, https://www.openstreetmap.org/copyright) and Epoch AI (CC BY 4.0).

Two layers, two jobs. These licensed rows have not been independently verified by DataCenterData and are not a census. Reviewed evidence remains separate.
