Orientation Data Overview

The Orientation Data dialog is the primary data input for Dips.

Multiple datasets can be defined. Each dataset typically represents either:

• A grouped collection of discontinuity data (i.e., Spot Mapping)
• A collection of discontinuity data collected on a particular linear or planar feature (i.e., scanline, trace map, borehole) of known orientation, a.k.a., traverse.

For each dataset, the following information is defined:

• Traverse
• Survey Data (if applicable)
• Discontinuities

Traverses are used for the following purposes in Dips:

• To group datasets according to the traverse on which the data was collected using the Traverse Name.
• To weight the data to correct for measurement bias. Weighting is used when the Terzaghi Weighting option is applied and affects:
• Pole vector counts
• Pole intersection vector counts
• Traverses can be used to combine data with different orientation formats (e.g. Dip/Dip Direction and Strike/Dip data) within the same Dips project using the Data Orientation Convention option.
• Traverses can be used to combine data with different unit formats (e.g. Metric and Imperial data) within the same Dips project using the Define Units option.
• Traverses are essential for defining and processing oriented core data using either Linear Borehole Oriented Core or Curved Borehole Oriented Core traverse types.

To enter traverse information:

1. Select Analysis > Orientation Data in the Home ribbon.
2. The Orientation Data dialog appears with a default data set named "Data set 1".
1. Enter a Name for the data set.
2. Select the Type from the drop down.
3. Various options are available in the Traverse, Survey Data and Discontinuities tabs depending on the Type selected.

See the Traverse Types topic for more information.
