Point along the sensor boresight
direction with the lowest detic altitude. The point is computed in
the sensor's central body fixed coordinate system. The point is
undefined when the boresight direction intersects the ground.

Time. |
| Latitude |
LatitudeUnit |
Real Number |
The detic latitude (i.e., angle between the detic
subpoint's surface normal vector and the XY plane.) |
| Longitude |
LongitudeUnit |
Real Number |
The detic longitude (i.e., angle from the X-axis
locating the projection of the detic subpoint's surface normal
vector onto the XY plane.) Longitude increases in the direction
found using the right-hand rule about the Z-axis. |
| Altitude |
DistanceUnit |
Real Number |
The altitude value (i.e., magnitude of the relative
position vector between the object and its detic subpoint). |
| 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. |
