Points of the pattern that represent
intersection of boundary of the sensor field-of-view with the
ground surface. Points are computed in the sensor's central body
fixed coordinate system. Additionally, on a Sensor's 2D Graphics
Projection properties page, if "Use" is enabled under Extension
Distances, points on set altitude projection levels are reported;
if Show Intersections is set to Terrain, non-zero altitude values
are reported for the pattern intersection and if set to Central
Body, the altitude is always 0.

Description |
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). |
CBF X |
DistanceUnit |
Real Number |
The X component of the position vector of the
intersection point, expressed in the sensor's central body fixed
system. |
CBF Y |
DistanceUnit |
Real Number |
The Y component of the position vector of the
intersection point, expressed in the sensor's central body fixed
system. |
CBF Z |
DistanceUnit |
Real Number |
The Z component of the position vector of the
intersection point, expressed in the sensor's central body fixed
system. |
Range |
DistanceUnit |
Real Number |
The range (i.e., distance between the primary and
secondary object) at the given time. |
Distance AlongGroundTrack |
DistanceUnit |
Real Number |
A measure of distance to the intersection point
along the ground track direction. Points forward of the sensor's
detic subpoint are considered to have positive distances while
points behind the detic subpoint will have negative distances. The
distance is computed from the detic subpoint to the projection of
the intersection point to a plane through the detic subpoint
aligned with the ground track at that point. |
Distance PerpToGroundTrack |
DistanceUnit |
Real Number |
A measure of distance to the intersection point
perpendicular to the ground track direction. Points left of the
sensor's detic subpoint are considered to have positive distances
while points right of the detic subpoint will have negative
distances. The distance is computed from the detic subpoint to the
projection of the intersection point to a plane through the detic
subpoint perpendicular to the ground track at that point. |
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. |
