Map comparison techniques , solutions, and/or tools

Discussion created by jskurupey on May 10, 2012
I am analyzing two maps of different scales.  I would like to quantify the difference between the two maps.  The data is in vector format but I am willing to rasterize it.  The data comprises of polygons, which contain categorical data that are string attributes.  The attribute represents a code of multiple environmental variables that have a range. 

Can anyone give me some directions in techniques, solutions, and/or ESRI tools to help with spatial analyses/statistics?  Source papers would also be welcome!
