zonal analysis

Discussion created by cti2580 on Sep 23, 2011

I am working with ArcGIS 9.2. My goal is to define and simplify representative crop ratation per each county from time-series data. Now I'm trying to extract 1st, 2nd, 3th frequent values among about 250 crop rotation data by each zone (county level, 315 counties in several states) from 2008 to 2010. These are huge data including LA, TN, AL, ..., VA, etc. so I wan to use automated method such as model builder or coding (but I have no experiences for this approach). Please let me know how to define/extract above information.

Thank you in advance and I look forward to your response.
