In Landscapes 3 and 4, one of the students noticed that the Madison files have a "0" field.  I believe she was working off of the fixed data.  Is this no data?  An error? 

This must have to do with the fact that (in ArcGIS) I split one large grid into four grids, and there was an uneven number of rows to start with. One way to deal with the zero's would be to change the "no data" code to 0 (in the madison.fsc file and in the parameters dialog), as there are no other no-data values, I think.

Sorry about the inconvenience!
