The township and range system is a rectangular land survey method created by the Land Ordinance of 1785 that divides US land into 6-mile-square townships and 1-square-mile sections, producing the geometric fields, right-angle roads, and dispersed farmsteads visible across the American Midwest and West.
The township and range system (also called the Public Land Survey System) is how the United States carved up land west of the Appalachians after the Land Ordinance of 1785. Surveyors started from principal meridians and baselines, then drew a giant grid. Each township is six miles by six miles, and each township splits into 36 sections of one square mile (640 acres) each. Sections could be subdivided further and sold off in neat rectangular chunks.
For AP Human Geography, this isn't a history fact. It's a cultural landscape. Fly over Iowa or Kansas and you see the system written on the ground in square fields, roads that meet at perfect right angles, and farmhouses spaced evenly apart instead of clustered in villages. That checkerboard is exactly what the CED means by land-use patterns as expressions of culture (3.2.A). The grid reflects American values at the time, like efficient land sales, individual ownership, and rational planning, which connects it to 3.2.B's idea that landscapes reflect cultural beliefs.
This term lives in Topic 3.2: Cultural Landscapes in Unit 3 and supports learning objectives AP Human Geography 3.2.A (describe the characteristics of cultural landscapes) and AP Human Geography 3.2.B (explain how land and resource use reflect cultural beliefs and identities). Survey systems are one of the cleanest examples of culture stamped onto land. The exam loves them because they're visual. You can identify township and range from a satellite image alone, which makes it perfect material for stimulus-based multiple choice. It also creates a settlement-pattern story (dispersed farmsteads rather than clustered villages) that carries forward into rural land use in Unit 5.

Section (Unit 3)
A section is the basic building block of township and range. Each 6x6 mile township contains 36 numbered sections of one square mile each, and those sections became farms, school lands, and homestead claims.
Meridian (Unit 3)
The whole grid hangs off principal meridians and baselines. Surveyors measured townships north-south from a baseline and east-west from a meridian, which is literally where the words 'township' and 'range' come from.
Plat Map (Unit 3)
Plat maps are the paper version of the grid. They record how townships and sections were subdivided into individual parcels, so a plat map is the legal document that turns the survey system into property lines you can buy and sell.
Built Environment (Unit 3)
Township and range is a textbook case of the built environment. Humans imposed an abstract grid onto physical terrain, and that decision still controls where roads, fields, and even county lines sit more than 200 years later.
This term shows up most often in image-based multiple choice. A typical stem describes or shows a satellite view with geometric field patterns, straight roads meeting at right angles, and evenly spaced farmsteads, then asks which survey system produced it. That description is township and range, full stop. The trap answers are usually long-lot (narrow strips perpendicular to a river, common in Quebec and Louisiana) and metes and bounds (irregular parcels based on natural features, common in the eastern US). No released FRQ has used the term verbatim, but survey systems make strong evidence in any FRQ about cultural landscapes, sequent occupancy, or rural settlement patterns. Your job is to match the visual pattern to the system, name the culture behind it, and explain the settlement pattern it created (dispersed, not clustered).
Both are survey systems, but they look completely different from above and come from different cultures. Township and range is a rigid grid of squares imposed by the US government, ignoring rivers and terrain, and it produced dispersed farmsteads. Long-lot, used by French settlers in Quebec and Louisiana, creates narrow strips of land running perpendicular to a river so every farm gets water access, producing a linear settlement pattern with houses lined up along the waterway. If the image shows squares and right angles, it's township and range. If it shows skinny ribbons off a river, it's long-lot.
The township and range system came from the Land Ordinance of 1785 and divides US land into 6-mile-square townships, each containing 36 one-square-mile sections.
On satellite images, township and range looks like a checkerboard of square fields, roads at right angles, and evenly spaced farmsteads, which is the giveaway on stimulus questions.
It produced a dispersed rural settlement pattern, with individual farmhouses scattered across the grid instead of clustered in villages.
It's a cultural landscape under Topic 3.2 because the grid reflects American cultural values like efficient land sales, individual property ownership, and rational planning.
Don't confuse it with long-lot (narrow river strips, French influence) or metes and bounds (irregular parcels following natural features, eastern US).
It's the rectangular land survey system created by the Land Ordinance of 1785 that divides US land into 6x6 mile townships and 36 one-square-mile sections each. On the AP exam it's a key example of a cultural landscape in Topic 3.2.
Township and range is a uniform government-imposed grid of squares, mostly west of the Appalachians. Metes and bounds uses natural features like rivers, trees, and rocks to define irregular parcel boundaries, and it dominates the eastern US, which is why eastern property lines look so messy by comparison.
No. Township and range creates square parcels in a grid that ignores rivers, while long-lot creates narrow strips perpendicular to a river so every parcel touches the water. Long-lot reflects French settlement in Quebec and Louisiana; township and range reflects post-1785 American planning.
Look for geometric square fields, roads intersecting at right angles, and farmsteads spaced evenly across the landscape. If parcels are narrow ribbons running off a river instead, the answer is long-lot, not township and range.
Because it's a human idea physically imprinted on land. The 1785 grid reflects American beliefs about efficient land distribution and private ownership, and the resulting field patterns, road networks, and dispersed farmsteads are still visible today, which is exactly what learning objectives 3.2.A and 3.2.B describe.
