Traverses Overview

Traverses are lines or surfaces of known orientation on which joint/discontinuity data has been collected. Traverses are defined in the Orientation Data dialog.

Name

The Name of the Orientation Data data set is used as a unique identifier for the Traverse and also appears in the Pole Data Grid under the "Traverse" column to identify processed poles measured on each Traverse.

Type

Several Traverse Types can be defined:

• Spot Mapping
• Linear Scanline
• Planar
• Linear Borehole Oriented Core
• Linear Borehole Televiewer
• Curved Borehole Oriented Core
• Curved Borehole Televiewer
• Clinorule

Traverse Format

The Traverse Format in the Traverse tab of the Orientation Data dialog refers to the format used to define the orientation of the Traverse (if applicable). Depending on the Traverse Type selected, various Traverse Formats are available. See the Traverse Format topic for more information.

Declination can be optionally specified to account for the Declination correction of the Traverse Format and Discontinuities measured on this Traverse. See the Declination topic for more information.

Geographic Coordinate System

The Geographic Coordinate System is defined by:

• Longitude
• Latitude
• Elevation

Local Coordinates

The Local Coordinates is defined by:

• X (Easting)
• Y (Northing)
• Z (Elevation)

This coordinate system is used to represent location in model space, but can also represent the Universal Transverse Mercator (UTM) coordinate system for your UTM zone designation. For a borehole, this should represent the collar location.

Comments

Optionally enter Comments for record keeping.

Units

Units can be defined for unit-sensitive inputs such as the Elevation, Local Coordinates (X, Y, Z), and Depth by selecting the Define Units button.

In the Define Unit dialog:

• Elevation Units are restricted to Data Type = Length
• XYZ Units are restricted to Data Type = Length
• Depth Units are restricted to Data Type = Length
