1. A method for determining a borehole azimuth in a borehole, the method comprising: (a) providing a downhole tool in the borehole, the tool including at least one standoff sensor and an azimuth sensor deployed thereon; (b) causing the at least one standoff sensor and the azimuth sensor to acquire at least one standoff measurement and a tool azimuth measurement at substantially the same time; and (c) processing the standoff measurement, the tool azimuth measurement, and a lateral displacement vector between borehole and tool coordinates systems to determine the borehole azimuth.
