This frame has the Z axis aligned with the outward surface normal direction and the X axis constrained toward the local north direction.

Name	Dimension	Type	Description
Normal x	Unitless	Real Number	First component of the unit vector along the normal to the selected plane in the reference coordinate system. Defines projection of the unit vector onto the x-axis of the reference coordinate system.
Normal y	Unitless	Real Number	Second component of the unit vector along the normal to the selected plane in the reference coordinate system. Defines projection of the unit vector onto the y-axis of the reference coordinate system.
Normal z	Unitless	Real Number	Third component of the unit vector along the normal to the selected plane in the reference coordinate system. Defines projection of the unit vector onto the z-axis of the reference coordinate system.
Slope	AngleUnit	Real Number	The slope of the ground relative to the local horizontal plane. Zero indicates level ground. Value is independent of selected coordinate system.
Azimuth	LongitudeUnit	Real Number	Dihedral angle between north vector and velocity vector about the detic nadir vector. The velocity vector is the velocity of the object, as observed in the object's central body fixed coordinate system.
