Stereonet View
The Stereonet View option displays a stereographic projection of your wedge orientation data. Plane orientations can be displayed as great circles and/or poles, joint intersections can be displayed and data corresponding to failed wedges can be highlighted.
You can access the Stereonet View at any time by selecting:
- the Stereonet toolbar button
- Stereonet from the Analysis menu
The following Stereonet viewing options are available in the right-click menu, the Stereonet sub-menu of the View menu or the Display Options dialog.
Show Planes
The Show Planes option will display the planes (great circles) corresponding to the current orientations of Joint1, Joint2, slope, upper face, tension crack and basal joint.
Show All Poles
The Show All Poles option will display the poles corresponding to the current orientations of Joint1, Joint2, slope, upper face, tension crack and basal joint. For a Probabilistic analysis, this option will display all statistically generated pole orientations. For a Combination analysis, this option will display all joint poles used in the analysis.
Show Intersections
The Show Intersections option toggles the display of joint intersections on the stereonet. A joint intersection represents the orientation of the line of intersection of two joint planes forming a wedge. This is applicable for Probabilistic or Combination analysis.
Show Failed
The Show Failed option highlights all intersections and corresponding joint poles, which represent a wedge with a safety factor < 1. This is applicable for Probabilistic or Combinations analysis. The Show All Poles or Show Intersections options must also be selected in order for this option to apply. Failed orientations are highlighted in red.
Equal Angle / Equal Area Projection
You may choose either Equal Angle or Equal Area stereographic projection methods. By default, the Equal Angle method is in effect. For more information on stereographic projection methods, see the Dips help system.
Lower/Upper Hemisphere Projection
You may choose either Lower Hemisphere or Upper Hemisphere projection. By default, the Lower Hemisphere option is in effect. An upper hemisphere projection is equivalent to a lower hemisphere projection rotated by 180 degrees and represents the traces of planes and poles projected onto the upper hemisphere when viewed from above.
