Arrows pointing to compass direction in attribute of point feature
I am plotting permanent photo monitoring locations on an interactive map, and would like to symbolize the direction in which the photo was taken (as recorded in degrees in a "compass direction" field in the attribute table of a point feature class. How should I approach this?
Mapping Center Answer:
On the layer properties dialog's symbology tab, use the Advanced button and choose Rotation. This will ask for a rotation field that contains the angle that will be used to orient the marker symbol.
Late last year we wrote a blog entry on rotation angles that may help as well.
Worst case, you'll need to add a new field to your data and manually enter the angles. If you need to do that, set up the symbology in advance so you'll instantly see the result of your work; allowing you to fine tune it in a relatively interactive fashion.
