Greetings...

I have an Aspect Raster based on a 30M DEM and a polygon landform feature class. Is there a way to calculate the percentage of north facing slopes (as well as all slope directions) that reside in my landform area polygons? 

Basically I want to determine which percentage of my landform or area polygon(s) is facing N, S, E, W, NE, SE, SW, NW.

I am using Arcgis 10.0.

Any and all information is greatly appreciated.

Thanks...

Mark
