Hello folks!

I am trying to use the dasymetric mapping tool provided by the USGS: WGSC

They provide a handy toolbox with the scripts enclosed.   I am trying to dasymetricaly map county wide population to census tract polygons.

I am using Arc10.0 student edition on a 64bit windows machine.

I am using the NLCD 2006  Land use map as my raster for ancillary data.  I am only testing it on one county in Michigan at the moment.  I have a county shapefile with the population field.   But every time I try to use the tool I get this message from arc.

Start Time: Tue Sep 18 09:16:55 2012
Running script DasymetricMapping...
Setting the INHAB Field
<type 'exceptions.RuntimeError'>: ERROR 999999: Error executing function.
Failed to execute (DasymetricMapping).
Failed at Tue Sep 18 09:17:19 2012 (Elapsed Time: 24.00 seconds)

Does anyone have any experience with this tool?  I have looked over the python code and I cant figure out why my data is incompatible with this tool.
