OpenHistoricalMap: Doing History
summary
Overlaying 17th–19th century maps on OpenStreetMap with MapWarper exposes concrete problems and solutions: a phantom “Sea of the West” persists for 200 years, the 1695 Miller map is drawn from memory after notes were lost and misplaces streets, colonial building facades — not modern curbs — provide true anchors, Fort Orange is located beneath I‑787, precise 1900 Cope surveys geo‑reference cleanly, while Elliott’s burial map is stretched so projects must align piecewise.
