Hi, I'm wanting to perform an operation that is similar to running zonal statistics, but I'm working with a raster that contains categorical values, so mean, range, and even variety are not useful to me. I want to count the number of raster cells of each value within a set of equal-area polygons (my domain grid)... I've seen an older thread that recommends converting said raster into polygons, intersecting with the polygon grid (my "zone" dataset), then running Calculate Areas... but frankly, I'm working with 30-m resolution data and my machine keeps crashing out because this results in hundreds of millions of polygons (even if I don't conform to the original raster cell boundaries). Does anyone out there know if there's an easier way to do this? Thanks! -Tiffany I'm sure you've already conquered your question by now, but for any future people users looking at this thread I would recommend using the Geospatial Modeling Envrionment (GME- Formerly "Hawth's Tools"). This environment contains the command "isectpolyrst" which will do exactly what you are asking. It also provides more functionality than the similar ARC tools as it has the ability to work with multipart feature. If you look at the similar tool in the help section (http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//00300000000t000000.htm) you can see some of the limitations of the extract values by polygon. Best, Ian

Important: Download "pywin32-216.win32-py2.6.exe" as that is Python version (v2.6) that ArcGIS v10.0 uses. DO NOT try and get fancy and upgrade to a different version - it will not work. Thanks for that little nugget of information. I had pulled down the newest version online rather than getting it from the install disc and it wasn't working well. Ian

We have a problem with some p-geodatabases in ArcGIS Geostatistical Analyst in version 10. Please convert your data to f-geodatabase (or shapefile). We are hoping to have a fix available post version 10 Service Pack 2. Sorry for the inconvenience Steve Lynch ESRI Hi Steve, I have been working out of a F-GeoDbase per your suggestion and GeoStatistical Analyst has been working perfectly. Thank you. Ian

Hi Hedera and Steve, When you've reached some type of consensus on this would you please post it? I came on here to start a thread on this exact problem. I am currently running SP1 as well. Not joining to any fields. I have experienced this same crash when doing ordinary or universal kriging. It always happens on either "Step 2 of 5" or "Step 3 of 5" when using the wizard. The I have emailed my error reports and have included my email with these reports. If it would help you Steve I can send you the address that the error reports are registered under. Any help much appreciated! GrizJohnson
