How to show strike and dip angle of geologic structures
There is a way of showing the symbols of geological structures (fracture) in his direction of
azimuth using the right hand rule.
Mapping Center Answer:
We do handle symbolizing the strike and dip. In your case, you would:
1. Assign the appropriate marker symbol based on the type of structure.
2. Then set that layer to use rotated point symbols based on your Strike_Azi field. (Advanced button on the layer properties symbology tab). We also have a help topic called: Rotating point feature symbols that discusses how to to this in detail.
3. Then you would set the labeling properties to use the DIP field as the label field. At version 9.3 we’ve also added the ability to set the angle of the DIP label.
There is also an ArcUser article on this subject by Mike Price, who taught me the little bit I know about geologic mapping. You can see that article at:
Mike explains about midway down how to handle the azimuths for the right-hand rule case.
