How To Draw Stereonet: Great Circles, Dip and Dip Direction | Step by Step Procedure

Discontinuities (joints) in rock mass can be characterised by their direction, which included dip and dip direction. See this video How to Measure Dip and Dip Direction ... to learn how to measure dip and dip direction. It is important to know how to interpret this type of data; and the first thing that a practitioner must know is how to draw great circles of discontinuities using a stereonet. Then, you can analyse the plot and, for example, use it to estimate the stability of rock slopes.
This video will explain how to draw two different sets of data on a stereonet.
