Hi everyone

I have a series of polygons (representing glacier margins) and I would like to know the azimuth of each segment of a polygon's edge. It seems that there were ways of doing this in the field calculator, but I've not been able to find out how to do it in Arc 10.1. Does anyone know how to get these azimuths?

Note that my license does not cover the Polygon to Line tool. So I'm wondering if I might need to re-draw the polygons as a series of seperate polylines - is this necessary and how would I then get the azimuth of each polyline?

Thanks in advance for your help!

You could use Et Geowizard to convert Polygon to Polyline and perhaps use this old script:

Find Polyline Angle
