calculating a directional distance from point to polygon

Discussion created by david9442 on Apr 6, 2012
I am using ArcGIS 10, and trying to do the following:

I have a layer file of points, and I would like to calculate the distance from each point to the nearest "eastern" polygon (U.S. state). I know there are tools for calculating distances from points to polygons (e.g., Near), but I don't know how (or, if you can) specify the direction of the polygon. 

Any suggestions?

Thanks in advance.
