I'm encountering the same problem as described above, any ideas?
I've been using 10.1 sp1 for a while and the script tool which started throwing this error recently (it has worked without problems several times in the recent past)...DescribeData Method spatialReference does not exist
I don't use DescribeData anywhere, just spatial_ref=arcpy.Describe(ras).spatialReference
thanks for any help/suggestions.
