Such static and dynamic surveying measurements commonly include borehole inclination and borehole azimuth measurements that describe the current direction of drilling. Borehole inclination is an angular measurement that describes the deviation of the borehole from vertical while borehole azimuth is an angular measurement that describes the deviation of the borehole from a reference direction (e.g., magnetic or true north) in the horizontal plane
