Whisker lines are lines going some distance from a selected point in a given bearing and opposite bearing. These are used in seismic surveys to determine the coverage of seismic survey points.
The Create Whisker Lines from Points tool is found under the Advanced Feature Creation Options sub-menu of the Digitizer menu or context menu. To activate this option in the Advanced Feature Creation Options menu, first select a point feature or features with the Digitizer Tool.
Once activated, the Specify Length and Direction of Whisker Line dialog will appear.
Choose to specify the lines either by a fixed X and Y offset, or with a distance and bearing.
The opposite direction will be added to the whisker line as well.
See also the radial lines option in Create Range Rings / Ellipses and Create New Point/ Text Feature At Specified Bearing/ Distance for similar tools.
