Townships are normally a square approximately six miles (9.7 km) on a side with cardinal boundaries conforming to meridians and parallels, containing 36 sections of one square mile (2.6 km 2) each. Townships were originally surveyed and platted by the United States General Land Office, using contracted private survey crews, and are marked on the United States Geological Survey maps of the United States. A reference to the township will look something like "Township 2 North Range 3 East", or "T2N,R3E" and such a notation is used in property descriptions based on the PLSS. Survey townships are generally referred to by a number based on the Public Land Survey System (PLSS). ![]() Main article: Survey township Diagram of survey township Hierarchy of systemic numbering in the PLSS Provided certain conditions are met, a charter township is mostly exempt from annexation to contiguous cities or villages, and carries additional rights and responsibilities of home rule. A charter township, found only in the state of Michigan, is similar to a civil township.Civil townships are generally given a name, sometimes written with the included abbreviation "Twp". Counties are the primary divisional entities in many states, thus the powers and organization of townships varies from state to state. A civil township is a unit of local government, generally a civil division of a county.A survey township is nominally six by six miles square, or 23,040 acres. A survey township is simply a geographic reference used to define property location for deeds and grants as surveyed and platted by the General Land Office (GLO).Learn more about how to use custom grids.Term for several types of geographic areasĪ township in some states of the United States is a small geographic area. One example of a custom grid is a township and range grid, shown below. The polygon or line feature acts as the grid lines, and the custom grid allows you to label those lines outside the map frame. Custom gridĪ custom grid is based on a polygon or line feature in a map. Learn more about how to use reference grids. They are used to visually divide the map, independent of the coordinate system, to allow simple location referencing. Reference gridĪ reference grid is a network of columns and rows used to divide a map into equal-area rectangles. It is used to show locations in a UTM coordinate system and display MGRS-specific information, such as 100,000-meter grid designators. Military Grid Reference System (MGRS) grid is a special type of measured grid. Learn more about how to use measured grids. They are used to show location using projected coordinates. Measured gridĪ measured grid is a network of evenly spaced horizontal and vertical lines used to identify locations on a map. They are used to show location in geographic coordinates (degrees of latitude and longitude). Graticules are lines showing parallels of latitude and meridians of longitude for the earth. Grids are used to show coordinates or divide the map frame. ![]() There are five types of grids that can be added to a map frame: graticules, measured grids, MGRS grids, reference grids, and custom grids.
