  2. State Plane Coordinate System - Wikipedia

    en.wikipedia.org/wiki/State_Plane_Coordinate_System

    The State Plane Coordinate System ( SPCS) is a set of 125 geographic zones or coordinate systems designed for specific regions of the United States. Each U.S. state contains one or more state plane zones, the boundaries of which usually follow county lines. There are 108 zones in the contiguous United States, with 10 more in Alaska, five in ...

  3. Lambert conformal conic projection - Wikipedia

    en.wikipedia.org/wiki/Lambert_conformal_conic...

    A Lambert conformal conic projection ( LCC) is a conic map projection used for aeronautical charts, portions of the State Plane Coordinate System, and many national and regional mapping systems. It is one of seven projections introduced by Johann Heinrich Lambert in his 1772 publication Anmerkungen und Zusätze zur Entwerfung der Land- und ...

    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.

  5. United States National Grid - Wikipedia

    en.wikipedia.org/wiki/United_States_National_Grid

    The United States National Grid (USNG) is a multi-purpose location system of grid references used in the United States. It provides a nationally consistent "language of location", optimized for local applications, in a compact, user friendly format. It is similar in design to the national grid reference systems used in other countries.

  7. Spatial reference system - Wikipedia

    en.wikipedia.org/wiki/Spatial_reference_system

    Geodesy. A spatial reference system ( SRS) or coordinate reference system ( CRS) is a framework used to precisely measure locations on the surface of Earth as coordinates. It is thus the application of the abstract mathematics of coordinate systems and analytic geometry to geographic space. A particular SRS specification (for example ...

    SGL 31 was entered into the Geographic Names Information System on 2 August 1979 as identification number 1188510. Elevations range from 1,340 feet (410 m) to 2,046 feet (624 m), located on a single parcel at 41°2′17″N 79°1′5″W  /  41.03806°N 79.01806°W  / 41.03806; -79.

  9. Projected coordinate system - Wikipedia

    en.wikipedia.org/wiki/Projected_coordinate_system

    Geodesy. A projected coordinate system – also called a projected coordinate reference system, planar coordinate system, or grid reference system – is a type of spatial reference system that represents locations on Earth using Cartesian coordinates ( x, y) on a planar surface created by a particular map projection.
