Michigan PLSS Converter — Section Township Range to GPS

Michigan's Public Land Survey System is governed by the Michigan Meridian, established in 1815 with its initial point near the mouth of the Miami River in present-day Ohio. The Michigan Meridian covers all of Michigan's two peninsulas — the Lower Peninsula and the Upper Peninsula — as well as parts of Indiana and Ohio. Its use across a state divided by water into two distinct land masses makes Michigan's PLSS geography particularly interesting: the same meridian and baseline govern both the agricultural Lower Peninsula and the heavily forested, mining-rich Upper Peninsula.

The Lower Peninsula was surveyed rapidly in the 1820s through 1840s as federal land sales fueled settlement along the Great Lakes corridor. The flat to rolling terrain of the Lower Peninsula's interior — underlain by glacial till and outwash — allowed accurate rectangular surveys, and the Lower Peninsula's 68 counties show the regular grid structure that characterizes well-surveyed agricultural states. The Detroit metropolitan area, now one of the largest urban complexes in the Midwest, was originally surveyed as farmland, and many of its suburban parcel descriptions trace back to original Michigan Meridian quarter sections that were subdivided through platting over the last 150 years.

The Upper Peninsula presents a very different PLSS environment. The rugged terrain of the Huron Mountains, the copper and iron ore districts of Keweenaw, Houghton, Baraga, and Marquette counties, and the dense conifer and hardwood forests of Luce, Chippewa, and Schoolcraft counties all complicated original surveys. The UP's shorelines along Lakes Superior, Michigan, and Huron generated extensive government lot descriptions that appear throughout northern Michigan real estate titles. Mining company land grants in the UP were some of the largest private land transactions in American history, and the PLSS descriptions from those grants still anchor many UP land titles today.
