Stereonet Charts

To access this screen:

  • Display the Stereonet screen and select the Charts tab.

The Charts tab of the Stereonet screen is used to show or hide poles, planes, contours, and a colour map.

You can also define projection, net type, hemisphere, grid, and colour settings for the stereonet plot.

Activity Steps:

  1. Display the Stereonet screen and load data.

  2. Use the chart arrow buttons to manage the listed stereonet charts if any are already displayed, otherwise, skip this step.

    • Click Move Record Up or Move Record Down to change the order of the listed charts.

    • Click Select Previous or Select Next to select another chart in the list.

    • Click Delete Selected Chart to delete the selected chart.

  3. In the Stereonet pane, select the stereonet chart to configure.

    The Stereonet pane displays the stereonet charts generated on the previous tab.

  4. Review the Display controls.

    The Display controls apply only to the chart selected in the Stereonet pane.

  5. In Show/Hide, select whether to display stereonet elements:

    • Select Poles to display structure points as poles on the stereonet. Default: selected.

    • Select Contours to display stereonet contours. Contours are typically used with an equal-area projection.

    • Select Planes to display structure points as planes, or great circles, on the stereonet.

    • Select Title to display the stereonet title.

    • Select Color Map to display a colour map of pole density.

  6. Select the required colour map type from the Color Map Type list.

  7. In Projection, select the projection type:

    • Select Equal Area to display an equal-area, or Schmidt, projection of the data. Use this projection when solving angular relationships and statistically evaluating orientation data using contours. Default: selected. See Schmidt Projection.

    • Select Equal Angle to display an equal-angle, or Wulff, projection of the data. Use this projection when solving angular relationships. See Wulff Projection.

    Equal-area and equal-angle projections:

  8. In Net, select the stereonet type:

    • Select Polar to display a polar projection. Default: selected.

    • Select Equatorial to display an equatorial projection.

    Equal-area polar and equatorial projections:

  9. In Hemisphere, select the hemisphere type:

    • Select Lower to display a lower hemisphere projection. This is the most commonly used projection for structural data. Default: selected.

    • Select Upper to display an upper hemisphere projection.

    Equal-area, polar, lower and upper hemisphere projections:

  10. In Grid, select whether to display grid labels and guides:

    • Select NSEW to label the stereonet with the four cardinal directions. Default: selected.

    • Select Center Cross to display a blue centre cross. Default: selected.

    • Select Outer Circle to display the blue outer circle. Default: selected.

    • Select Cross Hairs to display blue north-south and east-west lines.

  11. In Colors, select stereonet colours:

    • Select Background to set the stereonet plot background colour.

    • Select Net to set the stereonet grid line colour. Default: grey.

    • Select Grid to set the colour for NSEW, Center Cross, Outer Circle, and Cross Hairs. Default: blue.

Note: The Stereonet screen is modeless. You can leave it open while you run commands in 3D and other windows.
