Calculating Area using an overlay of Vector and Raster Files in Arc9.3.1

Discussion created by jake34 on Mar 18, 2013
I am using 9.3.1 and am in a dilemma.  I have a two files, one raster and one vector.  The Raster file is symbolized into 5 classes of values 1-5 using the natural breaks (jenks) classification.  The Vector file also contains 4 classes 1,2,4, & 5.  I would like to overlay the two files and determine how much area (acreage) vector classes 4 & 5 represent within the Raster Classes of 1 & 2.  Ie.....For Raster Class #1, I need the acreage that Vector Class 4 represents and acreage that Vector Class 5 represents, both individually.  I need the same for Raster Class #2.  If someone could please help me solve this dilemma I would greatly appreciate it.
