The measurement of discontinuity (joint) orientations is critical in assessing the stability of discontinuous rock slopes. The discontinuity orientations are used as input to all discontinuous modeling programs and methods, including kinematic screening methods and limited equilibrium sliding methods.

Traditionally, discontinuity orientations are measured manually using a compass (Figure 1). The drawbacks of this method include the fact that these measurements are slow, are tedious, often subject the user to physical danger (from rock falls and/or the need to scale slopes for measurements at heights), and may be inaccurate due to sampling biases when measurements are restricted to...
