cbrn:RelativeLocationInclinationValue

A vertical bearing angle with respect to the horizontal plane from a reference point (Origin) to an object (i.e., instrument, detector, or item) or a nuclide.  Its value is the angle subtended by a straight line, running from the center of the reference point to the center of the object or nuclide, and a projection of that line onto the horizontal plane. The angle range is from "-90.0" to "+90.0" degrees. A value of zero implies the center of the object or nuclide is at the same altitude or elevation as the reference point; positive values imply the object or nuclide is higher than the reference point; negative values imply the object or nuclide is lower than the reference point.
