Philip correctly described the only way to move this data to grass
using ungenerate, but you will have to repeat the procedure for every
theme in the Arc database, making it very tiresome in for your data
supplier if there are many different themes.
Such confusion about such a relatively simple conversion!
The truth is that the data supplier need only ungenerate once, assuming
that he/she dumps all Arc attributes at that time.
The rub is that GRASS only allows one attribute at a time to be
associated with the polygons. Therefore, *on the user's side*, at the
time the file is imported with v.in.arc, the user will have to pick an
attribute, or, alternatively, create one GRASS layer per attribute.
I would not recommend the DXF conversion route. Many have reported
that attributes are lost with this technique.
