An improved edition of a map of the surveyed parts of the Territory of Michigan (Farmer, 1836)
John Farmer’s map of the surveyed part of Michigan Territory, engraved and published by J. H. Colton in New York in 1836: the lower peninsula from Lake Michigan to the Detroit and St. Clair rivers and north to Saginaw, laid out in its counties, townships and sections, with the strip of northern Ohio and Indiana below the disputed state lines (Harris’s line of 1817 and the line of 1818 both drawn). It shows the towns, mills and post offices of the land rush and its roads — the Chicago Road, the Territorial and Saginaw roads, the U.S. Turnpike to the Maumee and the Erie and Kalamazoo Rail Road — and the Anishinaabe (Ojibwe, Odawa, Potawatomi) and Wyandot country they crossed: Indian villages on the St. Joseph, the Coldwater, the Thornapple, the Flint and the Grand, the reserves kept in the treaties of 1807–1821 (the Wyandot reserve at Brownstown, the reserves on the Cass and Flint above Saginaw, the Indian reserve on the Coldwater, the Ottawa reserve on the Maumee), the “Indian Boundary Line” and the “Indian Country” north of the Grand River, and, in fine dots, the trails — the “Chicago Trail” beside the Chicago Road, “St. Joseph’s Trail” across Jackson and Washtenaw, the “Washtenaw Trail”, the “Hog R. Trail” and an “Indn Trail” among others. The unsurveyed country north of the Grand River, sketched too freely to place, is not shown; nor are the title and the insets of Mackinac, Green Bay and the lead mine district.

| Accuracy | About 4 km (RMS 1.4 km at 60 control points). Placed by hand in a map-queue session and approved by a person. If something sits in the wrong place, members can fix it with Fix placement on the map. |
| Method | Placed by hand: a second-degree polynomial through 60 places read from the scan — 50 towns (from Detroit, Monroe, Toledo and Sandusky to St. Joseph, Michigan City, Grand Haven and Saginaw), the Lake Erie islands and Point Pelee, the mouth of the Saginaw River and the initial point of the Michigan survey — and matched to their positions today. The surveyed townships are drawn closely: left out of the fit in turn, half the places fall within 1.1 km of where it puts them (RMS 1.5 km; Grand Haven, Ionia and the islands furthest, about 3 km). The unsurveyed country north of the Grand River is masked: the map draws the Lake Michigan shore there freely, putting the mouths of the Muskegon and the White River some 9 and 15 km from where they are.
