| Description: The grid_coordinate_system_name attribute provides the name of the grid coordinate system. These are currently defining Earth-centric gridded systems and remain incase they are used for PDS archives or grid systems are implemented for non-Earth bodies. |

| | ARC Coordinate System | The Equal Arc-second Coordinate System is a plane-rectangular coordinate system established by the Department of Defense in 1990. |
| | Other Grid System | Allows for a grid system not defined elsewhere. The information provided should include the name of the grid system, the names of the parameters and values used for the data set, and the citation of the specification for the algorithms that describe the mathematical relationship between the body and the coordinates of the grid system. |
| | State Plane Coordinate System 1927 | In the United States, it is the projection used in the State Plane Coordinate System (SPCS) for States with predominant north-south extent. (The Lambert Conformal Conic is used for the others, except for the panhandle of Alaska, which is prepared on the Oblique Mercator. Alaska, Florida, and New York use both the Transverse Mercator and the Lambert Conformal Conic for different zones). Except for narrow States, such as Delaware, New Hampshire, and New Jersey, all States using the Transverse Mercator are divided into two to eight zones, each with its own central meridian, along which the scale is slightly reduced to balance the scale throughout the map. Each zone is designed to maintain scale distortion within 1 part in 10,000. 1927 refers to the use of the 1927 North American Datum (NAD27). |
| | State Plane Coordinate System 1983 | In the United States, it is the projection used in the State Plane Coordinate System (SPCS) for States with predominant north-south extent. The Lambert Conformal Conic is used for the others, except for the panhandle of Alaska, which is prepared on the Oblique Mercator. Alaska, Florida, and New York use both the Transverse Mercator and the Lambert Conformal Conic for different zones. Except for narrow States, such as Delaware, New Hampshire, and New Jersey, all States using the Transverse Mercator are divided into two to eight zones, each with its own central meridian, along which the scale is slightly reduced to balance the scale throughout the map. Each zone is designed to maintain scale distortion within 1 part in 10,000. In the name, 1983 refers to the use of the 1983 North American Datum (NAD83). |
| | Universal Polar Stereographic | Like Universal Transverse Mercator (UTM), UPS is a method used to generally split up the Earth into quads. When the latitude is from 84 degrees North and 80 degrees South to the respective poles, the (UPS) projection is used. |
| | Universal Transverse Mercator | The UTM is the ellipsoidal Transverse Mercator to which specific parameters, such as central meridians, have been applied. This is generally used for Earth. Latitudes between 84 degrees North and 80 degrees South is divided into 60 zones each generally 6 degrees wide in longitude. Bounding meridians are evenly divisible by 6 degrees, and zones are numbered from 1 to 60 proceeding east from the 180th meridian from the Prime Meridian (e.g., Greenwich) with minor exceptions. |
