  2. State Plane Coordinate System - Wikipedia

    en.wikipedia.org/wiki/State_Plane_Coordinate_System

    Thus the state plane coordinate system is still useful. Originally, the state plane coordinate systems were based on the North American Datum of 1927 (NAD27). Later, the more accurate North American Datum of 1983 (NAD83) became the standard (a geodetic datum is the way a coordinate system is linked to the physical Earth). More recently there ...

    Primarily from the United States Government Printing Office Style Manual. [1] State names usually signify only parts of each listed state, unless otherwise indicated. Based on the BLM manual's 1973 publication date, and the reference to Clarke's Spheroid of 1866 in section 2-82, coordinates appear to be in the NAD27 datum.

    Each state has its own set of reference parameters given in the standard. [8] The U.S. National Geodetic Survey's "State Plane Coordinate System of 1983" uses the Lambert conformal conic projection to define the grid-coordinate systems used in several states, primarily those that are elongated west to east such as Tennessee.

    In the first half of the 20th century, State Plane Coordinate Systems (SPCS) brought the simplicity and convenience of Cartesian coordinates to state-level areas, providing high accuracy (low distortion) survey-grade coordinates for use primarily by state and local governments. (Both of these planar systems remain in use today for specialized ...

  6. Universal Transverse Mercator coordinate system - Wikipedia

    en.wikipedia.org/wiki/Universal_Transverse...

    Specifying a location means specifying the zone and the x, y coordinate in that plane. The projection from spheroid to a UTM zone is some parameterization of the transverse Mercator projection. The parameters vary by nation or region or mapping system. Most zones in UTM span 6 degrees of longitude, and each has a designated central meridian ...

    The Western Ohio Seismic Zone and a portion of the Southern Great Lakes Seismic Zone are located in the state, and numerous faults lie under the surface. [ 114 ] [ 115 ] The most substantial known earthquake in Ohio history was the Anna (Shelby County) earthquake, [ 116 ] which occurred on March 9, 1937.
