Orientation Data Formats
Dips allows the user to toggle the format of the orientation coordinates with the Convention option under the Setup menu.
If the convention is Pole Vector, the coordinates will be in Trend / Plunge format, and represent the cursor (pole) location directly.
If the convention is Plane Vector, the coordinates will correspond to the Global Orientation Format of the current document (ie. Dip/Dip Direction, Strike/DipRight, Strike/DipLeft), and represent the plane corresponding to the cursor (pole) location.
The convention can also be switched in the Job Control Dialog. It lets the user to specify the Global Orientation Format.
Oriented Core (borehole) Data
Dips enables the user to analyze orientation data measured from the logging of core from a borehole. Borehole data can be added by defining the Traverse Type as Borehole. 3 traverse orientations must be given for borehole traverses.
If the orientation data was measured from the logging of core from a borehole, then the data pair columns must then contain the measurements of the "Alpha" and "Beta" angles.
Dips enables the user to analyze joint orientations of magnetic orebodies measured with a device called clinorule. Clinorule data can be added by defining the Traverse Type as Clinorule.
For Clinorule traverses, the azimuth of the reference line is input in the Traverse Information dialog as the Orientation 1 of the traverse.
Mixed Orientation Data Formats
Dips allows the user to combine mixed orientation formats in the same document by modifying the Traverse Orientation Format. Whenever the Traverse Orientation Format is different from the Global Orientation Format, Dips will interpret the orientation data for the Traverse according to the Traverse Orientation Format.
Traverses / Terzaghi Bias Correction
The Terzaghi Weighting option, available in the View menu and the View toolbar, can be applied to Contour and Rosette plots, to account for the sampling bias introduced by orientation data collection along Traverses.
The Declination in the Job Control dialog can be used for azimuth correction. This is typically used to correct for magnetic declination, but can be used to adjust to grid north.
In Dips, any columns after the two mandatory Orientation Columns, and the optional Quantity and Traverse Columns, are referred to as Extra Columns. Extra Columns can be used to store any other quantitative or qualitative data, such as information about data type, discontinuity spacing, joint roughness, or seismic velocity.
