I am trying to work out the best method for determining the include angle after running the viewshed tool.  Basically, I want to work out the angle of visibility from where there viewshed said my points were visible back to where the points are.  I have seen this done in other software packages (mainly dealing with wind farms).  Any thoughts or suggestions?
