Hi there,
The output from the Generate OIS Intersection tool is geometrically fine, but the attributes leave a bit to be desired. It seems to have some odd summary of the input data in an OIS field, with a string that shows the input feature class and the OID of the input feature. Could you please include all attributes from the input features, or at least common ones like the names. I would suggest at a minimum that the input FC should be an attribute and the OID should be a separate attribute to allow joins back to the source data if required.

Thanks,
Marc
