Interpolation and Calculating Area

Discussion created by darais on May 11, 2010
I am relatively new to ArcView, and was wondering if there is a way to calculate area based off of the area covered by a certain color of IDW interpolation.  I have 4 colors/values and would like to know if there is a function that can deduce the area from this or if you have to use the manual area tool.  Also, on the same note, my interpolation forms a giant rectangle over the area and extends way past certain data points and then does not even cover other data points.  I have tried to fix the "extents" part of the interpolation but this does not change anything.  I would greatly appreciate any help!!! Thanks
