Name Dimension Type Description
Cartesian-x DistanceUnit Real Number The X component of the center of the ground ellipse with respect to object's central body fixed coordinate system.
Cartesian-y DistanceUnit Real Number The Y component of the center of the ground ellipse with respect to object's central body fixed coordinate system.
Cartesian-z DistanceUnit Real Number The Z component of the center of the ground ellipse with respect to object's central body fixed coordinate system.
Geodetic-Lat LatitudeUnit Real Number The detic latitude of the center of the ground ellipse.
Geodetic-Lon LongitudeUnit Real Number The detic longitude of the center of the ground ellipse.
Geodetic-Alt DistanceUnit Real Number The detic altitude of the object relative to the center of the ground ellipse.
Geocentric-Lat LatitudeUnit Real Number The centric latitude of the detic subpoint (i.e. angle between the subpoint position vector and the XY plane of the object's central body fixed axes.)
Geocentric-Lon LongitudeUnit Real Number The centric longitude of the detic subpoint (i.e. angle from the X-axis locating the projection of the subpoint position vector onto the XY plane of the object's central body fixed axes.) Longitude increases in the direction found using the right-hand rule about the Z-axis.
Geocentric-Alt DistanceUnit Real Number The altitude value (i.e., magnitude of the relative position vector between the object and its detic subpoint). Its value is the sum of the ground altitude and the height above ground.
Spherical-Lat LatitudeUnit Real Number The signed angle measured from the XY plane to the position vector, where positive angles are used for locations above the XY plane, and negative for those below.
Spherical-Lon LongitudeUnit Real Number The signed angle measured from the X axis to the projection of the position vector into the XY plane. The angle increases in the direction found by the right hand rule about the Z axis.
Spherical-Rad DistanceUnit Real Number The magnitude of the position vector (i.e. the radius vector).
Cylindrical-R DistanceUnit Real Number The radius value of the cylindrical coordinate representation of the position vector, where the cylinder's symmetry axis is the Z axis. Its value is the magnitude of the projection of the position vector into the XY plane of the object's central body fixed axes.
Cylindrical-Lon LongitudeUnit Real Number The signed angle measured from the X axis to the projection of the position vector into the XY plane. The angle increases in the direction found by the right hand rule about the Z axis.
Cylindrical-Z DistanceUnit Real Number The Z component of the position vector.
Alt AGL DistanceUnit Real Number The altitude above ground level. The difference between the altitude and the terrain altitude. If no terrain is found at the detic subpoint, then the string "No Terrain" is returned.
Ground Alt DistanceUnit Real Number The altitude of the ground.
Terrain Alt DistanceUnit Real Number or Text The terrain altitude. The altitude of the terrain located at the detic subpoint's latitude and longitude, measured from the object's central body surface along the surface normal through the detic subpoint. If no terrain is found at the detic subpoint, then the string "No Terrain" is returned.
Alt MSL DistanceUnit Real Number The altitude above mean sea level. The difference between the altitude and the height of mean sea level, measured from the object's central body surface along the surface normal through the detic subpoint.
Ground Alt MSL DistanceUnit Real Number The altitude of the ground, expressed with respect to mean sea level.
UTM Zone Unitless Text The UTM Zone character indicator for the detic subpoint. Available only when the central body is Earth.
UTM Easting DistanceUnit Real Number The easting value within the UTM zone for the detic subpoint. Available only when the central body is Earth.
UTM Northing DistanceUnit Real Number The northing value within the UTM zone for the detic subpoint. Available only when the central body is Earth.
MGRS Cell Unitless Text The MGRS (Military Grid Reference System) code for the cell area containing the detic subpoint. Available only when the central body is Earth.
